对混凝土氯离子渗透性试验评价方法的商榷

Discussion of chloride ion permeability test assessment methods in concrete

概述了目前混凝土氯离子渗透性测试方法当中混凝土氯离子浓度表示和评价方法的不足。指出混凝土毛细孔结构对氯离子渗透和钢筋局部腐蚀(坑蚀)的影响。并对混凝土氯离子渗透性试验的氯离子浓度表示和评价方法提出建议。

The defects of chlorinity expressing method and chlorinity assessment method, which exists in the current test methods of chloride ion permeability in concrete,are summarized. Also,the influences of the capillary structure to chloride ion permeability and reinforcement localized corrosion （namely pitting corrosion） are pointed out. Some advice regarding chlorinity expressing measure and assessment method in the chloride ion permeability test is proposed.
