Comparative Study on Test Method of Compressive and Flexural Characteristics of Structural Adhesives for FRP Composites used in Strengthening RC Members

구조보강용 FRP 함침.접착수지의 압축.휨 특성치 시험방법 비교 연구

Pull-off test is generally used as a method of evaluating bond strength of FRP with concrete at the job site. However, pull-off test damages FRP composites and the maximum pull-off strength is limited up to tensile strength of concrete. Accordingly, it is required to set-up a test method that can simply evaluate bond performance of structural adhesive. This study suggested compression and bending test of epoxy resin as test methods that can indirectly evaluate performance of adhesive, as well as standardized test specification for different types of specifications from various countries. In this study, the section dimension of compression and bending test specimens is unified, and standard test specimen size is achieved by test results.
