HOURS/DAYSafter casting

2∆T (°C) 4

6h 12h 24h 3gg

8 19

In these structures, in fact, due to the generation of heat from hydra-tion of cement and the low thermal diffusivity of the concrete, a hightemperature gradient can be measured between the concrete surface,which cools rapidly to ambient temperature, and the internal core whichrises and drops slowly due to the natural thermal insulation property ofconcrete. If the temperature differences are excessive, thermal crac-kings occur (right from the first few hours after casting) of substantialwidth (>0.5 mm), dangerous both for the statics and durability of thestructure.

Maxibeton® is a special concrete produced using a low-heat (LH) poz-zolanic cement and high dosage of superplasticizer to reduce the cementdosage, in order to minimise the thermal gradients in mass concretestructures. The use of Maxibeton®, therefore, allows to reduce the riskof cracking, due to excessive heat developed in massive structures witha low surface area/volume ratio.

Maxibeton® is a very low heat concrete for use in above-ground mas-sive structures exposed to the action of rain (XC4) and sea water (XS1),and for hydraulic and underground structures in contact with modera-tely aggressive soils and water (XA2).

Table 1: compressive strength (N/mm2) development of Prebetonunder standard laboratory conditions (20°C) and using a low-pressure steam curing (duration 18 hours: 3 hours pre-curing,heating at 10°C/h, curing temperature 45°C).

Table 1 shows the development of the compressive strength of Prebetonconcrete.

Prebeton special concrete with aggregates of Dmax 16-22 mm is availa-ble in three consistence classes (S4-S5-SCC). The concrete code must alsoinclude the workability.

For these structures, manufactured using industrial building criteriabased on continuous daily cycles, the ability of the concrete to reachits mechanical properties a few hours after casting is of primaryimportance in order to be able to demould and subsequently re-use the formworks for the next production cycle.

Prebeton is a special concrete, the composition of which is designed toreach high mechanical performance in a short period of time in order tocomply with typical precast needs. The use of rapid-hardening cementand high dosage of superplasticizer allows high performance to beobtained, while at the same time guaranteeing the durability of theconcrete in all environmental exposure classes (except those requiringthe use of an air entraining admixtures) including the most severe(XA3) according to EN 206-1.

Table 1: Density, thermal conductivity and slab thickness required toobtain the same thermal resistivity.

Table 1 shows the thermal conductivity of Isolbeton compared to that ofa traditional cement mortar.

Used in residential buildings, offices, locations with public access,hospitals, etc., to improve living comfort by reducing heat loss throughthe roof/floor slab and absorbing noise transmitted from occupiedrooms, and at the same time providing savings in building managementcosts. Isolbeton is a special cement mortar prepared using lightweightaggregate of foamed polystyrene that give the mortar a density 4 to 8times lower than a traditional cement based material used for screeds.The particular lightness of Isolbeton base layers increases thermal resi-stivity with respect to a fill material of equal thickness in traditionalcement mortar, and as such reduces the amount of heat loss throughthe slab. The reduced heat loss also leads to lower interior heating costsand improved comfort, in that Isolbeton reduces heat loss from therooms once the heating system has been switched off. It follows thatthe time required to restore the target temperature (18°C) in the roomsafter the heating has been switched on again is shorter if the floorslabs are made up of Isolbeton instead of ordinary cement mortar.

Isolbeton is available in two versions depending on the level of ther-mal resistivity required:- Isolbeton 300 – lightweight thermo-insulating cement mortar of nominal density 300 Kg/m3;- Isolbeton 600 – lightweight thermo-insulating cement mortar of nominal density 600 Kg/m3.

Thanks to their special ingredients and particular mix-design,Isolbeton cement mortars casted in thicknesses of 35-55 mm guaranteethe same thermal resistance as an unrealistic and approximately 650mm thick concrete layer!Isolbeton is also pumpable and has a high-workability. Consequently, itis simple and quick to cast, providing inevitable advantages in terms ofconstruction costs and times. If, on the one hand, the extreme lightnessof the Isolbeton cement mortar increases thermal resistance, on theother, it has a compressive strength typical of a fill material (around 1MPa at 28 days). It is recommended, therefore, that a few days aftercasting Isolbeton (according to the temperature on job-site) a screedis poured over the top, of suitable thickness and rigidity (at least 4.0cm and reinforced with a steel mesh) and with sufficient mechanicalstrength to resist the compressive and shear stresses induced by liveloads acting on the floor.

es Neoisolbeton™ is an innovative special thermo-insulating, sound-absorbing and high performance lightweight cement mortar madewith Neopor®, a lightweight expanded polystyrene (EPS)aggregate containing particles of graphite, for use as base layersand filling material prior to laying screeds for ceramic, stone orwooden floor finishes.

