摘　　要：文章采用ASTM C1202和RCM法研究了养护龄期为7 d、28 d、56 d的掺加了粉煤灰、矿粉的混凝土的渗透性能。实验结果表明:养护龄期为7 d和28 d时,掺加粉煤灰的混凝土的电通量和氯离子扩散系数均大于普通水泥混凝土,养护龄期为56 d时,掺加粉煤灰的混凝土的电通量和氯离子扩散系数均小于普通水泥混凝土;混凝土的电通量和氯离子扩散系数具有较好的相关性。The permeability of concrete mixed with fly ash ,slag cured for 7d ,28d ,56d are studied by the test as designated in ASTM C1202 and RCM test.It is showed that when cured for 7d and 28d,the flux of the concrete mixed with fly ash is bigger than that without fly ash,when cured for 56d,the flux of the concrete mixed with fly ash is smaller than that without fly ash;flux and chloride diffusion coefficient have good correlation.
