Abstract—The objective of this research work is to reinforced concrete beams with Carbon Fiber Reinforced Polymers (CFRP) and subject them to a flexural test. For this purpose, two concrete mix designs of 210 and 280Kgf/cm2 were made and CFRP was applied to them. A total of 12 specimens were made for each mix design and reinforced with 1/4", 3/8" and 8mm steels. It was concluded that the addition of CFRP as well as the stressing of different steel diameters improved the reinforced concrete beams in terms of flexural strength, cracking pattern, stiffness and ductility of all beams, compared to the beams without CFRP and steel reinforcement.

Index Terms—CFRP, reinforced concrete, flexural strength
