一种蒸压加气混凝土及其制备方法
摘要：
本发明公开了一种蒸压加气混凝土及其制备方法，本发明的混凝土由矿物原料、碱性激发剂、发泡剂、稳泡剂、缓释剂等组成。矿物原料中粉煤灰占80~100wt.%，其他矿物原料含有矿渣、偏高岭土、硅灰、钢渣、循环硫化床底灰等；碱性激发剂是矿物原料质量的40~55wt.%；发泡剂是矿物原料质量的0.13~5wt.%，稳泡剂是矿物原料质量的0.03~0.09wt.%，缓释剂是矿物原料质量的2~3.5wt.%。碱性激发剂包括水玻璃和NaOH/KOH，与矿物原料、发泡剂和稳泡剂混合搅拌，可装入模具预制成型，也可浇注成型，在60-160oC，0.1~1MPa下加压蒸养1~24h。
摘要（英）：

The invention discloses an autoclaved aerated concrete and a preparation method thereof, and the autoclaved aerated concrete comprises mineral raw materials, an alkaline exciting agent, a foaming agent, a foam-stabilizing agent, a slow-release agent and the like. The mineral raw materials comprise 80-100wt.% of fly ash, and other mineral raw materials comprise mineral waste residue, metakaolin, silica fume, steel slag, circulating fluidized bed bottom ash and the like; the alkaline exciting agent mass is 40-55wt.% of the mineral raw material mass, the foaming agent mass is 0.13-5wt.% of the mineral raw material mass, the foam-stabilizing agent mass is 0.03-0.09wt.% the mineral raw material mass, and the slow-release agent mass is 2-3.5wt.% of the mineral raw material mass. The alkaline exciting agent including sodium silicate and NaOH / KOH, the mineral raw materials, the foaming agent and the foam-stabilizing agent are mixed for stirring, then are filled in a mould for prefabrication forming or casting forming, and maintained by autoclaving for 1-24h at 60-160 DEG C under 0.1-1MPa.
