摘　　要：本文通过粉煤灰、矿粉、硅粉三者复掺来研究其对水泥性能的影响,力求发挥粉煤灰、矿粉、硅粉三者的各自优势,实现优势互补,配制出工作性能良好、力学性能较强的高性能掺合料。实验结果表明粉煤灰、矿粉、硅粉的复掺比例为5%∶13%∶7%,对此比例掺合料的强度测定及水化样分析,其性能对比纯水泥有显著地提高。The paper study affect of fly ash, slag powder, silica fume of cement properties. It is to play their respective advantages and complement each otherg advantages about three factors. Finally,the high- performance of admixture that have a good working performance and mechanical properties be formulated. The results indicated that the ratio among fly ash, slag powder, silica fume is 5% ： 13% ： 7%. The admixture performance to the intensity determination and hydration analysis is improved obviously than the pure cement.
