Method for preparing autoclaved aerated concrete block by using geopolymer
The invention relates to the technical field of autoclaved aerated concrete block production processes, in particular to a method for preparing an autoclaved aerated concrete block by using a geopolymer. The cement mixing amount in the autoclaved aerated concrete block can be reduced by utilizing the geopolymer, and the cement mass is reduced to 0.3-0.4% from the original 5-6%; the mold collapse phenomenon in the slurry gas forming process can be effectively reduced, the slurry setting time is shortened, the standing time is shortened, and the production efficiency is improved; the raw materials for preparing the geopolymer are wide in source and rich in reserves, a low-temperature polymerization curing reaction can occur through the polycondensation action of the geopolysilicate precursor, the main raw materials of the geopolymer are aluminosilicate minerals such as metakaolinite and industrial waste such as fly ash and blast furnace slag, and environmental protection is facilitated.
本发明涉及蒸压加气混凝土砌块生产工艺技术领域，具体为一种利用地质聚合物制备蒸压加气混凝土砌块的方法。利用地质聚合物可降低蒸压加气混凝土砌块中的水泥掺量，水泥质量由原来的5～6%降低至0.3～0.4%；能有效降低浆料发气过程中的塌模现象，缩短浆料凝结时间，缩短静停时间提高生产效率；制备地质聚合物的原料来源广泛、储量丰富，通过地聚硅酸盐前体的缩聚作用，可以发生低温聚合固化反应，地质聚合物的主要原料为偏高岭石等铝硅酸盐矿物以及粉煤灰、高炉炉渣等工业废料，利于环保。
