Abstract: This paper enumerates the effectiveness of externally bonded Hybrid Fiber Reinforced Polymers (HyFRP) laminates on reinforced concrete beams for flexural strengthening. A total of 5reinforced concrete beams of size 150 x 250 in cross section and length of 3000mm were considered in this study. All the beams were tested in four-point bending over a simple span of 2800 mm. Of the above five beams, one beam served as reference beam and the other four beams were HyFRP laminated. The variables considered in this study included thickness of HyFRP laminate and composite ratio. Adequate measurement was acquired on load and deflection characteristic of HyFRP strengthened as well as reference beam
