Autoclaved aerated concrete YourHome

Autoclaved aerated concrete, or AAC, is concrete that has been manufactured to contain lots of closed air pockets. Lightweight and fairly energy efficient, it is produced by adding a foaming agent to concrete in a mould, then wire-cutting blocks or panels from the resulting 'cake' and 'cooking' them with steam (autoclaving). The popularity of AAC in Australia has grown since its
