混凝土抗氯离子渗透性试验方法

Investigation of test methods of chloride ion penetration in concrete

为配合《普通混凝土长期性能和耐久性能试验方法标准》(GBJ82-85)的修订,促进对混凝土抗氯离子渗透性试验方法的了解与交流,对国内外混凝土抗氯离子渗透性试验方法及标准进行了充分的调研.详细调查了国内外混凝土抗氯离子渗透性试验方法和测试技术的标准规范,比较了各种试验方法或测试技术的原理和适用范围,并分析了各种试验方法的优缺点.混凝土的抗氯离子渗透性是其耐久性的重要指标之一,建议在《普通混凝土长期性能和耐久性能试验方法标准》中补充混凝土抗氯离子渗透性试验方法.

To cooperate with the revision of Standard for Test Method of Long-Term Properties and Durability on Ordinary Concrete (GBJ82-85), an elaborate investigation has been executed on the test methods and standards of chloride ion penetration in concrete. The test methods and techniques of concrete's resistance to chlorides ingression around the world are reviewed, and their principle, application scope, merits and shortcomings are compared. It is further proved that the resistance of concrete to chloride ion permeation is one of the most important durability indices, therefore, it is reasonable to be added into the standard (GBJ82-85) in China.
