Aerated concrete block and preparation method thereof
The invention discloses an aerated concrete block and a preparation method thereof, and relates to the technical field of building materials. The aerated concrete block comprises the following components in parts by weight: 180-220 parts of cement; 150-200 parts of lime; 200-250 parts of fly ash; 25-35 parts of desulfurized gypsum; 0.9-1.1 parts of aluminum powder; 350-400 parts of carbonized ricehull powder; 5-10 parts of methyl sodium silicate; and 500-600 parts of water. The preparation method comprises the following steps: S1, uniformly mixing the cement, the lime, the fly ash, the gypsum, the aluminum powder, the carbonized rice hull powder and the sodium methyl silicate according to a raw material ratio; S2, sequentially adding water and aluminum powder into the mixture obtained inthe step S1, uniformly stirring, pouring the slurry into a mold, standing the mold in an environment with the temperature of 22 +/-2 DEG C and the humidity of 60 +/-10% for 3-4 hours, demolding, and cutting according to requirements; and S3, putting the cut building block into a 60-80 DEG C autoclave, carrying out steam curing for 10-12 hours, cooling to room temperature, and standing for 7 days in a standard environment to obtain the building block. The aerated concrete block prepared by the invention has the advantages of light weight, high strength and good water resistance.
本申请公开了一种加气混凝土砌块及其制备方法，涉及建筑材料技术领域。该加气混凝土砌块，包括水泥180‑220份；石灰150‑200份；粉煤灰200‑250份；脱硫石膏25‑35份；铝粉0.9‑1.1份；碳化稻壳粉350‑400份；甲基硅酸钠5‑10份；水500‑600份。其制备方法为：S1，按原料配比将水泥、石灰、粉煤灰、石膏、铝粉、碳化稻壳粉和甲基硅酸钠混合均匀；S2，依次在步骤S1得到的混合物中加入水和铝粉，搅拌均匀后，将浆料倒入模具中，将模具于22±2℃、湿度60±10%环境下静置3‑4h，脱模并按要求切割；S3，将切割后的砌块置于60‑80℃蒸压釜中进行蒸汽养护10‑12h，然后降至室温，并于标准环境下静置7d，即得。本申请制备的加气混凝土砌块具有轻质、强度高和耐水性好的优点。
