Aerated concrete block production process
The invention relates to the field of building engineering materials, in particular to an aerated concrete block production process. Low-density, high-compressive-strength and high-standard-performance aerated concrete blocks are manufactured specifically with quartz sand tailings as main raw materials by adding lime powder, gypsum powder, cement, foaming agents, foam stabilizer, water and the like and conducting the following steps of material preparing, material mixing, stirring, pouring, hot chamber initial setting, blank body cutting, hot chamber standing, microwave autoclaved curing and the like, wherein the grain size of the quartz sand tailings is smaller than 0.125 mm, and by mass, 350 parts to 500 parts of fine quartz tailing powder, 80 parts to 150 parts of lime powder, 20 parts to 30 parts of gypsum powder, 30 parts to 40 parts of cement, 0.3 part to 0.5 part of foaming agents, 0.04 part to 0.06 part of foam stabilizer and 200 parts to 300 parts of water are used. The fine quartz tailing powder with the grain size smaller than 0.125 mm is used as the main silica raw material, waste is used, and the production cost of the aerated concrete blocks is reduced.
