Crack obeying ability of coating material and Increasing in fatigue life of coated marine concrete

콘크리트용 코팅재의 구열추종성과 그 적용에 의한 해양콘크리트 구조의 피로수명 증가

This paper deals with the obeying ability to the crack of waterproof membrane (produced from polybutadiene- or epoxy type resine) under static and repetitive loading, and an increase in fatigue life of marine concrete structure by applying the waterproof membrane. From experimental results, it is cleared that the obeying ability for crack under repetitive loading is smaller than that under static loading. With regard to fatigue life, the use of membrane possessed large obeying performance under repetitive loading results in significantly increase in fatigue life of marine concrete structure
