Abstract :

Materials such as carbon fie composite (CFC), aramid fie composites (AFC), and glass fie composites (GFC), can be used in the repairing and strengthening of aged concrete. In the present paper, experimental study is designed to investigate the flexural behaviour of reinforced concrete beams strengthened with CFRP GFRP laminates attached to the bottom of the beams, sides of the beams by epoxy adhesive subjected to transverse loading. The experiment consists of varying the fiber content; configuration and their performance in flexure were studied. From the test results it can be concluded that retrofitting with GFCL and CFCL provides a feasible rehabilitation technique for repair as well as strengthening. The paper also highlighted the beams failure modes due to the different level of strengthening scheme.
