Inorganic cementing material, foam concrete and preparation method thereof
The invention discloses an inorganic cementing material which comprises the following components in percentage by mass: 40%-50% of calcined coal gangue, 40%-45% of Portland cement clinker, 5%-10% of gypsum and 1%-5% of aluminum sulfate salt. The coal gangue powder contained in the cementing material can reach 50% at most, and meanwhile it can be guaranteed that the 3d strength is not lower than 25 MPa. According to the cementing material, the use amount of the coal gangue powder can be greatly increased, the coal gangue powder can be effectively consumed, meanwhile, the prepared cementing material is higher in early strength, and the requirement for rapid hardening and early strength of foam concrete can be met.
本发明公开了一种无机胶凝材料，按照质量百分比计算，所述无机胶凝材料包括如下组分：煅烧煤矸石为40%~50%，硅酸盐水泥熟料为40%~45%，石膏为5%~10%，硫酸铝盐为1%~5%。本发明所述胶凝材料中，所含煤矸石粉最高可以达到50%，同时可保证3d强度不低于25MPa。本发明所述胶凝材料可大幅增加煤矸石粉的使用量，可有效消纳煤矸石粉，同时使的所制备胶凝材料早期强度更高，可满足泡沫混凝土快硬早强的要求。
