摘 要：为配合中国建筑学会《混凝土抗氯离子渗透性的交流电测量方法》评价标准的建立，采用了交流电测法、电通量法（ASTMC1202）和快速氯离子扩散系数法（RCM）三种试验方法，定量评价了普通、高强和高性能混凝土抗Cl-渗透的能力。结果表明，当水灰比、粉煤灰及矿渣粉掺量变化时，交流电测法在多数情况下具有较好的适应性；交流电测法与ASTMC1202法、RCM法具有良好的相关性，相关系数分别为0.94086、0.77089。 Abstract:InordertocooperatewiththeestablishmentoftheevaluationstandardofActivitiesforthemeasurementofchlorideionpermeabilityofconcretebyArchitecturalChineseSocietyofChina,alternatingcurrentmethod,electricfluxmethod(ASTMC1202)andrapidchlorideiondiffusioncoefficientmethod(RCM)wereusedtoquantitativelyevaluatetheresistanceofordinary,high-strengthandhigh-performanceconcretetochlorideionpenetration.Theresultsshowthatwhenthewater-cementratio,thecontentofflyashandslagpowderchange,thealternatingcurrentmethodhasbetteradaptabilityinmostcases.ThealternatingcurrentmethodhasgoodcorrelationwithASTMC1202methodandRCMmethod,andthecorrelationcoefficientis0.94086and0.77089respectively.
