초록

철근콘크리트는 철근과 콘크리트가 재료적으로 일체화되어 경제적이고, 반영구적 이여서 사회 간접자본으로 건설되는 교량 및 대형구조물에 사용되어 지지만 해양노출환경 및 동절기에 사용되는 제설제 등으로 콘크리트 중의 염화물 이온이 철근의 부동태 피막을 파괴하여 철근이 부식함으로써 여러 가지 화학적 및 물리적 작용을 복합적으로 받을 경우에 단기간에 내구성능이 저하되고 구조물의 수명이 단축된다. 본 연구에서는 상기와 같은 철근콘크리트의 염해에 의한 손상부에서 염소이온을 효과적으로 제거하여 초기 구조물의 내구성을 회복할 수 있는 보수 공법에 대한 연구를 수행하였다.

Reinforced concrete is used for bridges and large structures that are constructed with social overhead capital because they are economically and semi-permanently integrated with reinforcing bar and concrete. However, when the chloride ion in the concrete destroys the passive film of the reinforcing bar by the marine exposure environment and the snow remover used in the winter season, and the reinforcing bar is corroded by various chemical and physical actions, the durability is deteriorated in a short period, and the life span is shortened. In this study, a repair method to recover the durability of the initial structure by effectively removing chloride ion from the damage caused by salting of the above mentioned reinforced concrete was conducted.
