Abstract
철근 콘크리트 구조물 내 철근에 부식이 발생하면 국부적으로 pH가 떨어지며 이때 고정화 염소이온은 자유 염소이온이 되어 철근 부식 위험성이 급격히 증가하게 된다. 시멘트의 산 저항성 능력은 시멘트의 화학 조성에 따라 달라지는 것으로 알려져 있지만 그에 대한 심도있고 세분화된 연구는 미비한 실정이다. 따라서 본 연구에서는 시멘트 내 클링커 중 C3A 함량에 따른 산 저항성을 평가하였다.
When the corrosion of steel in concrete is initiated, a local pH fall cause a release of bound chloride into pore solution, which can particepate in the corro sion process. Though the acid neutralisation capacity was regarded as a property of cement, i t has not been fully defined. In this reason, the present study was di scussed about the acid neutralisation capacity according to the C 3 A content in cement.
