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 coast is accumulated and analyzed. Investigating and evaluating the result of exposure test at 24 month of exposure age under the coastal environment,carbonation and salt damage are not happened at all but the difference in electric potential are found. 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.

Among durability of concrete, the carbonation process corrodes bar makes progress slowly by the diffusions of CO<sub>2</sub> from surface of concrete. This carbonation process is affected by both the concrete factors such as W/C ratio, types of cement and aggregate, admixture types and the environmental factors such as CO<sub>2</sub> concentration, temperature, humidity and so forth. especially the carbonation process is closely related to CO<sub>2</sub> concentration and Air permeability. therefore This study is to examinis affected by relationship with Air permeability Coefficient and CO<sub>2</sub> diffusion Coefficient Have an Effect on carbonation in reinforced concrete As a results of this study, we have come to make a sense of an available correlation with Air permeability Coefficient and CO<sub>2</sub> diffusion Coefficient.
