Production of autoclaved aerated concrete with silica
The main components used to produce AAC are silica sand as a SiO 2 source, lime, and cement as a CaO source, and a small amount of aluminium powder or paste as a pore-forming agent [10]. However, almost all of the current produced AAC contains sulfate carriers (i.e. gypsum and anhydrite) as well.
