摘　　要：采用ASTMC1202及氯离子扩散系数快速测定法(RCM法)研究了不同因素对混凝土电通量和氯离子扩散系数的影响规律,探讨了二者之间的相关性。结果表明,当水灰比、单位立方米水泥用量以及矿渣粉掺量变化时,混凝土的电通量和氯离子扩散系数之间具有较好的相关性;当含气量和粉煤灰掺量变化时,二者之间的相关性较差。The effects about different factors to the rapid chloride permeability test results and chloride diffusion coefficient of concrete are studied by the test as designated in ASTM C 1202 and RCM test, and the correlation of the rapid chloride permeability test results and chloride diffusion coefficient is also discussed.It is showed that the rapid chloride permeability test results and chloride diffusion coefficient have good correlation when water-cement ratio, cement content, and slag content are altered respectively, but the correlation is not good when air content and fly ash content are altered.
