Evaluation of Chloride Ion Penetration Characteristics for Concrete Structures at Coastal Area
, 2011 항만콘크리트 구조물의 내구성 저하의 중요한 요인은 염소이온침투에 의한 철근의 부식이다. 따라서, 항만콘크리트 구조물의 염소이온 깊이와 깊이별 염소이온농도를 정량적으로 파악할 수 있다면, 구조물의 잔존수명을 사전에 비교적 정확하게 평가할 수 있다. 이러한, 구조물에서의 염소이온농도를 예측하기 위해서는 모델식의 개발이 필요하고 모델식은 정확한 현장데이타를 기반으로 한다.
