High-volume tailing autoclaved aerated concrete and preparation method thereof
The invention specifically discloses high-volume tailing autoclaved aerated concrete, which is mainly prepared from the following raw materials: 50 to 60 parts of tailing powder, 0 to 20 parts of quartz sand, 10 to 20 parts of cement, 0 to 20 parts of admixture, 10 to 30 parts of quick lime, 5 to 10 parts of gypsum, 0.1 to 0.2 part of gas forming material, 0.1 to 0.2 part of water reducing agent and 50 to 60 parts of water, the tailing powder comprises one or more of tungsten tailings, gold tailings and quartz tailings; the admixture comprises one or more of silica fume, zirconium silica fume, fly ash sinking beads, fly ash floating beads and nano calcium carbonate; the gas forming material is aluminum powder; according to the present invention, the tailing is adopted to replace the sand during the preparation of the autoclaved aerated concrete, the doping amount of the tailing is improved through the technical optimization, the performance and the quality of the tailing are ensured, and the manufacturing cost of the autoclaved aerated concrete is reduced; and environmental pollution and land resource waste caused by tailing accumulation are reduced.
本发明具体公开了一种高掺量尾矿蒸压加气混凝土，主要包括以下原料：50‑60份尾矿粉料、0‑20份石英砂、10‑20份水泥、0‑20份掺合料、10‑30份生石灰、5‑10份石膏、0.1‑0.2发气材料、0.1‑0.2份减水剂、50‑60份水；所述尾矿粉料包括钨尾矿、金尾矿、石英尾矿中的一种或多种；所述掺合料包括硅灰、锆硅灰、粉煤灰沉珠、粉煤灰飘珠、纳米碳酸钙中的一种或多种；所述发气材料为铝粉；通过加入铝粉产生氢气，经过压蒸工艺制备而得，在制备蒸压加气混凝土时通过将尾矿取代砂，同时通过技术优化提高尾矿的掺量，同时保证其性能和品质，降低蒸压加气混凝土的制造成本，减少环境污染和因为尾矿堆积造成的土地资源的浪费。
