Abstract
본 연구에서는 표면마감재를 시공한 철근 콘크리트 구조물을 대상으로 표면마감재의 염소이온 침투 저항성을 급속 염화물 침투실험으로 평가하였다. 또한 실험에서 얻어진 콘크리트와 마감재료의 염소이온 확산계수를 이용하여 FEM 해석에 의한 염해 내구수명을 해성함으로써 표면 마감재가 시공된 철근 콘크리트 구조물의 내구성 향상에 관한 기초 자료를 제공하고자 한다
Chlorie ion diffusion is the most important thing of occuring deterioration in RC structure. So it is important to decide the precise chloride ion diffusion coefficient in order to predict the durability life in RC structure. The purpose of this study is to analyze the established data, which are restricted by chloride diffusion coefficient, and to calculate chloride ion diffusion coefficient using RCPT test. To examine the prediction of the concrete structure durability by an FEM analysis and the chloride diffusion coefficient as a variable. Each surface finishing materials were effective on the increment of chloride penetration resistance, but showed a little different effect depending on the type of surface finishing material.
