철근 콘크리트의 혼화재와 물시멘트비에 따른 철근의 임피던스에 관한 실험적 연구

Abstract

In this study, the impedance of reinforced concrete embedded in concrete was measured and compared with W/B and admixture replacement ratio. As a result, the impedance of rebars increased in all frequency sections with increasing blast furnace slag replacement amount of cement in all W/B Respectively. It is considered that the electro resistance in the concrete increases due to the potential hydraulic properties of the blast furnace slag, and thus the polarization resistance also increases.
