Repair effect of cracked reinforced concrete based on electrochemical rehabilitation technology

To solve the problem of durability deterioration of cracked concrete structures in coastal environments, this study investigates the effect of repairing loading cracks and corrosive cracks. In particular, the immediate and long-term effects of combining electrochemical repair technology with traditional repair methods were studied. After the repair, the corrosion potential of steel bars, cracking duration, and cracking speed obtained by different repair methods were compared. The results showed that the repair effect of the comprehensive repair technique is significantly better than using a single repair method. Based on the characteristics of the cracks, the sequence of each step in the combined repair technique was designed.
