Autoclaved aerated concrete block and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses an autoclaved aerated concrete block and a preparation method thereof. The autoclaved aerated concrete block is prepared from the following components in parts by weight: 130 to 150 parts of lime, 30 to 40 parts of desulfurized gypsum, 160 to 200 parts of cement, 220 to 250 parts of glass micro powder, 0.75 to 0.95 part of aluminum powder, 130 to 150 parts of rice hull ash and 500 to 600 parts of water, the rice hull ash is prepared by the following steps: soaking rice hulls in hydrochloric acid, filtering, drying, roasting, and grinding after roasting to obtain the rice hull ash; the roasting temperature curve is as follows: roasting for 1 hour at the temperature of 580 DEG C, heating to 600 DEG C at the rate of 1 DEG C/min, and preserving heat and roasting for 1 hour. According to the autoclaved aerated concrete block prepared by the invention, the waste material is used for replacing stone powder as a main material, so that the problem of shortage of stone powder resources can be solved, the recycling of the waste material is improved, and the prepared autoclaved aerated concrete has relatively high strength and stability and relatively low dry density.
本申请涉及建筑材料技术领域，具体公开了一种蒸压加气混凝土砌块及其制备方法。该蒸压加气混凝土砌块包括如下重量份数的组分：石灰130‑150份、脱硫石膏30‑40份、水泥160‑200份、玻璃微粉220‑250份、铝粉0.75‑0.95份、稻壳灰130‑150份、水500‑600份；所述稻壳灰由如下制备步骤制备得到：将稻壳置于盐酸中浸泡，过滤干燥后进行焙烧，焙烧之后进行研磨，得到稻壳灰；所述焙烧的温度曲线为：先在580℃下焙烧1h，再以1℃/min的速率升温至600℃，并保温焙烧1h。本申请制备的蒸压加气混凝土砌块采用废弃材料替代石粉作为主要材料，不仅能够解决石粉资源短缺的问题、提高废弃材料的循环再利用，且制备的蒸压加气混凝土具有较高的强度、稳定性和相对较低的干密度。
