摘　　要：论述了大掺量磨细矿渣粉对混凝土性能的影响，研究结果表明：用S95磨细矿渣粉和少量粉煤灰可以配制出早期抗裂性和耐久性均好的C50-C70高性能混凝土，84d氯离子扩散系数均小于1．50×10^12m^2／s,大掺量磨细矿渣粉高性能混凝土的收缩徐变较普通混凝土小。The influences of adding considerable amount of ground slag powder to concrete on the performance of the concrete itself are described. The results of test study of the concrete indicate that the utilization of considerable amount of S95 ground slag powder together with a little flyash can produce C50-C70 high performance concrete with both good early anti-cracking and durability properties. The chlorine ion diffusion coefficient of the concrete at age of 84 d is less than 1.50×10^12m^2/s, and the shrinkage and creep of the concrete are less than those of normal concrete.
