Argil tailing autoclaved aerated concrete block and preparing method thereof
The invention discloses an argil tailing autoclaved aerated concrete block. The argil tailing autoclaved aerated concrete block is prepared from 32 parts of argil tailings, 15 parts of quartz sand slag, 5 parts of blast furnace slag, 5 parts of petroleum wax, 16 parts of lime, 12 parts of vermiculite power, 5 parts of cement, 1 part of aluminum powder paste, 3 parts of shells, 2 parts of disodium hydrogen phosphate and 4 parts of sodium silicate. Compared with the prior art, the argil tailing autoclaved aerated concrete block has the following advantages that the argil tailings are modified through sodium hydroxide and then used in preparation of the argil tailing autoclaved aerated concrete block, fireproof performance and weather resistance of the argil tailing autoclaved aerated concrete block can be effectively improved, the service life of the argil tailing autoclaved aerated concrete block is prolonged, the water absorption rate can reach 8.52-9.83%, the shrinking percentage is only 0.5-0.8 mm/m, cracks caused by dryness can be avoided, industrial waste is effectively used, and environment pollution is reduced.
