Durability of Protective Surface Coatings Exposed in Marine Environment for 3 Years

해양환경에 3년간 노출시킨 콘크리트 표면도장재료의 내구성 평가

Protective surface coating for concrete is available for applying to concrete structures for protecting chloride attack. However, the useful data obtained from real marine environment for surface coating materials is not sufficient yet in Korea and thus the engineers face many difficulties to apply the coating method in durability design. Surface-coated concrete specimens were fabricated and installed around the piers of Seohae grand bridge to observe long-term performance in actual marine environment. In this study, the results of durability of surface coatings for 3 years were reported.
