Due to their superior performance as reinforcing material for restoration projects, Fibre Reinforced Polymer (FRP) composites are widely used in Civil Engineering. In this study, first, the basic tests were performed on the materials and based on its properties the mix design arrived for M30 grade of concrete. Fresh and hardened tests were conducted to evaluate the performance of concrete. An experimental investigation was performed on Reinforced Concrete (RC) beams improved in flexure with FRP composites, with carbon and glass fibre in the form of sheets. Five RC beams will be cast and tested using a 4-point bending configuration. The steel reinforcement ratio used for designing RC beams is 0.419%. The thickness of FRP laminates were the main varied test factor used in this investigation. In this paper, one of the five beams is a control beam, while the other four were strengthened using FRP laminates. The findings demonstrated that using FRP laminates effectively upgraded the load-bearing capability of the RC beams. However, using thicker FRP sheets to increase strength is not advised because flexural strength is controlled by epoxy properties and concrete surface quality. The ductility of the strengthened beam using thicker FRP sheets leads to failure during an earthquake.
