A comprehensive study on the production of autoclaved aerated concrete
Finer quartz is more reactive than coarser quartz, but it also promotes the formation of gyrolite, an undesirable mineral in AAC. Zhao et al. [23] noted that the tobermorite gradually transformed to xonotlite with continuous autoclaving, a finding which suggests that immoderate autoclave curing may harm the properties of AAC.
