CLC is called as Cellular Light Weight Concrete and it is also called as Foam Concrete. Cellular Light Weight Concrete (CLC) is a version of light weight concrete that is produced like normal concrete under ambient conditions. CLC Blocks are a cement-bonded material made by blending slurry of cement. Stable, pre-formed foam manufactured on site is injected into this slurry to form foam concrete. Fresh foam concrete looks like a milk- shake and the volume of slurry in the foam dictates the cast density of the foam concrete.
