A REVIEW ON FLEXURAL STRENGTHENING OF REINFORCED CONCRETE BEAMS WITH PRESTRESSED NEAR SURFACE MOUNTED CFRP LAMINATE

Reinforced structures are subjected to tremendous loading, which causes early deterioration, and replacing RC structures on before the end of intended life is prohibitively expensive. The application of fiber-reinforced polymer (FRP) composites to strengthen damaged structural components is obtaining favour in the construction industry because to their better strength, durability, and compatibility with reinforced concrete structures during usage. The main purpose of this research is to examine the existing performance, problems, and further potential of CFRP-strengthened reinforced concrete structural member under various loading circumstances. FRP reinforcement outperforms in static, dynamic, and harsh environmental criteria. The most typical type of failure in reinforced beams are debonding, separation of concrete cover, and FRP rupture. Acceptance and usage of FRP in RC structure strengthening will increase further as new techniques for utilising the full strength of FRP, reducing brittleness, fire risk and damages due to accident, lowering energy consumption and during production emission of carbon, and finally reducing the initial cost are developed. This report identifies knowledge gaps as well as promising research topics for FRP-strengthened structures.
