Abstract
In this paper, the electrodeposition method for the rehabilitation of cracked reinforced concrete, based on the electrochemical technique, is presented. The main purpose of this paper is to apply this technique to reinforced concrete members on land. After cracking with a specified load (crack width 0.5mm), 10×10×20cm concrete specimens with embedded steel bars were immersed in several solutions, then a constant current density between the embedded steel in concrete and an electrode in the solution was applied for 4-20 weeks. The results indicate that electrodeposits formed in this process are able to close concrete cracks and to coat the concrete surface and that formation of these electrodeposits is confirmed to have an effect of protection against detrimental materials. Therefore, it is demonstrated that the electrodeposition method can be usefully applied for the rehabilitation technique of concrete.
