High silicon iron tailing autoclaved aerated concrete slab and preparation method thereof
The invention relates to the technical field of building materials, in particular to a high-silicon iron tailing autoclaved aerated concrete slab and a preparation method thereof. The high-silicon iron tailing autoclaved aerated concrete slab comprises the following components in percentage by weight: 40-45% of iron tailings, 4.5-5.5% of fly ash, 5.0-6.0% of lime, 9.0-10.0% of cement, 2.5-3.5% of glass slag, 1.0-1.5% of gypsum, 0.04-0.06% of aluminum powder, 0.02-0.03% of graphene and 30-35% of water. The preparation method comprises the following steps: (1) preparing slurry; (2) processing reinforcing steel bars and assembling a mesh cage; (3) conducting pouring; (4) performing foaming and standing; and (5) carrying out autoclaved curing. The high silicon iron tailing autoclaved aerated concrete slab is low in cost, high in strength, strong in durability, good in thermal insulation performance and low in volume weight.
本发明涉及建筑材料技术领域，尤其涉及一种高硅铁尾矿蒸压加气混凝土板及其制备方法，以重量百分比计，包括：铁尾矿40～45%，粉煤灰4.5～5.5%，白灰5.0～6.0%，水泥9.0～10.0%，玻璃渣2.5%~3.5%；石膏1.0～1.5%，铝粉0.04～0.06%，石墨烯0.02～0.03%，水30～35%。制备方法包括：（1）料浆配制；（2）钢筋加工及网笼组装；（3）浇注；（4）发泡静养；（5）蒸压养护。本发明高硅铁尾矿蒸压加气混凝土板成本低廉、强度高、耐久性强、保温隔热性能好、容重低。
