In this study, in order to improve the accuracy of estimate method of chloride content in concrete structures using electromagnetic wave, simulation of attenuation electromagnetic waves (SAE) was constructed considering influence of temperature, relative humidity and the chloride ion content were experimented in laboratory. As a result, the precision can presume average chloride content in the every depth of concrete from the conductivity calculated by SAE. Furthermore the chloride ion permeation degree by the long-term deterioration is presumed and the way to predict the time when corrosion of re-bar starts is proposed.