Neoisolbeton™ improves living comfort in residential buildings,offices, hospitals, etc., and leads to significant savings in buildingmanagement costs by reducing both the heat loss through roof/floorsand the impact of noise from occupied rooms. Neoisolbeton is a specialcement mortar manifactured with Neopor®, a lightweight expandedpolystyrene aggregate containing graphite, which gives the concrete adensity 4 to 8 times lower than that of traditional cement mortars usedfor screeds. The low density of Neoisolbeton base layers leads to anincrease in thermal resistivity compared with that of a layer of the samethickness made with Isolbeton and thus reduces the amount of heatloss through the slab. The lower heat loss permits a reduction inrunning costs and improves overall comfort as Neoisolbeton limits thetemperature decrease in the rooms once the heating system has beenswitched off. As a result, the time required to restore the targettemperature (18°C) in rooms, when the heating has been switched onagain, is shorter if the slabs are made using Neoisolbeton instead ofordinary cement mortar.The conductivity of Neoisolbeton™ is at least 15% lower than that ofIsolbeton, which makes it ideal for buildings with high energyefficiency.Furthermore Neoisolbeton™ is high-workable and pumpable mortar.Neoisolbeton is simple and easy to cast reducing drastically layingtimes, a clear advantage to the construction business. The very lowspecific density of Neoisolbeton cement mortar increases thermalresistance and, at the same time, it has a compressive strength typicalof a filling material (over 1 MPa at 28 days). It is recommended that afew days after laying Neoisolbeton (the waiting time is a function ofthe temperature on the job-site), a screed is laid over the top, ofsuitable thickness, rigidity (at least 4.0 cm thick and reinforced with asteel mesh) and mechanical strength to resist the compressive andtangential loads induced by live forces acting on the floor. Termobeton1400, a lightweight concrete with structural expanded clay, can be usedas lightweight screed further improving the thermal resistance of theentire floor.

es Lightweight concrete with structural expanded clay of adjustabledensity:

- for subgrade or for roof loft before the application of the membrane barrier (TERMOBETON 800);

- for construction of structural elements (pillars, beams and slabs) of r.c.structures (TERMOBETON 1800)

The special concretes of the Termobeton series combine the mechanicalproperties of traditional concretes with the thermo-insulating proper-ties of cement mortars prepared using lightweight aggregate of foamedpolystyrene (Isolbeton).Thanks to the option of being able to modify the percentage of light-weight aggregate in the mix, Termobeton can be produced with increa-sed mechanical characteristics (Termobeton 1800), while at the sametime guaranteeing a substantially lower density (1600 ÷ 2000 Kg/m3)than that of a traditional concrete (2250 ÷ 2400 Kg/m3).Thanks to the reduced weight, load bearing structures created inTermobeton 1800 can, therefore, be used for the following purposes:- construction of tall buildings on soil of poor load-bearing capacity;- in seismic zones to reduce the inertia forces induced by seismicmotions;

- for the construction of vertical extensions to existing buildings whenrequiring to reduce the weight of the additional portion acting on theoriginal structure;

- repair works to existing wooden floors to provide a stiffening course ontop of the existing floor structure;

- consolidation works on brick or stone arches when needing to cap thestructure in concrete.

Termobeton 1800, when used for the suggested applications, themechanical performance of the concrete is more or less identical to thatof a traditional concrete of equivalent fck-cube, with the advantage ofdrastically reducing the masses in play by around 30%.

Termobeton 1400 improves the lightness aspect without affecting theelasto-mechanical properties, which remain comparable to those of a tra-ditional concrete used for other works.Thanks to its properties, Termobeton 1400 can be used to advantageeither alone or in combination with base layers in Isolbeton to providecompletion toppings of horizontal concrete surfaces. The combined useof Isolbeton and Termobeton 1400 produces thermal resistances com-parable with those obtainable using panels of synthetic material but fargreater than those obtainable using an ordinary cement mortar.

In order to obtain the same thermal resistance as a package consistingof 10 cm of Isolbeton 300 and 5 cm of Termobeton 1400, in fact, itwould be necessary to lay a traditional cement mortar screed of thickness 2 m.

