Autoclaved aerated concrete, autoclaved aerated concrete slab and preparation method thereof
The invention provides autoclaved aerated concrete, an autoclaved aerated concrete slab and a preparation method of the autoclaved aerated concrete slab. The autoclaved aerated concrete is prepared from 55%-70% of a siliceous material, 10%-20% of cement, 10%-20% of quick lime, 2%-8% of desulfurized gypsum, 0.1%-0.12% of aluminum powder paste or dry aluminum powder and 0.1%-0.3% of magnesia. An autoclaved aerated concrete slab is made of concrete. The preparation method of the autoclaved aerated concrete slab comprises the following steps: mixing the raw materials with water to prepare pouringslurry, pouring the pouring slurry into a mold box, inserting a reinforcing mesh into the mold box, and carrying out static curing; after the strength is reached, demolding and cutting the material, and then pre-curing the material; and carrying out steam curing on the pre-cured concrete slab, and carrying out post-treatment to obtain the autoclaved aerated concrete slab. The autoclaved aerated concrete slab prepared from the concrete provided by the invention has the advantages of low cement consumption, high strength, no cracking and low cost.
本发明提供一种蒸压加气混凝土、蒸压加气混凝土板及其制备方法。蒸压加气混凝土：硅质材料55‑70％、水泥10‑20％、生石灰10‑20％、脱硫石膏2‑8％、铝粉膏或干铝粉0.1‑0.12％和菱苦土0.1‑0.3％。蒸压加气混凝土板，使用混凝土制成。蒸压加气混凝土板的制备方法：将原料与水混合制备得到浇注料浆，然后将浇注料浆浇注至模箱中，再向模箱内插入钢筋网片，然后进行静养养护；达到强度后对其进行脱模、切割，然后进行预养护；将经过预养护的混凝土板进行蒸养，进行后处理得到蒸压加气混凝土板。本申请提供的混凝土制得的蒸压加气混凝土板，水泥用量少，强度高、不开裂，成本低。
