The purpose of this paper is to verify the applicability of a simple water supply method using water supply curing system as an external solution supply method in electrochemical corrosion control method. The study was conducted focusing on (a) the design method, (b) the repair effect of the amount of solution, the distance between the concrete surface and the anode, and the type of anode material, and (c) the applicability to the actual structure.
As a result, a design method for selecting the suction port position and suction machine based on computation fluid dynamics was established. In addition, there was no effect of the amount of solution on the realkalization and desalination effects. On the other hand, the electrodeposition effect was found to differ depending on the type of anode material. It was also found that the greater the distance between the concrete surface and the anode, the greater the effect. Furthermore, as a result of application to actual structures, it was confirmed that the simple water supply method was easy to construct and could be applied to complex surface shapes, and also contributed to the suppression of external solution disappearance.
