通过引入微研磨介质以及表面改性剂对普通硅酸盐水泥进行研磨,制备颗粒更小、粒度分布更合理、胶凝效率更高的高效胶凝水泥。同时对高效胶凝水泥进行比表面积、标准稠度用水量、激光粒度分析、水化热以及混凝土试验分析,研究表明:微研磨介质与表面改性剂能大幅提高水泥研磨效率,提高水泥细度,降低能耗,制备出的高效胶凝水泥以适量掺量加入到混凝土中,能优化水泥颗粒级配,提高水泥利用率,进而提高混凝土强度,同时能减少水泥用量。
Through the introduction of micro-grinding media and surface modifier of ordinary Portland cement grinding, preparation of smaller particles, the particle size distribution is more reasonable, more efficient gelling high efficiency cementitious cement. At the same time, the specific surface area, water content of standard consistency, laser particle size analysis, hydration heat and concrete test were also analyzed. The results show that the micro-grinding media and surface modifier can greatly improve the grinding efficiency of cement and improve the fineness of cement, Reduce energy consumption, the preparation of high-efficiency cementitious cement added to the amount of concrete admixture, can optimize the grading of cement particles, improve cement utilization, thereby increasing the strength of concrete, while reducing the amount of cement.
