Non-autoclaved fly ash aerated concrete thermal insulation building block and preparation method thereof
The present invention discloses a non-autoclaved fly ash aerated concrete thermal insulation building block and a preparation method thereof, and relates to the technical field of building materials. The non-autoclaved fly ash aerated concrete thermal insulation building block comprises 250-350 parts of fly ash, 55-95 parts of lime, 10-20 parts of gypsum, 80-140 parts of cement, 0.3-0.7 part of aluminum powder, 1-2 parts of sodium sulfate, 0.05-0.15 part of triethanolamine, 3-4 parts of lauryl sodium sulfate, and 260-290 parts of water. The preparation method comprises the following steps: mixing and stirring the fly ash, quick lime, desulfurized gypsum, cement and other cementing materials, adding water, mixing with dry materials, and stirring to prepare slurry; and adding the aluminum powder and other additives into the slurry, fully stirring again, then pouring into a mold box, and moving the mold box into a static curing chamber for static gas generation. According to the method, large-volume fly ash is used, and industrial solid waste fly ash is comprehensively utilized, so accumulation waste is reduced, the problem of solid waste treatment of a thermal power plant is solved, use of other building materials is reduced, and the national building energy-saving development target is met.
本发明公开了一种免蒸压粉煤灰加气混凝土保温砌块及其制备方法，涉及建筑材料技术领域，包括粉煤灰250~350份、石灰55~95份、石膏10~20份、水泥80~140份、铝粉0.3~0.7份、硫酸钠1~2份、三乙醇胺0.05~0.15份、十二烷基硫酸钠3~4份、水260~290份。其中制备方法为：先将粉煤灰、生石灰、脱硫石膏以及水泥等胶凝材料混合进行搅拌，再加水与干料混合搅拌制浆；在浆料中加入铝粉及其他外加剂再次进行充分搅拌，然后浇筑到模具箱内，将模具箱移动到静养室内静止发气；此工艺使用大掺量粉煤灰，将工业固体废弃物粉煤灰综合利用，减少堆积浪费，解决了热电厂固废处理问题，并减少了其他建筑材料的使用，符合国家建筑节能发展目标。
