Lightweight concrete, usually in the form of blocks. AAC has a low density due to the inclusion of large numbers of air cells, typically 1mm –5mm across. Produced in an autoclave at high pressure and temperature. Materials used in AAC production are typically cement and lime as the binder, with sand or pulverized fuel ash (PFA) as the source of silica.
