| Abstract |
Diffusion-Reaction Carbonation Model on the base of FEM was developed to predict the carbonation depth of the paint coated concrete structure. The diffusion and solubility coefficient of the coated film used in this study were estimated by the differential pressure-CO2 permeability device. The Diffusion-Reaction Carbonation Model constructed in this study was validated by the accelerated carbonation test using concrete specimens applied with organic coats. The CO2 diffusion coefficient of acrylate was the highest, followed by epoxy, polyurethane, polyvinyl chloride in this study. Effects of the degradation and the number of coatings have also been analytically examined. |
