염해에 대한 콘크리트 구조물의 내구성 향상 최근 연구 동향

Abstract

In this study, the latest research trend about the improvement in durability of concrete structures to damage from salt-attack was investigated. In Korea, after inserting the contents about durability in the KCI standard in 1999, research on durability evaluation was done actively, Moreover, after a housing performance grade system performs in 2006, it is judged that research on evaluation of durability is done actively, On the other hand, in the research on chlorine ion diffusion into concrete, research in consideration of the time dependability and the finish material of a diffusion coefficient is advancing. Also, the research on the measure of re-degradation of the concrete after repair or evaluation of the durability ability of repair material is demanded. Moreover, the research on LCC evaluation is advancing to repair of a concrete structure,
