Now a days, many of these structures have reached the end of their planned service life. Therefore there is a need for repairing and rehabilitation to strengthen the structures. A technique used for strengthening concrete structures is retrofitting. In this paper, retrofitting is done by wrapping and strengthening the concrete surface by Glass Fiber Reinforced Polymer sheet (GFRP) using binders. In this work two types of binder are used namely epoxy and cementitious composites. Generally epoxies have a good bonding capacity and also good approach to strengthen the structures, but have some drawbacks in form of incompatibilities with the base concrete. To overcome this, new class composite called Mineral based composites are being used. From the result, it was concluded that compressive strength and stiffness for concrete using MBC as binders are comparable with epoxy binders apart from being economical and nonhazardous. It also inferred that strength increases with increase in number of layers of wrapping.
