LightWeight Concrete

CLC (Cellular Lightweight Concrete):

•       Foam concrete is cellular material made with a mixture of cement, Fly ash, and sand (optional), stable Foam and special additives (if required) which will help to form unique cellular structure material.
•  The hardened material consists of small enclosed air bubbles thereby resulting in a lightweight stable cellular material with densities ranging from 400kg/m3 to 1800kg/m3 according to various compositions. Foam concrete manufacturing consumes higher amounts of fly ash hence it is considered as green building material.
•  The Basic foam concrete is made from mixing aqua’s which is produced from foam generator into slurry of cement, fly ash, sand (optional) water and other additives in a precisely specially designed mixer for accurately mixing without disturbing its original chemical and physical properties.
•  The final mixture results in many small cells uniformly distributed throughout the concrete which will create cellular structural material from densities ranging from 400kg/m3 to 1800kg/m3.
•  The precise control of volume of air cell in foam will result controlled densities and strengths of foam concrete.
• The use of Cellular Lightweight Concrete masonry will result in cheaper and faster construction compared with framed building construction for low-rise buildings.

                                                 Advantages of CLC

• —            Savings in Raw Material: The tremendous savings described when using CLC are manifold, continuing with substantial savings in raw material (no gravel required), in dead load of high-rise reducing by almost half. Considering that a substantial amount of steel is necessary only to carry the weight of the structure, steel requirement might reduce by hundreds of ton in high rise.
•              Considerably Lower Weight: Weight reduction is obvious in transport, where almost double of volume of building material can be produced; it has an impact on craning, where either larger panel can be taken, or the full Capacity in span. Alternatively less re-location of the crane is necessary.
•             Thermal Insulation: Thermal Insulation increasingly turns to be the most important issue in the planning and construction of buildings. There are many costly ways of insulation on sandwich structure of a wall, adding the one or another rigid insulation material, with a satisfactory result by computation but not always a sound solution in safety, health or environment.
•      —  Fire Protection: The air-embedded in the CLC is also instrumental for the high fire-rating. In 1200 kg/m³ density a 13-14 cm thick wall has a fire endurance of 5 hours. The same delay occurs with a 400 kg/m³ layer of CLC in only 10 cm thickness. CLC is otherwise non-combustible.
•       Sound Insulation: Over the efforts to keep on increasing the thermal capacity of building members, other aspects have been neglected, such as sound insulation. Sound is experienced as air-borne or foot-fall sound (impact). Air-borne it is a rule of density and therefore CLC offers superior protection than very light concrete (ACC). In impact sound it is superior to conventional concrete. Hitting a wall with a hammer, will let you feel the full force on the other side, whilst the air embedded in CLC will not allow the blow to pass through.
•      Insulated Flooring: As the impact force will not transmit, slabs produced of CLC or topped with a layer of CLC floor screen will prevent any sound being noticed in the room below. Walls of CLC will also serve as sound retaining walls on roads or railway tracks therefore, absorbing the sound and preventing it from bouncing to the other side.
•      Customizable Physical Properties: Adding fibers to CLC is a further important benefit, increasing bending stress substantially and most of it impact strength. The three dimensional acting fiber (e.g. polypropylene) will further reduce shrinkage, therefore reducing water absorption and increasing strength (up to 25 %. This is appreciated most when producing slender building components.
•     —   Economical Production: Using only fly ash, cement, water and foam, the cost for one m³ of CLC in most cases is less even than for the equivalent volume of conventional concrete. Adding all the described highly appreciated benefits (comprising CLC) to regular concrete, if at all possible, the cost for such regular concrete would probably double but still not reach the overall quality of CLC.
