Investigation of the Performance of Basalt Rebar’s as Reinforcement in Concrete Beam

Abstract

Abstract Now a day’s concrete is the main component in the construction. The tensile strength, ductility, and crack resistance of plain concrete are low. Fiber rebar reinforcing material possesses high tensile strength, non-corrosive, thermally resistant, alkaline resistant, and is cost-effective, making it a good material for concrete reinforcement. The basalt rebar is the new virgin material with enhanced the characteristics and strength. In this paper mechanical properties of basalt rebar, flexural performance of concrete beams reinforced by varying the ratio of flexural reinforcement such as 0.2%, 0.4% and 0.6% of basalt rebar compared to reinforced with steel and also ductility of beams was studied. The results showed that deformations of concrete beams with basalt rebar have three to four time more than the beams with steel. The characteristic of flexibility in the RC beams caused the difference to drop to 40% at the last stage of loading. Theoretical moment capacity is calculated by using IS 456:2000, at 0.4% reinforcement, the experimental and theoretical moment capacity of S3 and BR3 are nearly same. But in 0.2% and 0.6% of reinforcement for conventional and basalt RC beams varies. By increases the percentage of reinforcement in basalt reinforced concrete beams with increased in ductility of the beam and also deformation.
