Abstract: In this study, the method, which estimated the change of the corrosion rate of existing reinforced concrete under unsteadily changing temperature, was proposed. In chapter two, the change of the corrosion rate was experimentally investigated using a mortar specimen exposed under the environment, where temperature changed. Next in chapter three, the method for estimating the internal temperature of the mortar specimen and the corrosion rate of the steel bar from changing temperature was constructed. Furthermore in chapter four, cases, which utilized this estimation method for the corrosion survey of existing structures, was imagined. As results, 1) the method, which estimated the corrosion rate under changing temperature, was able to be constructed. 2) It was clarified that the quantity of the rust in any period could be estimated by using this method, if the corrosion rate of the existing reinforced concrete was investigated only at once.
