| Conditions such as the execution of repair works and ambient environment can affect the protective performance of surface coating material for concrete structures, and they are important in terms of exhibiting a long-term repair effect. This paper presents a fundamental study on the influence of film thickness and ambient temperature to the protective performance of surface coating material: oxygen, moisture vapor and chloride ion permeability. It was confirmed that as film thickness and ambient temperature increased, oxygen, moisture vapor and chloride ion permeation rates decreased and increased, respectively. Test results showed a good agreement with the behavior of polymer molecule membrane. |
