| 摘 要： | 对掺粉煤灰复合超细粉砂浆和高性能混凝土的性能进行了研究，结果表明，以３０％～７０％（质量分数）的粉煤灰复合超细粉等量取代水泥，可使水泥浆体的凝结时间延长，并能配制出Ｃ７０～Ｃ８０的高性能混凝土，且混凝土拌合物具有较小的坍落度损失。

| Abstract: | The fluidity and compressive strength of HPC with pulverized fly ash composite(PFAC) arepresented. The experimental results indicate that PFAC can improve the fluidity and compressivestrength of concrete at 30%～70% (by mass) replacement of cement. A high performance concretewith PFAC had been prepared with a large slump, high long-term compressive strength, low slumploss, and low drying shrinkage ratio. The replacement of cement by PFAC in the range of 30%～70%can not only improve the properties of concrete, but also have positive the environmental effect. |
