High-performance autoclaved aerated concrete material prepared from tailings and preparation method of high-performance autoclaved aerated concrete material
The invention discloses a high-performance autoclaved aerated concrete material prepared from tailings and a preparation method of the high-performance autoclaved aerated concrete material. The concrete material comprises the components: 15-25% of cement, 50-65% of tailing sand, 0.5-1% of nano calcium carbonate, 2-7% of gypsum, 0.15-0.2% of aluminum powder, 1-5% of high-strength ceramsite, 2-5% of a water reducing agent and water. The autoclaved aerated concrete is prepared by taking the cement, the tailing sand and the gypsum as basic raw materials and the aluminum powder as a foaming agent, pouring forming, standing, pre-curing, autoclaved curing and the like, so that the autoclaved aerated concrete is light and porous concrete, has the performance characteristics of small heat conductivity coefficient, good fire resistance, processability and the like, and can be widely applied to internal and external wall materials.
本发明公开了一种利用尾矿制备高性能蒸压加气混凝土材料及其制备方法，其混凝土的材料的配比为：水泥15‑25%、尾矿砂50‑65%、纳米碳酸钙0.5‑1%、石膏2‑7%、铝粉0.15‑0.2%、高强陶粒1‑5%、减水剂2‑5%以及水组成。本发明蒸压加气混凝土由水泥、尾矿砂、石膏为基本原料，铝粉为发气剂进行浇筑成型、静停、预养、蒸压养护等步骤制成的蒸压加气混凝土具有轻质、多孔混凝土，具有导热系数小、耐火性能好，可加工等性能特点，可以被大量应用与内外墙体材料。
