Recently, it has been reported that the corrosive damage of concrete structures occurs at many waste water treatment facilities. In order to prevent this problem, FRP lining is being applied on the concrete surface. In this application, the lined FRP should show a fairly high adhesive strength to the concrete surface. Generally a Kenken-type adhesive strength tester is used to evaluate the adhesive strength between them. But it was revealed that this method could not evaluate such an adhesive strength precisely. Therefore, in this report, it has been studied to develop a new practical way to evaluate this adhesive strength. In this new method, the real adhesive strength between lined FRP and cement mortar was measured in such a way that only a vertical peeling force was loaded to the end of the FRP. The results obtained were discussed in terms of stress intensity factor K as a fracture mechanical parameter.
