Abstract

This study focuses on evaluating the electrochemical behavior of steel reinforcement in reinforced concrete structures, particularly those located in marine environments where chloride-induced corrosion is a common problem. The use of patch repair is a popular method for repairing corroded reinforced concrete structures, but improper evaluation of the corrosion cause and extent can lead to rapid deterioration and degradation of the structure. Therefore, it is crucial to monitor the performance of the repaired structure using appropriate methods. The study measures two corrosion parameters, the corrosion potential and the electrical resistivity, to evaluate the effectiveness of the patch repair method. The results show that the patch repair method can significantly affect the performance of the reinforced concrete structure, and the evaluation of the corrosion potential and resistivity distribution is essential to assess the effectiveness of the repair method.
