Autoclaved aerated concrete and preparation method thereof
The invention discloses autoclaved aerated concrete, and relates to the technical field of autoclaved aerated concrete. The autoclaved aerated concrete comprises an outer surface layer, a connecting layer and a core layer; the outer surface layer is made of high-strength concrete, cellulose ether, redispersible polymer latex powder and an anti-cracking agent; the connecting layer is made of cement, quartz sand, ground calcium carbonate powder, redispersible polymer latex powder, cellulose ether and an anti-cracking agent; and the core layer is made of cement, fly ash, lime, gypsum, aluminum powder paste and waste slurry. The invention further provides a preparation method. The preparation method comprises the steps of preparing the outer surface layer concrete, the connecting layer concrete and the core layer concrete, then horizontally and uniformly filling the outer surface layer concrete, the connecting layer concrete and the core layer concrete into a mold, finally putting the moldinto an autoclave room for autoclaving and aerating, and demolding after curing. The autoclaved aerated concrete provided by the invention retains the good light weight, mechanical strength and frostresistance of traditional autoclaved aerated concrete, and also greatly improves the waterproof ability, so that the autoclaved aerated concrete has wider applicability.
本发明公开一种蒸压加气混凝土，涉及蒸压加气混凝土技术领域，包括外表层、连接层和芯层，外表层的材料包括高强混凝土、纤维素醚、可再分散聚合物乳胶粉和抗裂剂，连接层的材料包括水泥、石英砂、重钙粉、可再分散聚合物乳胶粉、纤维素醚和抗裂剂，芯层的材料包括水泥、粉煤灰、石灰、石膏、铝粉膏和废料浆；本发明还提供了制备方法，通过配制外表层混凝土、连接层混凝土、芯层混凝土，接着往模具中水平均匀填充外表层混凝土、连接层混凝土、芯层混凝土，最后将模具放入蒸压房进行蒸压加气，固化后脱模。本发明保留了传统的蒸压加气混凝土具有较好的轻质性、机械强度和抗冻性的同时，大幅提高了防水能力，使蒸压加气混凝土拥有更广阔的适用性。
