Autoclaved aerated concrete slab and preparation method thereof
The invention discloses an autoclaved aerated concrete slab and a preparation method thereof. The autoclaved aerated concrete slab is composed of a base material and a steel bar net or a steel bar framework embedded in the base material, wherein the base material is prepared from Portland cement, quicklime powder, a siliceous material, desulfurized gypsum and water-based aluminum paste, the siliceous material is prepared from quartz beneficiation waste mud and furnace slag, and the preparation method comprises the following steps: 1) adding water into the quartz beneficiation waste mud and thefurnace slag to prepare mixed slurry, and adding water into the desulfurized gypsum to prepare desulfurized gypsum slurry; 2) uniformly mixing the mixed slurry, the desulfurized gypsum slurry, quicklime powder, Portland cement, water-based aluminum paste and water, pouring into a mold, fixing the steel bar net or the steel bar framework in the mold, and standing for hardening to obtain a green body; and 3) releasing the green body from the mold, cutting, and maintaining under autoclave. The autoclaved aerated concrete slab disclosed by the invention is high in strength, large in bearing capacity, good in durability, good in heat-insulating property, reduced in drying loss and low in production cost.
本发明公开了一种蒸压加气混凝土板及其制备方法。本发明的蒸压加气混凝土板由基体材料和埋设在基体材料中的钢筋网或钢筋骨架组成，所述基体材料由硅酸盐水泥、生石灰粉、硅质材料、脱硫石膏和水性铝膏制成，硅质材料由石英选矿废泥和炉渣组成，其制备方法包括以下步骤：1)将石英选矿废泥和炉渣加水制成混合料浆，并将脱硫石膏加水制成脱硫石膏浆；2)将混合料浆、脱硫石膏浆、生石灰粉、硅酸盐水泥、水性铝膏和水混匀后浇注入模具，再将钢筋网或钢筋骨架固定在模具中，静置硬化，得到坯体；3)将坯体从模具中脱出，切割，蒸压养护。本发明的蒸压加气混凝土板的强度高、承载能力大、耐久性好、隔热性能好、干燥収缩小，且生产成本低。
