Development of Analytic Model for Estimation of the Carbonation Depth Considering the R.H. in the Concrete

콘크리트 내부 상대습도를 고려한 탄산화 깊이 산정 수치해석 모델 구축

The purpose of this study is to evaluate the depth of carbonation considering the relative humidity in concrete using the FEM model. The difference of relative humidity in concrete has not been considered in calculating the carbonation depth in analytic model. That reason can make the over estimation in expectation of RC structure durability. The temperature and R.H. expectation model and the carbonation depth expectation model are development in past author's studies. The two models are coupled in this study. The fact that there is the difference between actual environment and acceleration test is revealed from FEM numerical analysis.
