| Abstract: | 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. |

| Keywords: | chloride ion permeability capillary structure average concentration local concentration reinforcement corrosion pitting corrosion |
