Gypsum-based calcination-free sulphoaluminate cement and preparation method thereof
The invention belongs to the technical field of special cement, and relates to gypsum-based calcination-free sulphoaluminate cement and a preparation method thereof. The invention aims to solve the problems of high energy consumption and high pollution in production of sulphoaluminate cement calcined clinker and the problems of regeneration and high-quality utilization of multiple solid wastes. The gypsum-based calcination-free sulphoaluminate cement is prepared from building gypsum, anhydrite, silica fume, superfine fly ash, cement, carbide slag, zeolite powder, expanded perlite loaded microbial powder, aluminum sulfate, melamine, borax, sodium citrate and a polycarboxylic acid high-performance water reducing agent. The baking-free sulphoaluminate cement has the advantages that the baking-free sulphoaluminate cement is prepared from multiple solid waste powder, effective nutrient components are provided for microorganisms, breeding of the microorganisms and increase of excreta are promoted, the self-repairing property and comprehensive performance of the baking-free sulphoaluminate cement are further improved, and the multi-component solid waste powder is optimally combined, and the enhanced excitation component and the microorganisms are introduced, so that the baking-free sulphoaluminate cement is prepared. And normal hydration and strength increase of the baking-free sulphoaluminate cement are realized.
本发明属于特种水泥技术领域，涉及一种石膏基免煅烧类硫铝酸盐水泥及其制备方法。为解决生产硫铝酸盐水泥煅烧熟料的高能耗、高污染问题，以及多固废的再生高质利用问题，本发明石膏基免煅烧类硫铝酸盐水泥包括建筑石膏、硬石膏、硅灰、超细粉煤灰、水泥、电石渣、沸石粉、膨胀珍珠岩附载微生物粉、硫酸铝、三聚氰胺、硼砂、柠檬酸钠、聚羧酸高性能减水剂，通过三聚氰胺、硼砂、柠檬酸钠的合理匹配，为微生物提供了有效营养组分，促进了微生物的繁育和排泄物的增多，进而提高了免烧类硫铝酸盐水泥的自修复性和综合性能，通过多组分固废粉体优化组合，在引入增强激发组分和微生物，实现了免烧类硫铝酸盐水泥的正常水化和强度增长。
