| Abstract |
In this study, for the establishment of the performance evaluation methods and the quality control standards of durability recovery method, the quantitative exposure data by long term exposure test under the coastal and normal atmosphere environment is accumulated and analyzed. Investigating and evaluating the result of exposure test during 54 months of exposure age, micro crack, swelling and spalling of surface coating material, crack of repair boundary parts and the great potential difference between repair part and non-repair part were somewhat generated. But carbonation depth and chloride-ion penetration depth very little penetrated than cover depth and it seems reasonable to conclude that main cause of corrosion of reinforcing bar are macro cell from the result of corrosion area.Therefore, it is considered to be applied as the fundamental data on the performance evaluation and quality control standards of repair material and method through continuous exposure test in the future. |
