What is Cellular Concrete?

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 biodegradable foam that offers no chemical reaction but solely serves as wrapping 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.

For structural (steel reinforced) application, CLC is used in densities of 1,200 to 1,400 kg/m³, which, due to the billion of micro sized and uniform air bubbles offers 500% more thermal insulation and substantially higher fire rating than conventional concrete. If a wall of conventional concrete should offer the same thermal insulation as CLC, the wall produced would have to measure 5 times thicker and therefore use 10 times more materials (sand, gravel, cement) to produce. In a hot environment, the essential air conditioning requires 500% more primary energy to cool down than when heating, a fact, which is not even known to many experts. CLC is also an environmentally friendly material.
