摘　　要：研究了单掺粉煤灰、磨细钢渣和双掺粉煤灰-磨细钢渣对混凝土强度和氯离子扩散系数的影响。试验表明:双掺粉煤灰-磨细钢渣的混凝土强度和抗氯离子渗透性能优于基准组及单掺粉煤灰、磨细钢渣的混凝土,同时磨细钢渣对混凝土性能改善的贡献稍大于粉煤灰。The effects of the individual mixture of fly ash or steel slag and the combinations of fly ash and steel slag on strength and chloride diffusion coefficient of concrete are studied.The results indicate that comparing to the pure cement sample and the individual mixture of fly ash or steel slag cement sample,the combination of the admixtures can improve the mechanical properties and the resis-tance to chloride ion permeability of concrete.The contribution of steel slag to concrete performances is slightly larger than fly ash.
