Abstract
Abstract Electrochemical chloride extraction (ECE) is an effective method to remove chloride ions in reinforced concrete. In addition, cracks in concrete have self‐healing properties. The self‐healing properties of concrete may affect the ECE process. Based on moving mesh technology, this paper simulates the ion migration process of ECE in crack‐self‐healing concrete. According to the simulation results, the distribution of ions in the reinforced concrete and the electric potential change law inside the concrete are analyzed during the ECE process. The effects of cracks or no cracks in the anode area of ECE, self‐healing or no self‐healing, and different self‐healing rates on the efficiency of ECE were discussed. This research will have a positive impact on ECE's research.