Termobeton 800, enhances the lightweight characteristics of the con-cretes in the range and, as such, improves their thermal insulation pro-perties. For this reason, Termobeton 800 is used to great advantage inthe realisation of base layers on roofing slabs, the greatest source ofheat loss, prior to installing the impermeable layer. In addition,Termobeton 800 allow base layers suitable for foot traffic to be laid onfloor slabs prior to the screed for the actual floor finish. Thanks to itsexcellent thermal insulation properties Termobeton 800 can also beused to fill the gap between the two skins of cavity walls in order toimprove thermal insulation.

Table 1 reports the finishing times for Betonpav compared to a concreteof the same fck-cube but not designed specifically for paving.

Thanks to its special mix-design, its higher content of fines than in aconcrete of equivalent compressive strength class and the use of specialadmixtures, Betonpav satisfies the requirements of the pavements bothwhile in service and during the construction phase. As far as about thelaying, Betonpav, due to its particular mix in terms of cement and finescontent, is easier to cast and vibrate, thus facilitating the cast in siteand making life easier for workers. In addition to its particularcomposition, the type of cement used and the nature of the chemicaladmixtures contained, Betonpav also drastically reduces the initial andfinal setting times with respect to a similar mix of equivalent fck-cube.Thanks to this attribute, Betonpav allows to apply dry-shake toppingsvery quickly, including in the presence of relatively low temperatures,avoiding the necessity to carry out the work during the night followingthe cast, with the resulting high costs due to the inevitable "day ofrest" conceded to the worker who carried out the overnight finishingoperations. Betonpav, in fact, is characterised by much faster settingtimes than normal concretes, i.e. less than 8 hours at 20°C. Thissignifies that if the site is organised to carry out the cast early in themorning and complete it by lunch time, the finishing operations can beconcluded prior to 8 pm in the evening, ensuring that the personnelinvolved can continue work without interruption on the following day.

es Betonpav ZJ® is a very high-performance, and shrinkagecompensating concrete, particularly suited for the construction ofjointless concrete slabs, specifically for:

- flooring for goods storage and handling warehouses using lift trucks and mobile pallet rackings

- slabs on precast beams

- pavements of thickness between 8 and 12 cm

Betonpav is a very high-performance concrete mixed using the mostinnovative ingredients resulting from research work carried out overrecent years in the concrete technology, i.e. superplasticizer andshrinkage reducing admixtures and expansive agents. Thanks to itsparticular composition, Betonpav ZJ® induces expansion into the slab,including in the absence of prolonged wet curing. The benefit derivingfrom the expansion is also enhanced by the dimensional stability ofBetonpav ZJ® stemming from its modest shrinkage values. The use ofsuperplasticizer, in fact, together with expansive agents and shrinkagereducing admixtures, leads to a much greater combined effect than thatobtainable with the same ingredients used individually. The reductionin shrinkage following the use of Betonpav ZJ® is somewhat drasticcompared to a concrete of equal water/cement and aggregate/cementratio, as can be seen in Figure 1.

Thanks to its improved dimensional stability, Betonpav ZJ® is particu-larly suitable for laying very thin concrete slabs between 8 and 12 cmthick, allowing the curling to be reduced to acceptable values, enginee-ring wise. In other words, with Betonpav ZJ®, it is no longer necessary to cast a

- floors of industrial buildings and workshops

- floors for goods storage and handling areas, external and internal

- flooring for garages, multi-storey car parks (including with heavy traffic)

Betonpav Expan is a high-performance concrete prepared using super-plasticizer and accelerating admixtures and expansive agents. Thanks toits particular composition Betonpav Expan introduces beneficial "pre-compression" into the slab as a result of the restrained expansion,which allows total elimination of contraction joints in floors of area600-900 m2. It remains understood that the total elimination of con-traction joints and the production of a crack-free surface also dependon the presence of the appropriate restraining reinforcement in thefloor (at least two steel meshes of diameter 8 mm with mesh size 20x20cm, positioned at a distance of 1/4 of the floor thickness from the topand bottom surfaces respectively of the slab). As an alternative to theuse of steel mesh, metallic or structural polymer fibre can be used torestrain the expansion. For this purpose, Betonpav Expan is availablein versions Betonpav Expan SF and PF reinforced with steel fibre (SF)or structural polymer fibre (PF) respectively. Another condition forobtaining a jointless slab, regardless of whether Betonpav Expan (forpavements with double steel mesh reinforcement) or Betonpav ExpanSF/PF (for pavements reinforced with structural fibers) is used, is anefficient wet curing of the surface immediately after the finishing ope-rations have been completed. Thanks to the restrained expansion effectin the presence of a correct steel layout (or following the use of thefibre reinforced versions Betonpav Expan SF/PF) and the appropriateprolonged wet curing, Betonpav Expan can be used in the constructionof jointless slab and in which the only interruptions are represented byconstruction joints between daily casts. This signifies reducing floormaintenance and enables the use of mobile pallet rackings the correctoperation of which requires continuity, i.e. the absence of interruptionsin the floor surface. In addition to shrinkage compensation and, as aresult, the possibility of constructing pavements without contractionjoints, Betonpav Expan also has the characteristics of a concrete desi-gned and mixed specifically for the flooring sector, i.e.:- fines content higher than a concrete of the same strength class,making Betonpav Expan easier to cast and vibrate;- much shorter initial and final setting times than those of a similarconcrete mix of identical fck-cube; with the result that Betonpav Expancan be used for applying dry-shake toppings in much shorter times,including at relatively low temperatures;

