Composite autoclaved aerated concrete block based on coal-series solid waste and preparation method of composite autoclaved aerated concrete block
The invention discloses a composite autoclaved aerated concrete block based on coal-series solid waste and a preparation method of the composite autoclaved aerated concrete block, and belongs to the technical field of building wall materials, the aerated concrete block comprises the following raw materials by mass percentage: water, a dry material and an auxiliary material, the ratio of the water to the dry material is 0.52-0.65: 1; the dry materials comprise 20-30% of quick lime, 6-10% of carbide slag, 30-36% of fluidized bed combustion ash, 28-32% of coal-fired furnace slag, 6-8% of cement and 3% of gypsum; the auxiliary materials comprise 0.1% of aluminum powder and the balance of additives. The preparation method comprises the following steps: mixing and grinding raw materials according to a preset weight percentage, adding guar gum, and continuously grinding to obtain a mixture; adding the mixture, cement and gypsum, stirring, adding an additive, stirring, and adding aluminum powder to obtain slurry; injecting the slurry into a mold, and then performing pre-curing; and demolding and cutting are conducted, blank blocks are placed in a still kettle to be treated, the aerated concrete building blocks are obtained, and the technical effect of reducing the production cost is achieved.
本发明公开了一种基于煤系固废的复合蒸压加气混凝土砌块及其制备方法，属于建筑墙体材料技术领域，按照质量百分比计，加气混凝土砌块包括以下原料：水、干料和辅料，水和干料比为0.52～0.65:1；干料包括：20～30％生石灰、6～10％电石渣、30～36％固硫灰、28～32％燃煤炉渣、6～8％水泥、3％石膏；辅料包括0.1％铝粉和余量的外加剂。通过按照预定重量百分比，将原料混合研磨后，加入瓜尔胶继续研磨，获得混合料；将混合料、水泥、石膏加入搅拌，加外加剂搅拌，加铝粉获得浆料；将浆料注入模具中，之后进行预养护；进行脱模、切割，将胚块放置到蒸压釜处理，获得加气混凝土砌块，达到了降低生产成本的技术效果。
