摘要
通过试验研究，比较了不同品种、等级的粉煤灰对高性能混凝土的工作性、水泥与外加剂的相容性、强度及抗渗性等性能的影响，分析了粉煤灰在高性能混凝土中的作用机理，综合评价了粉煤灰在高性能混凝土中的利用价值。
The influence of fly ash of different varieties and grades on HPC is discussed in this paper based on our experiments in the aspects of workability, strength, permeability and compatibility between cement and adnixture. Some ideas about the mechanism of the actions of fly ash on HPC are also proposed according to our analysis. The utilization significance of fly ash is compositively evaluated in the end.