Fibrobeton is available in the POLI version that incorpo-rates non-structural polymer fibres, POLI STR with structural poly-mer fibres, METAL with metallic fibres and HYBRID which containsboth non-structural polymer fibres and metallic fibres for:- slabs of medium-low thickness (12-15 cm)

- slabs without steel mesh

- thin pavements overlying existing floors

- floors of industrial buildings and workshops subjected to impact forces from falling metal objects (anti-shock floor coverings)

FIBROBETON

In industrial concrete slabs constructed using traditional techniques, thesteel mesh does not have any structural purpose, but is used instead tocontrol thermo-hygrometric movement . Quite often, this mesh is positio-ned incorrectly without, for example, using spacers that place it at appro-ximately 1/3 of the slab thickness from the top surface. A mesh mistakenlyplaced at the bottom of the slab cannot perform the function it was desi-gned to carry out. Furthermore, even when the mesh is positioned cor-rectly, any overlapping of the edges of the mesh can result in insufficientconcrete cover to the steel, and as a result lead to unsightly cracking.These problems can be greatly reduced thanks to the use of FibrobetonMetal or Fibrobeton Poli STR.The metallic fibre reinforcement of Fibrobeton Metal or the structural polymerreinforcement of Fibrobeton Poli STR, in fact, allows:- elimination of the labour intensive operation of correctly placing thesteel mesh;

- cost savings in the amount of steel mesh and spacers necessary for itscorrect positioning;

- improvements in the safety of workers who are not forced to walk on thereinforcement during the concrete casting.

In addition to these economic benefits, Fibrobeton Metal and FibrobetonPoli STR also provide significant technical advantages, in that due to thecontribution of the fibre beyond the elastic limit, it is possible to reducethe thickness of the flooring as well as substantially limit the appearanceof macroscopic cracks on the surface of the floor. Fibrobeton Metal andFibrobeton Poli STR, in fact, are capable of counteracting the stressesthat form in the concrete to reduce crack width to below 0.1 mm.Fibrobeton Metal and Fibrobeton Poli STR are also particularly useful forpavements subjected to falling metal objects, such as often happens inengineering workshops. The fibre reinforcement, in fact, can transformFibrobeton Metal and Fibrobeton Poli STR into a tough and ductile con-crete capable of resisting collisions and impacts. The range of Fibrobetonproducts includes special Fibrobeton Poli concretes reinforced with non-structural polymer fibres. Fibrobeton Poli is particularly suitable for slabslaid during hot and windy periods, when there is a high risk of cracking

- roads and paths in environmentally protected zones

- sport tracks and golf paths

- parking lots

The use of pervious materials in the road construction sector isbecoming more and more widespread, both to obtain safer drivingconditions during adverse weather and as a tool for regulatingrainwater runoff.The most common use is open graded asphalt or, alternatively,interlocking paving blocks.The advantages linked to the ease of laying of bituminous concrete areoffset by the high priced paid for the raw materials, asphalt inparticular, the cost of which increases in line with oil prices. In the caseof double layer self-draining/sound-absorbing pavements, the costsincrease even further in terms of the construction works involved andthe regular maintenance to be carried during the service life of theinfrastructure.The use of interlocking paving blocks can also be onerous due to thetimes and costs involved. The surface regularity characteristics requiredfor the work are not always guaranteed. In the case where the structureis destined to support the passage of dynamic loads, there is anadditional problem linked to the poor stability of the road surfacewhich, over time, can suffer from local subsidence with frequentdisplacement of the blocks. Drainbeton® is the solution that cansatisfy a wide range of construction needs, both structural andaesthetic, and at the same time reduce construction and maintenancecosts.

esWORKABILITYThe mix is designed to be placed using slipform paving machines. Theworkability of the mix means it can be casted using the same methodsand machines as normally used for road paving works.In addition to allowing fast laying times, its workability also guaranteesfull control over final flatness and thickness characteristics as well asthe surface regularity of the pavement.

