Microorganism mineralized high-strength carbonized aerated concrete and preparation method thereof
The invention provides microorganism mineralized high-strength carbonized aerated concrete and a preparation method thereof. The microorganism mineralized high-strength carbonized aerated concrete is prepared from the following components in parts by weight: 100 parts of carbonized cementing material, 10-25 parts of water, 3-6 parts of aerobic microorganism powder with mineralization and deposition functions, 3-7 parts of hydrogen peroxide, 0.2-0.3 part of water reducing agent and 1-10 parts of nutrient solution, concrete slurry prepared from the components is subjected to pouring molding, standing curing and CO2 carbonization curing, and the microorganism mineralized high-strength carbonized aerated concrete is obtained. According to the method, microorganism mineralization pre-carbonization and kiln tail flue gas carbonization are combined, the problems that the carbonization curing condition of the aerated concrete is high, and the interior of the aerated concrete is difficult to completely carbonize are solved, the method is economical and environmentally friendly, and the prepared aerated concrete is uniform in carbonization and good in heat preservation performance and shrinkage performance.
本发明提供了一种微生物矿化高强碳化加气混凝土及其制备方法，微生物矿化高强碳化加气混凝土包括如下重量份的各组分：碳化胶凝材料100份，水10～25份，具有矿化沉积功能的好氧微生物菌粉3～6份，过氧化氢3～7份，减水剂0.2～0.3份，营养液1～10份；上述组分制备成的混凝土浆体经浇筑成型、静停养护后进行CO2碳化养护得到所述微生物矿化高强碳化加气混凝土。本发明将微生物矿化预碳化和窑尾烟气碳化结合，解决了加气混凝土碳化养护条件高，内部难以完全碳化的问题，且经济环保，制备得到的加气混凝土碳化均匀，保温性能和收缩性能良好。
