Abstract
Finishing materials applied to reinforced concrete buildings are known for the improvement effects of durability of reinforced concrete, however, it is not clarified the chloride resistance effect. Chloride resistance of finishing materials is evaluated by apparent chloride diffusion coefficient generally, however, the evaluation methods have not been established. This study deals with the evaluation methods for apparent chloride diffusion coefficient of coating materials for textured finishes. We tried to evaluate by three methods which were literature survey, outdoor exposure test and salt water absorption test. As a result, we showed the extent of apparent chloride diffusion coefficient each type of coating materials for textured finishes. We also showed possibility to estimate the apparent chloride diffusion coefficient based on initial absorption rate of salt water absorption test and moisture permeability of the coating materials for textured finishes.
