The use of composite materials such as carbon fibre reinforced polymers in strengthening and repairing of structural elements, particularly those made of concrete, is widely spreading. However, for successful and cost-effective applications, researchers must improve their knowledge with respect to the actual behavior of strengthened structures. Therefore, carbon fiber reinforced polymers, because they are more cost effective, less time consuming than traditional retrofitting methods, can be considered as an alternative solution to repair and strengthen concrete members. The present study is conducted to examine the efficiency of CFRP in strengthened concrete beams in flexure. The investigation carried out has examined the flexural strength of both M20 and M40 concrete grades. The aim of this study was to regain the flexural strength of the damaged concert beam by wrapping with CFRP and to investigate if CFRP can be utilized for retrofitting and strengthening cracked beams. This experimental study revealed that the Concrete beams strengthened with CFRP are significantly improved in the resistance to loadings.
