An Overview on AAC Block Manufacturing Process After the autoclaving process the material is ready for immediate use on the construction site Depending on its density up to 80% of the volume of an AAC block is air AAC s low density also accounts for its low structural compression strength It can carry loads of up to 8 MPa 1160 PSI

The density of regular concrete is normally measured at 2400 kg/m³ whereas the density of the foamed concrete ranges from 400 kg/m 3 to 1 800 kg/m 3 The density of cellular lightweight concrete can be effectively determined by introducing foam formed utilizing a foam generator Using fly ash based CLC lowers the density but it has absolutely no effect on the overall strength of the structures
