N2 - Using steel rebars in reinforced concrete structures is the most common practice nowadays. However, the increase in steel price, its weakness against corrosion, its weight, and its unavailability as an exhaustible natural resource push to use other strengthening solutions. The first usage of fiber-reinforced plastics composites is used as reinforcement for rehabilitating concrete structures. The composites are thin plates bounded to the surface of the concrete. For new constructions, some structural design standards detail the method used to design structures reinforced with composite bars such as Glass Fiber Reinforced Plastics rebars (GFRP) and Basalt Fiber Reinforced Plastics rebars (BFRP). This paper proposes a new reinforcement rod based on Alfa natural fiber. Numerical models, analytical models, and laboratory tests were conducted to study the effectiveness of these reinforcing rebars. The results on 4 cm × 4 cm × 16 cm specimen beams show that the beams reinforced with 2 bars of 4 mm in diameter have strength more significant than the unreinforced control beams. With reinforcement, the bending strength increases. These results on test specimens validate the proposed innovation based on the Alfa Fiber Reinforced Plastics rebars (AFRP) rebar.
