摘要 通过试验,研究了湿度变化对于氯离子迁移的影响,此外,还通过渗透试验研究了不同氯离子浓度下的湿度迁移规律。结果表明,湿度梯度的存在加速了氯离子在混凝土中的迁移,而氯离子的作用则又加速了湿度的迁移。最后,对试验结果进行了补充的理论分析,表明氯离子和湿度之间存在一耦合效应,二者之间的相互作用将加速氯离子在混凝土中的迁移。 The interaction between moisture diffusion and chloride penetration was investigated through migration experiment and seepage test.The test results show that moisture diffusion accelerates the chloride diffusion and the inverse effect of chloride penetration on moisture is also acclerated. And this result is verified by the theory of Fick's second law. The experiment results and the theorical analysis on chloride and moisture diffusion are comfirmed to be match each other.
