This paper deals with the rust-inhibiting properties of patching materials containing chloride ion fixing admixture and nitrous acid type admixtures by the outdoor exposure of specimens modeling RC structure. As a result, the self potential of rebar differs from base and patch sides for the chloride ion fixing admixture. Such differences are considerably recognized for the nitrous acid type admixtures. Regardless of the self potential of the rebar, the corrosion of rebar is not recognized at the patch side. The macro-sell corrosion of the rebar is occurred in the base side, and increased with increase in the chloride ion content.
