Non-autoclaved silicon-manganese slag aerated concrete thermal insulation building block and preparation method thereof
The invention discloses a non-autoclaved silicon-manganese slag aerated concrete thermal insulation building block and a preparation method thereof, and belongs to the technical field of building materials. The non-autoclaved silicon-manganese slag aerated concrete thermal insulation building block comprises the following raw materials by weight: 75-85 parts of silicon-manganese slag, 40-50 parts of silica fume, 30-40 parts of lime, 55-70 parts of cement, 5-10 parts of gypsum, 0.2-0.3 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 110-130 parts of water. The preparation method comprises the following steps: putting ball-milled binding materials such as the silicon-manganese slag, the cement and the gypsum into a stirrer for dry stirring; fully mixing the above, adding water, stirring to prepare slurry, adding aluminum powder into the slurry, and fully and quickly stirring; pouring the slurry into a mold, and standing for pre-curing; and then cutting a green body, and then maintaining the green body. According to the process, the silicon-manganese slag is applied to preparation of the aerated concrete instead of fly ash, so that the problem of low content of active SiO2 in the silicon-manganese slag is solved, the problem of fly ash shortage successively appearing in some areas is also solved, and pollution caused by accumulationof the silicon-manganese slag is reduced.
本发明公开了一种免蒸压硅锰渣加气混凝土保温砌块及其制备方法，属于建筑材料技术领域，其原料按重量份包括以下组分：硅锰渣75~85份、硅灰40~50份、石灰30~40份、水泥55~70份、石膏5~10份、铝粉0.2~0.3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110~130份，其制备方法为：将球磨好的硅锰渣、水泥、石膏等胶凝材料放入搅拌机中进行干搅拌；充分混合后加水搅拌制成料浆，在料浆中加入铝粉充分快速搅拌；然后将料浆浇筑到模具中静停预养；之后将坯体进行切割，而后进行养护。本工艺将硅锰渣代替粉煤灰应用于加气混凝土的制备中，解决硅锰渣中活性SiO2含量低的问题，既解决了某些地区陆续出现的粉煤灰短缺问题，又减少了硅锰渣的堆积污染。