What’s more:- the concrete is casted "cold", and as such there are no bitumen fumesemissions during paving operations and no risk to operators.

- the concrete can be laid at ambient temperatures much lower than therecommended minimums for bituminous mixtures.

- the low hydraulic shrinkage of the material means no contractionjoints.

- the coloring concrete is for all thickness (not just surface) resultingin long-lasting uniformity.

- the subgrade requires the same regularity and load-bearingcharacteristics as those normally required in road construction.

STRENGTHAs early as 2-3 days after laying, Drainbeton® reaches compressivestrength levels sufficient to open the road to vehicular traffic, includingsite equipment. The 7 and 28-day strengths of Drainbeton also allowsit to be used for road surfaces with high volumes of traffic.

MEASURE OF SURFACE DRAINAGEThe high percentage of interconnected voids allows Drainbeton® todrain more than 30 l/sq.m per second, while still guaranteeing highload resistance values.

DE-ICING EFFECTThe open matrix of Drainbeton® allows the continuous circulation ofair, accelerating the thawing process of ice or snow.

LESS HEAT ABSORPTIONThe light color of the material and the high porosity of the mix allowsa lower heat absorption than in bituminous concrete, and a faster heatdissipation.

GROUNDWATER MITIGATIONThe high self-draining characteristics make Drainbeton® particularlysuitable for applications in environmentally protected zones where it isimportant to return rainwater to the soil.

es FILTRATIONThe filtering structure of the material reduces the need for rainwatertreatment and limits the harmful effects of potential pollutants.

RESISTANCE TO FIRE AND HYDROCARBONSDrainbeton® is resistant to fire and hydrocarbons. This allows it to beused in areas exposed to the risk of fire or fuel spills (e.g. car parks,petrol stations, fuel storage areas, etc.).

MAINTENANCEThe physical, mechanical and aesthetic characteristics of Drainbeton®remain unaltered over time and the pavement does not require anyparticular maintenance.For applications in zones affected by high levels of dirt or dust, it mayoccasionally be necessary to wash the pavement with high-pressurewater cleaning to maintain drainability.

FOR USE IN A DOUBLE LAYER POROUS PAVEMENTSDrainbeton® can be used in combination with an open graded asphaltwearing course to provide a dual permeable/sound absorbing roadpavement. Drainbeton® can therefore replace the base course andbinder (which are normally impermeable), giving the package not onlypermeability and sound-absorption, but also lower deformability andgreater load resistance, thus prolonging the service life of thepavement.The advantages in using this solution can be summarized as follows:- Thanks to the asphalt wearing course, the permeable road pavementappears “normal” and as such is well-received by both PublicAuthorities and road users.

- For the same reason, the surface grip, smoothness and compatibilitywith road markings are maintained.

- The presence of two highly porous layers gives the paving a high self-draining capacity as well as sound absorbing properties at differentsound frequency levels.

- Thanks to the load-bearing capacity and fatigue strength of theconcrete, the pavement has a long service life with minimummaintenance, affecting principally the asphalt wearing course.

- The double permeable layer with its selfcleaning action reducesblockages in the interconnecting voids to a minimum, thusprolonging the self-draining properties of the material over time.

- The construction and maintenance costs are lower than those of atraditional road package.

es DESCRIPTION Idrobeton® is a special concrete manufactured using hydrophobicadmixtures or with a microsilica with pozzolanic activity suitablefor all underground structures in the presence of groundwaterand for hydraulic and water retaining structures, such as:

- walls of cellars or underground car parks

- walls of underground rooms or underground car parks below the water level

- foundations and walls of swimming pools and potable water tanks

- foundations and walls of tanks containing effluent or water contaminated with aggressive chemicals

