Aerated concrete and preparation method thereof
The invention is suitable for the technical field of concrete, and provides aerated concrete and a preparation method thereof. The aerated concrete comprises the following raw materials in percentage by weight: 10-20% of sand, 10-20% of fly ash, 20-32% of cement, 5-15% of mortar, 0.1-2% of aluminum powder or aluminum powder paste, 1-6% of quick lime, 0.5-1.4% of gypsum, 1-5% of stone powder, 8-15% of straw carbon, 0.5-3% of magnesia and the balance of water. By improving the components of the aerated concrete and the preparation method of the aerated concrete, the problems of corner cracks, horizontal cracks, vertical fractures, steam-curing cracks and the like are not prone to being generated in the cutting process of the aerated concrete, and the prepared aerated concrete is good in quality and free of the situations of corner cracks, horizontal cracks, vertical fractures, steam-curing cracks and the like; the preparation method is simple and convenient for industrial production.
本发明适用于混凝土技术领域，提供了一种加气混凝土及其制备方法。加气混凝土包括以下重量百分数的原料：砂料10~20%、粉煤灰10~20%、水泥20~32%、砂浆5~15%、铝粉或铝粉膏0.1~2%、生石灰1~6%、石膏0.5~1.4%、石粉1~5%、秸秆炭8~15%、菱苦土0.5~3%，余量为水。本发明通过改进加气混凝土组分及其制备方法，加气混凝土在切割过程中不容易产生边角裂、水平裂、垂直断裂、蒸养裂等问题，制备得到的加气混凝土质量好，无边角裂、水平裂、垂直断裂、蒸养裂等情况；制备方法简单，便于工业化生产。
