混凝土抗氯离子渗透性试验方法综述

Overview of test methods of chloride ion penetration in concrete

混凝土抗氯离子渗透性是混凝土重要的耐久性劣化指标之一,客观准确而实用的试验方法显得尤为重要。对国内外混凝土抗氯离子渗透性的试验方法以及相关标准或规范进行了充分的调研,比较了各种主流试验方法或测试技术的原理和适用范围,并分析了各自的优缺点,突出阐述了试验室和现场均适用的测试方法,为GBJ82—85《普通混凝土长期性能和耐久性试验方法标准》的修订提供参考。

The resistance of concrete to chloride ion penetration is one of durability indicators;therefore, objective, accurate and practical test methods are of vital importance.The test methods and techniques of concrete resistance to chloride ingression around the world are reviewed;their principle, application scope, merits and shortcomings are compared, and prominence has been given to the test methods that can be used both in laboratory and on site.All these can give sufficient references to the revision of Standard for Test Methods of Long-Term Properties and Durability on Ordinary Concrete （GBJ 82-85 ）.
