고로슬래그 치환율에 따른 콘크리트의 염화물 침투특성 및 부식속도에 관한 실험적 연구

Abstract

Corrosion of reinforcing bars embedded in concrete by chloride penetration is an important factor in determining the durability life of reinforced concrete structures. In this study, chloride ion penetration resistance of concrete and the amount of total chloride ion in concrete were evaluated according to cement replacement ratio of blast furnace slag. And corrosion rate of reinforced concrete embedded in concrete due to chloride penetration was evaluated. In this study, the relationship between the chloride penetration characteristics of concrete and the corrosion rate of rebar embedded in concrete according to blast slag replacement ratio is analyzed.
