Environment-friendly autoclaved aerated concrete block and preparation method thereof
The invention discloses an environment-friendly autoclaved aerated concrete block and a preparation method thereof.The block is prepared from, by mass, 100-180 parts of fly ash, 50-80 parts of regenerated brick powder, 40-60 parts of cement, 40-70 parts of lime, 20-40 parts of gypsum, 0.2-0.7 part of aluminum powder, 0.05-0.2 part of foam stabilizer and 200-300 parts of water. The preparation method comprises the steps that the fly ash, the regenerated brick powder, the cement, the lime and the gypsum are mixed to obtain a raw material mixture; mixing aluminum powder, a foam stabilizer and water to obtain an aluminum powder solution; mixing the raw material mixture with residual water to obtain mixed slurry A; mixing the aluminum powder solution with the mixed slurry A to obtain mixed slurry B; casting and molding the mixed slurry B, curing in a curing chamber, demolding and cutting to obtain a blank body; and performing autoclaved curing on the green body to obtain the building block. The recycled brick powder is added in the production of the aerated concrete, so that the resource utilization of waste clay bricks is realized, the cost of the aerated concrete is effectively reduced, and the strength, heat insulation, sound insulation and other properties of the aerated concrete block are improved by optimizing the ratio of the raw materials.
本发明公开了一种环保型蒸压加气混凝土砌块及其制备方法，砌块原料按质量份包括以下组分：粉煤灰100～180份、再生砖粉50～80份、水泥40～60份、石灰40～70份、石膏20～40份、铝粉0.2～0.7份、稳泡剂0.05～0.2份和水200～300份，制备方法为：粉煤灰、再生砖粉、水泥、石灰和石膏混合得原料混合物；铝粉、稳泡剂与水混合得铝粉溶液；原料混合物与剩余水混合得混合浆料A；铝粉溶液与混合浆料A混合得混合浆料B；混合浆料B浇注成型后在养护室中养护，脱模切割得胚体；坯体经蒸压养护即得上述砌块。本发明通过在加气混凝土生产中添加再生砖粉，不仅实现了废弃粘土砖的资源化利用，还有效降低了加气混凝土的成本，并通过优化原料配比提高了加气混凝土砌块的强度、保温隔热以及隔音等性能。
