抗水渗透法、RCM法和电通量法是从不同角度反映混凝土密实性的测试方法，研究这些测试指标的相关性对于科学、合理选择设计参数具有重要意义。研究分别采用抗水渗透法、RCM法和电通量法测试C20～C60强度等级混凝土的渗透性，并考虑了不同含气量和不同粉煤灰掺量的影响，分析了3种渗透性测试方法之间的相关性。结果表明：对于大掺量粉煤灰混凝土，RCM法和渗水高度法的相关性较差，RCM法与电通量法则具有较好的线性相关性。

Water penetration method, RCM method and electric flux method could reflect the concrete density from various angles. The research on the correlations of these testing parameters is of great importance to parameter selection. The study tested the permeability of concrete strength C20 to C60 by water penetration method, RCM method and electric flux method, respectively, and considering the influence of the air content and fly ash content. The correlations between above 3 test methods were discussed. The results show that the correlation between RCM method and water penetration method for high volume fly ash concrete is bad, and there is a good correlation between RCM method and electric flux method.
