Long-term effect of chloride ion penetration on concrete durability in the Persian Gulf coast
Due to the widespread use of concrete structures in different climatic conditions, the issue of damage to these types of structures and as a result of their repair and maintenance, is one of the main topics discussed by concrete experts. One of the causes of corrosion of steel in reinforced concrete in corrosive environments, especially on the shores of the Persian Gulf, is chloride ion. There are many factors affecting the penetration of chlorine ions in concrete, all of which can be summarized in the quality of concrete. One of the main materials used in reinforced concrete structures in corrosive conditions is surface coating. In this study, the performance of five different types of processing in the marine environment (Persian Gulf) was investigated. Have: 27-day treatment with water, 6-day treatment with water, 3-day treatment with water, 1-day treatment with water, treatment with curing agent and without curing. Based on the results, the best performance in terms of resistance to chloride ion penetration varies depending on the exposure conditions. Observations show that curing with curing agent has a good performance in terms of resistance
