| Abstract |
There are a lot of reports about the cover concrete falling by the reinforcement bar corrosion which is generated by deterioration factors, such as, CO2, chloride ion, sulfuric acid etc. through the cover concrete and crack of it. This study is about one of the reinforcement methods, continuous fiber sheet method, adapted to degraded RC structures. The performance of Dry Type Vinylon Sheet Method and Dry Type Composite Method which take relatively short time and are cheap to practice was evaluated by tensile test, tensile-shear test and push out test. The performances were compared with the existing Wet Type Vinylon Sheet Method. The predictive model based on the elastic dynamic was proposed. Weatherability of continuous fiber sheet methods was verified by the accelerated deterioration test. |
