海工混凝土抗氯离子渗透性试验方法的研究

摘要

Feasibility and necessity of using resistance to chlorine ions＇ penetration as a overall indicator that evaluates durability of marine concrete are analysed,on the base of research status of marine concrete at home and abroad.Accelerating tests are applied to study chlorine ion diffusion coefficient and predictive models of marine concrete＇durability in recent years.And in this paper,merit and demerit of those test methods are discussed which is important in enhancing service life of marine concrete.%结合国内外海工混凝土耐久性研究现状,分析了将抗氯离子渗透性作为评价海工混凝土耐久性的综合指标的可行性和必要性;针对近年来用加速试验来研究海工混凝土氯离子扩散系数和混凝土耐久性预测模型,探讨了各种试验方法的优点和缺点,对于提高海工混凝土服役寿命有着重要的意义。
