This paper reports the results of accelerated test and outdoor exposure test on the repair performance on corrosion of reinforcing bar in salt containing concrete by various repairing materials. The results are following ; ・ The surface covering material has the protection effect of a reinforcing bar corrosion, with the part that is not repairing.・ The repair performance reduces it, if it does not do chipping the concrete of the periphery of reinforcing bar corrosion. ・ The primer has a repair performance in a section recovery area. ・ The repair performance differs by the type of a repair material, and the repair performance of polymer cement differs by the physical properties and the addition of inhibitor. ・ The primer and section recovery material recommend that uses the repair material of the same type. ・ The accelerated test is able to estimate the result in 1/12.4 periods of the outdoor exposure test.
