GB/T 31933-2015 in English

《GB/T 31933-2015模拟海洋环境钢筋耐蚀试验方法》由TC183（全国钢标准化技术委员会）归口，TC183SC11（全国钢标准化技术委员会金属和合金的腐蚀分会）执行，主管部门为中国钢铁工业协会。
本标准规定了模拟海洋环境下混凝土结构中钢筋耐氯离子腐蚀性能的评价方法。
本标准适用于混凝土中的钢筋耐氯离子腐蚀性能的测试。
本标准包括以下两种方法,试验人员可按照实际条件进行选择。
方法 A―――钢筋在混凝土中耐氯离子腐蚀性能测试方法。通过达到规定电量的时间来评价钢筋腐蚀性能。
方法 B―――海洋环境下钢筋在混凝土结构中锈蚀速率的对比试验方法。通过与对比钢筋进行锈蚀速率对比来评价钢筋腐蚀性能。

Scope

This standard specifies the evaluation method for the corrosion resistance of steel bars in concrete structures under simulated marine environment. This standard applies to the test of the corrosion resistance of steel bars in concrete. This standard includes the following two methods, and the test personnel can choose according to the actual conditions. Method A - test method for resistance to chloride ion corrosion of steel bars in concrete. The corrosion performance of steel bars is evaluated by the time to reach the specified electric charge. Method B—Comparative test method for the corrosion rate of steel bars in concrete structures in a marine environment. The corrosion performance of steel bars was evaluated by comparing the corrosion rate with the comparison steel bars.
