We are supplier of AAC block production line To manufacture aerated autoclaved brick, cement is mixed with lime, silica sand or recycled fly ash, water, and aluminum powder or paste. Material slurry can be held in the combination of the mould and the side plates, after setting, curing and foaming, it can be solidified into the blank, the side plate can bear the blank which shall be cut by the cutting machinery, and fed into the autoclave to be hardened together with the hardening car. The slurry is poured into moulds where a chemical reaction occurs, the reaction between aluminum and concrete causes hydrogen in the mould for 45minutes, the high closed porous aac unit is cut to size and formed by steam-curing in autoclave for 6-8hours. The result is a non-toxic, airtight material that can be used for wall, floor and roof panels, blocks. With abundant air cells and porous unit inside the aerated brick, it has good performance of heat insulation and preservation. In addition, the most prominent advantage is its plasticity. Due to the lightness and the lower hardness, aac units are available in numerous shapes and sizes according to the real construction usages and customer's requirements. Product weight is according to 600kg/m3 to control.raw material: cement, lime, fly ash or cement, lime, sand.
