Abstract

In this study, we carried out outdoor exposure test of concrete specimens with coating materials for textured finishes including repair specification in order to make clear the deterioration of coating materials and aging of the protective effects on deterioration of reinforced concrete structure. These specimens were exposed to Ishikari, Tsukuba, Tokyo and Okinoerabu. According to the results, it was not observed the difference of deterioration in coating materials between primary specification and repair specification. The gloss retention was affected by coating material type. We proposed estimation methods on change of gloss retention, Cl- diffusion coefficient and CO2 diffusion coefficient based on the test results.
