Autoclaved aerated concrete containing coal gangue and iron tailings and preparation method of autoclaved aerated concrete
The invention belongs to the technical field of building wall materials, and particularly relates to autoclaved aerated concrete containing coal gangue and iron tailings and a preparation method of the autoclaved aerated concrete. The autoclaved aerated concrete containing the coal gangue and the iron tailings is prepared from the following raw materials in parts by weight: 5 to 30 parts of the coal gangue, 15 to 25 parts of aluminum slag, 30 to 55 parts of the iron tailings, 5 to 15 parts of nanoscale silicon dioxide, 5 to 15 parts of metakaolin, 10 to 15 parts of quick lime, 0 to 5 parts of cement and the balance of waste materials. Auxiliary materials include aluminum powder, a foam stabilizer and a water reducing agent. In the raw materials, the iron tailings and the coal gangue are used as siliceous materials, so that the environmental problem caused by solid waste stockpiling can be solved, waste is turned into wealth, and meanwhile, a good effect is achieved on the sustainable development of the society. The prepared concrete block has good physical and mechanical properties and durability, the product performance meets the national standard requirement, and 04-grade, 05-grade, 06-grade and 07-grade concrete blocks can be produced according to different proportions and process systems.
本发明属于建筑墙体材料技术领域，具体涉及一种含煤矸石、铁尾矿的蒸压加气混凝土及其制备方法。一种含煤矸石、铁尾矿的蒸压加气混凝土，包括以下重量份原料：煤矸石5～30份，铝渣15～25份，铁尾矿30～55份，纳米级二氧化硅5～15份，偏高岭土5～15份，生石灰10～15份，水泥0～5份，余量为废料，辅料：铝粉、稳泡剂和减水剂。本发原料中以铁尾矿和煤矸石为硅质材料，可以解决固废堆存所引起的环境问题，实现变废为宝，同时对社会的可持续发展起到良好的效应。制备所得的混凝土砌块具有良好的物理力学性能和耐久性，产品性能满足国标要求，可根据不同配比及工艺制度生产04级、05级、06级、07级混凝土砌块。
