Autoclaved aerated concrete synergistically prepared from all solid wastes and preparation method of autoclaved aerated concrete
The invention relates to autoclaved aerated concrete prepared from all solid wastes synergistically and a preparation method of the autoclaved aerated concrete. The aerated concrete is characterized by being prepared from the following components in parts by mass: 30 to 80 parts of industrial byproduct building gypsum powder, 0 to 30 parts of industrial byproduct gypsum powder, 5 to 40 parts of carbide slag, 10 to 55 parts of lithium slag, 0.5 to 2 parts of a water reducing agent, 0 to 1 part of a retarder, 0.5 to 2 parts of cellulose ether, 0.05 to 1 part of an air entraining agent, 0.002 to 0.05 part of aluminum powder and 30 to 60 parts of water. The preparation method comprises the following steps: uniformly stirring industrial byproduct building gypsum powder, carbide slag and lithium slag according to a certain ratio, adding water and an additive, finally adding aluminum powder and cellulose ether for foaming, standing for 4-6 hours, cutting, feeding into an autoclave for autoclaved curing, taking out of the autoclave, and stacking for curing for 7 days. According to the invention, physicochemical properties of industrial by-products are fully utilized and mutually stimulated to generate gelling property, and meanwhile, secondary hydration is promoted by adopting an autoclaved curing process to enhance a microstructure, so that the high-performance aerated concrete is prepared and has good economic benefits, environmental benefits and social benefits.
一种全固废协同制备的蒸压加气混凝土及其制备方法，其特征在于所述加气混凝土由下述质量份组成：30‑80份工业副产建筑石膏粉、0‑30份工业副产石膏粉、5‑40份电石渣、10‑55份锂渣、0.5‑2份减水剂、0‑1份缓凝剂、0.5‑2份纤维素醚、0.05‑1份引气剂、0.002‑0.05份铝粉、30‑60份水组成。将工业副产建筑石膏粉、电石渣、锂渣按照一定比例搅拌均匀后，加入水与添加剂，最后加入铝粉与纤维素醚发泡，经静停4‑6小时后切割，送入蒸压釜进行蒸压养护，出釜后码垛养护至7天即可。本发明充分利用工业副产物的理化性质，相互激发产生胶凝性，同时采用蒸压养护工艺促使二次水化增强微结构，制备出高性能的加气混凝土，具有良好的经济效益、环境效益和社会效益。
