해양환경하의 콘크리트 구조물에 대한 내구성 평가 = Evaluation on Durability of Concrete Structures under Marine Environment

다국어 초록 (Multilingual Abstract)

Sevice life of concrete structures that are exposed to the marine environment, is largely influenced by the corrosion of reinforcing bars due to the chloride contamination. Chloride ions penetrate continuously into concrete from enviroment, and chloride diffusion velocity is governed by a mechanical steady state. In this study, to be estimate durability of concrete structures under marine environment, The tests of concrete compressive strength and corrosion of reinforcing bars on concrete specimens carried out. The experimental parameters are the water-cement ratio, the ratio of blended slug, the ratio of blended CSA, and the curing method.
