Airolite CLC Blocks

Cellular Lightweight Concrete (CLC) is conventional concrete, where natural aggregate (gravel) is exchanged for the best insulation medium available, namely air, embedded in an organic and bio-degradable foam that offers no chemical reaction but solely serves as wrapping material for the air. Consequently CLC behaves, like conventional concrete, in particular concerning curing, hardening and most important “ageing “. CLC infinitely increases its strength by hydration (forming of crystals in cement) as long as exposed to humidity in the atmosphere.

CLC is a process based on making air bubbles in the form of a foam and then mixing the foam into a cement / flyash slurry. The slurry is then poured into moulds. Since CLC slurries have higher cement contents, no autoclave curing is required – instead, the finished product is cured like normal concrete or Steamed Cured with low pressure to achieve early strength. CLC air bubbles are significantly smaller, stronger, and each bubble is part of a closed cell system – which means Airolite CLC block products have lower water absorption and it is very useful in heavy rainfall areas. CLC blocks increase in strength when exposed to moisture. Hence CLC bricks become tougher over time.

Airolite CLC blocks are available in different sizes like 600 mm (L) 100-300 mm (W) 240/200 mm (H) and also in custom size depending upon the quantity. The detailed technical specifications are available on website
