NEOPOR® CLC

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 offeres 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.

For structural (steel-reinforced) application, CLC is used in densities of 1.200 to 1.400 kg/m³, which, due to the billion of microsized and uniform air bubbles offer 500 % (!) more thermal insulation and a substantialy 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 also use 10 times more material (sand, gravel, cement) to produce. In 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.