The Idrobeton® concretes are designed to satisfy all waterproofing andhydraulic sealing requirements of any structures. The range includesIdrobeton W, a special concrete mixed using hydrophobic admixturesthat give the mix a reduced capacity to absorb water, which makes itparticularly suitable for underground walls in contact with water resul-ting from an inefficient rainwater collection and disposal system.The reduced water absorption characteristic of Idrobeton W compared to aconcrete of same water/cement ratio, also allows it to be used in the con-struction of walls below the water level, even if only a few metres.The degree of impermeability of concrete structures can be increasedeven further thanks to the use of the special Microsilbeton concrete,prepared using a microsilica with pozzolanic activity.Thanks to the low water/binder ratio, and the use of superplasticizerand pozzolanic material, the porous structure of Microsilbeton is affec-ted by a "refinement" process that reduces the dimensions of the capil-lary pores, resulting in a high degree of impermeability. This impermea-bility is sufficient for use in the construction of swimming pools andtanks without needing to carry out any further waterproofing treat-ment, thus substantially reducing the cost of the structures.In the presence of sewage or water containing aggressive chemical sub-stances, the structure can be built using Waterproofbeton®. This con-crete is actually "impermeable" with a permeability coefficient approxi-mately ten orders of magnitude (10 billion times) lower than that ofincoherent soil.Thanks to this impermeability, which is guaranteed by a special formulaworked out by the Betonrossi Laboratories, Waterproofbeton® can gua-rantee a perfect hydraulic seal in all tanks, thus preventing the contai-ned polluting liquids from contaminating groundwater and surroundingsoils.Waterproofbeton® also guarantees that the structures are inherentlyresistant to aggression by any of the chemicals specified for exposureclass XA as provided for in standard.

es DESCRIPTION Espanbeton® is a shrinkage compensating concrete suitable for:

- foundations without or with reduced number of joints- foundations of masonry buildings- load-bearing and shear walls, and for increasing the section ofconcrete pillars during restoration works and seismic strengthening of existing buildings

- repairing existing structures showing signs of serious degradation andrequiring the reconstruction of reinforced concrete elements with orwithout modifications to the original section

- embedding part of the precast column into the cavity of the foundationelement

Espanbeton is a shrinkage compensating concrete prepared usingsuperplasticizer and expansive agents (Figure 1). These additions allowa compressive strength to be exerted in the section of the concrete ele-ment, capable of resisting the tensile stress due to the hydraulic shrin-kage of the concrete that would otherwise lead to the formation ofcracks in the structure.

Espanbeton® is particularly useful when the purpose of the concrete is toanchor two different concrete elements, such as for embedding part of theprecast column into the cavity of the foundation element. In this case,Espanbeton® results in the perfect anchoring of both structures, in that,thanks to the expansion phenomenon, there is no separation of the con-crete from foundation or from the precasted pillar caused by hydraulicshrinkage typical of ordinary concretes. A problem similar to that mentio-ned above also arises in restoration works requiring, for example, anincrease in the section of existing pillars resulting from a change of useof the building or from works required to modify the rigidity of a verticalelement to satisfy seismic requirements. The same need to increase thesections of structural elements occurs in viaducts constructed a few deca-des ago, which require updating to comply with the loads indicated bynew standards. In the same manner, there is also a risk of cracking when repairing adegraded concrete structure requiring the removal (and subsequent repla-

escement) of significant portions of concrete. This is the case of concreteelements affected by corrosion of the steel induced by chlorides (deicingsalts, seawater) and/or by carbonation, as a result of freeze-thaw cyclesor the aggressive action of sulphates or free carbon dioxide present inwater. In these situations, due to the effect of the shrinkage preventionby the adhesion to the existing structure (which has completed its shrin-king over the years) the structural enlargement (or the portion of the sec-tion repaired) is subjected to tensile stress that, unless suitably control-led, can lead to separation and cracking of the concrete used for thereconstruction or enlargement of the original section. Thanks to the pre-compression state generated by the expansion restraining action of thereinforcing steel and the adoption of a correct wet curing procedure,Espanbeton® concrete allows the tensile stresses induced by the preven-ted shrinkage to be counteracted. The precise composition of the mix, andthe use of expansive agents in strictly controlled measures, allowsEspanbeton® to exert a precompression force greater than the tensilestress induced by the shrinkage and, consequently, prevent separation ofthe concrete from the sub-base and the appearance of cracking that wouldadversely affect both the statics and durability of the structure. In thecase of repair works to brick buildings requiring underpinning to preventthe structure from collapsing, one of the main problems relates to the factthat, due to the shrinkage effect, the new foundation will not be able toaccept any loads from the building until there is further settlement of thewalls, resulting in more damage to the upper works which would then besubject to further cracking. To avoid this ulterior settlement, a somewhatdifficult and costly technique is often used. This involves injecting expan-sive grouts or resin between the new foundation and main structure afterthe concrete has hardened or using post-tensioning techniques on theconcrete structure. These problems can be resolved quite easily usingEspanbeton®, in that the expansion produced during the concrete harde-ning allows the subsequent shrinkage to be controlled, thus preventingany separation of the underpinning from the main structure and, therefore,allowing it to be become statically stable without any further settlement.Espanbeton®, finally, is particularly suitable for constructing medium-large surface area raft foundations that need to be jointless or have a limi-ted number of joints. For these structures, in fact, shrinkage is particularlypronounced, in that they are characterised by a high ratio between thesurface exposed to evaporation and the volume of concrete. Therefore, ifthere are no joints, the prevention of concrete shrinkage leads to a seriousrisk of cracking ("natural joints") which is not only statically dangerous butalso could cause infiltration of water from the underlying soil. Thanks tothe expansion retraining effect of the reinforcement in the foundation, anda correct wet curing procedure (guaranteed by protecting the surface usingpolypropylene sheet or wet geotextiles), Espanbeton® can control the ten-sile stresses induced by the shrinkage and thus allow a raft to be construc-ted jointless, or at least with a limited number.

