Aerated concrete and preparation method thereof
The invention belongs to the field of building materials, and discloses aerated concrete and a preparation method thereof. The aerated concrete is characterized by comprising the following componentsin percentage by weight: 60%-74% of fly ash, 15%-29% of slag, 0.8%-1.0% of a foam stabilizer, 2.0%-4.9% of a regulator, 1.0%-2.4% of a gas forming agent and an activator solution with a weight ratio of H2O to Na2O being 6-8.8, wherein the fly ash is commercially-available I-grade low-calcium fly ash, and the slag is commercially-available S95-grade mineral powder. According to the alkali-activatedaerated concrete provided by the invention, the fly ash and the slag are used as main raw materials, industrial-grade liquid water glass is used as an activator, and industrial-grade hydrogen peroxide is used as the gas-forming agent, so the aerated concrete has the advantages of simple process and low cost, red mud which is solid waste difficult to utilize in the metallurgical industry can be recycled, and remarkable economic benefits and social benefits are obtained.
本发明本发明属于建筑材料领域，公开了一种加气混凝土及其制备方法，一种加气混凝土，其特征在于，包括占粉体原料重量60％～74％的粉煤灰、15％～29％的矿渣、0.8％～1.0％的稳泡剂、2.0％～4.9％的调整剂、1.0％～2.4％的发气剂以及H2O/Na2O重量比6～8.8的激发剂溶液；所述的粉煤灰为市售I级低钙粉煤灰，所述的矿渣为市售S95级矿粉：本发明提供的碱激发加气混凝土以粉煤灰、矿渣为主要原料，以工业级液体水玻璃为激发剂，以工业级双氧水为发气剂，具有工艺简单、成本低廉的优点，且可资源化利用赤泥这一难利用冶金工业固废，具有显著的经济效益和社会效益。
