Aerated Concrete
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.