es DESCRIPTION

The material used to fill excavation of trenches in roads for laying pipes,ducts and cables must have a high load-bearing capacity sufficient to pre-vent the bituminous road surface from being cracked and damaged by for-ces deriving from the passage of vehicles. The formation of the so-called"ruts" in the road surface, in fact, would constitute a serious hazard fortransiting vehicles. Fillbeton® has a far greater load-bearing capacitythan a non-cohesive soil compacted. Fillbeton® can, therefore, also beused for backfilling excavations in highways or similar subject to the pas-sage of heavy vehicles. Unlike traditional solutions in which the excava-tions are backfilled using granular materials and then compacted,Fillbeton® has the undeniable advantage of speeding up backfilling ofthe excavation thanks to its high fluidity. Consequently, once casted, thehigh fluidity of Fillbeton® ensures that it totally fills the entire sectionprofile of the excavation and does not require any vibration. This consti-tutes an enormous advantage in terms of the reduction in manpower andincrease in the linear metres of trench that can be filled in one workingday, with the inevitable positive influence on the costs of the works.Fillbeton® is also easily removable, in that it can be excavated withoutproblem for extraordinary maintenance purposes or for pipe/duct inspec-tions. Fillbeton® is available in a wide range of colours. This means thateach service provider (electricity, gas, water, communications, etc.) canfill his trenches with his own particular colour, allowing immediate iden-tification of lines, pipes, etc., when the need arises to carry out inspec-tions or maintenance activities, especially in built-up areas in the presen-ce of numerous different underground services. Fillbeton® is a special concrete prepared using aggregates on a conti-nuous grading curve, superplasticizer and surfactants capable of givingthe mix excellent fluidity to allow simple and rapid pouring. The fluidityof the mix also signifies that no compaction is needed, in that oncepoured, Fillbeton® adapts itself perfectly to the walls of the excavationand, thanks to its load-bearing and dimensional stability characteri-stics, does not suffer any damage from loads during service.

FILLBETONR

Lightweight concrete specifically for filling excavations forlaying pipes and ducts.Fillbeton® is particularly useful for filling:

- excavation of trenches for gas pipe lines, sewerage systems, electric andoptical fiber cables

- temporary excavations

- cavities with difficult access

In addition, Fillbeton® can also be used to improve the geo-mechanical properties of soils instead of using mixed, rolled andcompacted materials. Fillbeton®, finally, represents a valid alter-native for cement-bound granular material in the stabilizationof low-bearing capacity soils.

esFillbeton®, therefore, can eliminate all problems typical of backfillingusing natural soils that, due to their slow and relentless settlement overtime following the passage of vehicles, tend to subside and formdepressions that prejudice the safety of the road surface. Finally, thecellular structure that characterises Fillbeton® renders the materialeasy to excavate if and when it needs to be removed for access to pipesor ducts for ordinary/extraordinary maintenance or for inspection pur-poses.- Fillbeton®: concrete with a cellular structure, high fluidity, excellentload-bearing capacity and dimensional stability for backfilling trenchesdug for gas, sewerage systems and for electricity and fibre-optic cableducts. Fillbeton® is easy to excavate for inspection and/or maintenancepurposes. To this end, Fillbeton® is available in a number of differentcolours for easy and immediate identification of the underground service.

