대기노출실험을 통한 구조용 강재의 부식 손상 평가

다국어 초록 (Multilingual Abstract)

The corrosion damage of the structural steel can be occurred depending on various environmental factors such as temperature, humidity and airborne salt and even if they are the same steel grade, their corrosion rate can be changed by their exposed atmospheric corrosion environment. In this study, atmospheric exposure test was performed to evaluate the corrosion damaged rate of the structural steel depending on the exposed environment condition with different corrosion location. From exposure test results, the mean corrosion depth and corrosivity grade of the structural steel were evaluated depending on the exposure period. Using the regression curve calculated by the mean corrosion depth achieved from the atmospheric exposure test results, corrosion damage rates of the structural steel were compared and analyzed depending on exposure test location.
