Aerated Concrete - an overview | ScienceDirect …
Autoclaved aerated concrete is a porous concrete used widely in several countries. The adhesive material of it is cement or lime powder, fly ash, mixed with fine sand or slag and water. In the meantime, the foaming agent is put into the liquid and numerous stable bubbles of diameter 1–2 mm are produced, and the uniform porosity is formed. After the liquid is left for several hours and then ...

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 ...

01.01.2019 · Autoclaved aerated concrete (AAC), a form of cellular concrete, is a low-density cementitious product of calcium silicate hydrates in which the low density is obtained by the formation of macroscopic air bubbles, mainly by stone reactions within the mass during the liquid or stone phase. The air bubbles are uniformly distributed and are retained in the matrix on setting, hardening, and ...
