摘要
随着混凝土技术的发展,混凝土耐久性变得越来越重要,高性能混凝土广泛应用。本文研究了超细粉煤灰(UFA)、一级粉煤灰(FAⅠ)、磨细粒化高炉矿渣(GBFS)的减水效应。试验以普通硅酸盐水泥为原料,UFA、FAⅠ和GBFS为矿物掺合料,采用单独使用和复合使用的方法成功配制C50高性能混凝土,并比较研究了不同胶凝粉体高性能混凝土的力学性能、体积稳定性和耐久性能。
With the development of concrete technology, the durability of the concrete is becoming more and more important. The high-performance concrete (HPC) is widely used. This paper studied the water reducing effect of Ultra-fine fly ash (UFA), the frost class fly ash (FA I ) and ground blast furnace slag (GBFS). The experiment succeeded in compounding C50 high-performance concrete by using normal Portland cement .as basic material and UFA. FA I and GBFS as mineral admixtures. The mechanical property, volume stability and durability of HPC which is composed of different cementitious powder system were also studied.
