염화물 및 방청제 첨가 콘크리트 내부 철근의 부식거동평가에 관한 실험적 연구

Abstract

In this study, Corrosion behavior in mortar was observed by the passage of time by using EIS method. As a result of EIS experiment, equivalent circuit and changes of Impedance parameter could be observed. In addition, it was confirmed that impedance of rebar in concrete and corrosion rate according to the amount of NaCl and LiNO2 were different.
