CLC is called as lightweight cellular concrete and is also called as foam concrete. Cell Light Weight Concrete (CLC) is a lightweight concrete version that is produced as normal concrete under ambient conditions. The CLC blocks are a cementitious material made by mixing the cement slurry. A stable, preformed, locally made foam is injected into this slurry to form foam concrete. The fresh foam concrete looks like a milk shake and the volume of slurry in the foam dictates the cast density of the foam concrete.
Advantages in detail:
• Savings of raw material: The enormous savings described when using CLC are multiple, continuing with substantial savings in raw material (without gravel required), in dead load of great height reducing almost by half. Taking into account that a substantial amount of steel is needed only to support the weight of the structure, the steel requirement could be reduced by hundreds of tons in the high increase.
• Considerably lower weight: The weight reduction is obvious in transport, where it can produce almost twice the volume of building material, has an impact on the stretch, where larger panels can be taken, or the total capacity in span . Alternatively, less relocation of the crane is required.
• Thermal Insulation: Thermal insulation is increasingly becoming the most important issue in the planning and construction of buildings. There are many expensive forms of insulation in the sandwich structure of a wall, adding one or other rigid insulation material, with a satisfactory result by computation but not always a sound solution in safety, health or environment. The best solution is to incorporate the thermal insulation into the concrete mix, as offered in air-cured CLC.
• Fire protection: The air incorporated in the CLC is also instrumental for high fire resistance. At a density of 1200 kg / m³, a wall 13-14 cm thick has a fire resistance of 5 hours. The same delay occurs with a layer of 400 kg / m³ of CLC in only 10 cm of thickness. CLC is otherwise non-combustible.
• Acoustic insulation: On the efforts to further increase the thermal capacity of building members, other aspects have been neglected, such as acoustic insulation. Sound is experienced as sound transmitted by the air or by the foot (impact). Airborne is a rule of density and therefore CLC offers superior protection to very lightweight concrete (ACC). Impact sound is superior to conventional concrete. Hitting a wall with a hammer, will allow you to feel the full force on the other side, while the air incorporated into CLC will not allow the blow to pass. At most it will suffer a small dent and thus avoid any major damage.
• Insulated Flooring: As impact force is not transmitted, slabs produced from CLC or covered with a CLC floorpan layer will prevent sound from being heard in the room below. CLC walls will also serve as sound retaining walls on roads or railways, thus absorbing the sound and preventing it from bouncing to the other side.
• Customizable physical properties: The addition of fibers to CLC is another important benefit, substantially increasing the bending stress and most of the impact resistance. Three-dimensional actuation fiber (eg polypropylene) will further reduce shrinkage, thereby reducing water absorption and increasing strength (up to 25%.) This is most appreciated when thin building components are produced.
• Economic Production: Using only lawn, cement, water and foam, the cost of a m³ of CLC in most cases is less than for the equivalent volume of conventional concrete. By adding all of the highly appreciated benefits described (including CLC) to regular concrete, if possible, the cost of such regular concrete would probably double but not yet reach the overall quality of the CLC.
