The block is composed of the following raw materials comprising, by weight, 22-24 parts of cement, 14-16 parts of quicklime, 12-14 parts of gypsum, 20-25 parts of fly ash, 0.1-0.2 parts of aluminium powder, 30-35 parts of iron sand tailings, 12-15 parts of calcium chloride, 1-2 parts ofberyllia, 3-5 parts of sulfamate water reducing agents, 3-5 parts of zinc oxide, 2-3 parts of tributyl phosphate, 1-2 parts of dodecyl betaine, 3-5 parts of sodium persulfate, 2-3 parts of oil foot, 2-3 parts of silane coupling agent KH5502, 2-3 parts of cross-linking agent TAC and 6-8 parts of sodium tripolyphosphate. The aerated concrete block is advantaged by high compressive strength, light weight, sound insulation, heat insulation, good heat retaining property, good anti-frost property, less contraction and the like. The aerated concrete block overcomes the defects of low strength and easy cracking of traditional aerated concrete blocks. Beryllia in the block is a good refractory material and can be fire-retardant.
