- Synopsis
- Carbon fiber sheet adhension method is used as repair/strengthening method of concrete structures. However, delamination of sheet is pointed out as a problem in an adhesion method. On this account, flexible layer which is superior in transformation ability is installed between concrete and carbon fiber sheet, and various kinds of loading examination were performed. As a result, flexible layer improved an adhesion property of carbon fiber sheet, and delamination resistance was improved. In this paper, examination results of strengthening of beam, slab and pipe, prevention of dropout of concrete are reported.
