May 14, 2020 · ABC of AAC Autoclaving. May 14, 2020. The primary purpose of the Autoclaving is to transform the green cake into white cake. This transformation takes place in autoclaves, where the green cakes are left for curing. The actual curing takes place by filling the autoclave with pressurised steam (saturated water vapour) supplied by the boiler.
