Concrete may be defined as a concrete which has closely – spaced special Transverse reinforcement which restrains the concrete in directions perpendicular to the applied stress. The maintenance and upgrading of structural members is perhaps one of the most crucial problems in civil engineering applications. The objective of this research was to determine the mechanical properties of cubes, beams and cylinders on applying GFRP. The size of the cube is taken as 150mm x 150mm x150mm, of beam is taken as 1500mm x 100mm x 200mm, and that of cylinder as 300mm x 150 mm. The mix design M25 ratio was formulated and specimens were casted. The GFRP was applied on 28 days cured concrete specimens. A relation between mechanical strength and age of specimens is also arrived. From the test results it is concluded that the mechanical strength increases by using GFRP confinement.