- Fillbeton® is also available (Table 1) in six different versions denotedby their densities between 1000 and 2000 kg/m3 and compressivestrengths between 0.6 and 2.0 N/mm2. In this way, the version ofFillbeton® touse can be selected according to the required load-bea-ring capacity: the lower density Fillbeton® concretes can be used forbackfilling in zones subject to the passage of light loads or where, as aresult of frequent maintenance, the concrete needs to be excavatedquite often. On the other hand, when backfilling trenches in roads sub-ject to the passage of heavy vehicles and a greater load-bearing capa-city is required, a higher density Fillbeton® possessing a much highercompressive strength can be used.

esDESCRIPTION Architecturalbeton® is a special concrete for fair-faced structuralelements for indoor and outdoor settings in direct contact withrainwater, used specifically for:

- infrastructures (bridges, viaducts, airports, railway stations, etc.) with partiallyof fully exposed elements

- fair-faced concrete walls of internal private house or public buildings

- concrete external front of public and/or private buildings

- internal and external stairways with exposed load-bearing structure

- exposed floor of public and private buildings

- cantilevered with exposed underside face

- elements of urban design such as retaining walls, bench sites, fences, railings

- architectural elements or works of art (sculptures)

Architecturalbeton® is a special concrete subjected to strict quality controlof mix ingredients and composition during production, in order to guaranteethe excellent fair-faced concrete structure. In particular, in the production of Architecturalbeton®:- only potable water complying with EN 1008 is used. Recycled washwater is notused as the suspended solids could alter the appearance of the fair-faced of thestructures;- the aggregates are subjected to strict checks as regards source, in order to avoidsupply variations that could affect the colouring of the concrete;- only frost-resistant aggregates with a water absorption less than 1% are used inorder to prevent surface exfoliation as a result of a freeze/thaw cycle, above all incold climates;- the dosage of cement and extra fine particles is higher than in a similar concretenot destined for use in fair-faced elements, and moreover never less than 350kg/m3. This allows the concrete to faithfully reproduce the complicated geometricshape and texture of the formwork (above all if in wood);- strict checks are carried out on the water/cement ratio of the mix, in order toensure that there are no variations of more or less than 0.02, as this could affectthe final colouring of the concrete.It remains understood that the final result of the fair-faced finish not only dependson the quality of Architecturalbeton®, but also, and above all, on the actualconstruction works. In particular, the quality of the fair-faced also depends onthe type of formwork used and the type and dosage of releasing agent. As faras the releasing agent is concerned, this should be applied as a thin uniformfilm covering the entire surface of the formwork. Incorrect or excessive use ofthe releasing agent can lead to "ripping-off" of the surface cement or theappearance of unsightly dark stains. Similarly, during the concrete cast, suita-ble precautions must be adopted to prevent cement from leaking through thejoints in the formwork and segregation of the coarse aggregate, and to ensurethat the concrete is vibrated correctly to prevent the formation of macroscopicvoids.

ARCHITECTURALBETONR

Spec

ial Co

es Finally, surface curing is of vital importance for obtaining the appropriate fair-faced finish. In this respect, wetting the surface with water or covering withimpermeable sheeting, which tends to result in the formation of dark areas(wet) alternating with lighter colour areas (dry), should be avoided. Instead,the concrete should be cured using sheets of geotextile material. Finally, interms of design, it is advisable to divide large surface areas into smaller zones(mirroring) using geometric patterns or fair-faced spacers that limit the per-ception of the inevitable variations in tone that would otherwise stand out insuch a large surface area .Architecturalbeton® is available:- in version Architecturalbeton® 35 for interiors and exteriors protectedagainst rain elements (XC1, XC3);

- in version Architecturalbeton® 40 for external structures exposed to rain(XC4), marine environments (XS1) or in contact with solutions containingchlorides (XD2) or in moderately aggressive chemical environments (XA2).

Nuclearbeton® contains special heavyweight aggregates (such asbarite) to improve its shielding properties against nuclear radiation.Barite is a mineral composed of barium sulfate (BaSO4) with a highspecific mass (4000 and 4500 kg/m3); barite aggregate is usedreplacing ordinary crushed aggregates (siliceous or calcareous) tomanufacture a heavyweight concrete with a density 2700 kg/m3 higherthan that of an ordinary concrete and consequently with much greatershielding properties to X and gamma ray radiation.

Nuclearbeton® is specifically recommended for:- radiation shielding in medical or nuclear applications- nuclear radiation treatment room- radiation shielding for medical cyclotron- work areas of the nuclear medicine department- nuclear plants- ballasting for pipelines and similar structures

The procedures for mixing, transporting, and placing Nuclearbeton®are similar to those used in conventional concrete construction;however, special expertise and thorough planning are necessary for thesuccessful completion of this type of concrete work. The use ofNuclearbeton® is a specialized field, and it is advisable that the workbe undertaken by qualified personnel. Nuclearbeton® allows to reducethe thickness of radiation shielding elements compared to that requiredfor ordinary concrete. In Nuclearbeton®, vibrators have a smallereffective area, or radius of action; therefore, greater care must beexercised to insure that the concrete is properly consolidated in orderto obtain high density for the reinforced concrete elements.
