Aerated concrete block and preparation method thereof
The invention provides an aerated concrete block and a preparation method thereof. The aerated concrete block is prepared from the following raw materials in percentage by weight: 58 to 74 percent of fly ash aluminum extraction residues, 2 to 3 percent of gypsum, 7 to 14 percent of cement, 16 to 29 percent of quick lime and 0.05 to 0.08 percent of aluminum powder paste. The characteristics of the fly ash aluminum extraction residues are fully utilized, and the fly ash aluminum extraction residues are cooperated with other raw material components with specific contents, so that the obtained aerated concrete block is high in compressive strength, small in dry density, low in cost, excellent in comprehensive performance and suitable for wide popularization and utilization.
本发明提供了一种加气混凝土砌块及其制备方法。按重量百分比计，加气混凝土砌块的原料包括58～74％的粉煤灰提铝残渣、2～3％的石膏、7～14％的水泥、16～29％的生石灰及0.05～0.08％的铝粉膏。本发明充分利用粉煤灰提铝残渣的特性，并与其它特定含量的原料组分协同，得到的加气混凝土砌块抗压强度高、干密度小，成本低，综合性能优异，适合于广泛推广利用。
