Method for preparing autoclaved aerated concrete from unburned coal gangue
The invention relates to the technical field of decarbonization modification activation treatment of unburned coal gangue and preparation of autoclaved aerated concrete. The unburned coal gangue decarburization modifier is any one of nitrate, potassium permanganate, H2O2 and the like. The invention relates to an unburned coal gangue decarburization modification activation method, which comprises composite decarburization modification activation such as physical decarburization, mechanical activation, chemical decarburization modification activation and the like. The autoclaved aerated concrete prepared from the unburned coal gangue comprises more than 50% of the decarburized modified activated gangue material. According to the invention, the tolerance of the product to the carbon content of the coal gangue is improved, the activity of the coal gangue raw material is excited, the hydrothermal reaction is promoted to be fully carried out, and a multi-mineral gelling substance composed of several kinds of hydrated calcium silicate and other hydrated minerals can be generated, so that a more compact microcrystalline structure is obtained; and the formation of a micropore structure in a pore wall is facilitated, so that the product has good physical properties.
本发明涉及未燃煤矸石脱碳改性活化处理及制备蒸压加气混凝土技术领域。所述未燃煤矸石脱碳改性剂为硝酸盐、高锰酸钾、H2O2等的任意一种。一种未燃煤矸石脱碳改性活化方法，包括：物理脱碳、机械活化、化学脱碳改性活化等复合脱碳改性活化。一种未燃煤矸石制备的蒸压加气混凝土，其物料包含50％以上的上述脱碳改性活化矸石料。本发明提高了制品对于煤矸石碳含量的容忍度，激发了煤矸石原料的活性，有利于促进水热反应充分进行，能够产生几种水化硅酸钙和其他水化矿物共同组成的多矿物胶凝物质，从而获得更加致密的微晶结构，还有利于孔壁中微孔结构的形成，从而使制品获得良好的物理性能。
