摘要：Objectives: This research deals with the study of the flexure behaviour of beams reinforced with Basalt bars in contrary with the steel bar reinforced beams and comparing the stress strain behaviour and strain characteristics. Methods: Basalt bars commonly known as Basalt Fiber Reinforced Polymer (BFRP) is an innovative component, and hence the differences and limitations of their bondage with concrete in structural members in comparison with conventional steel reinforcement of RCC members are identified. The project presents some experimental results of research by considering a flexural member (beam), reinforced with basalt bars, in contrary with the nominal steel reinforced beams and testing under loading frame of 500 kN capacity. The two grades of concrete involved are M30/40, while the reinforcement are done with 8 mm diameter basalt rebars and subjected for flexural strength evaluation. The various deflection patterns and nature of crack formation has been illustrated. The results incorporate the difference in the load-deflection pattern of BFRP beams with that of nominal control beams with steel reinforcement. Applications/Improvements: This approach of BFRP reinforced beams can be effectively used in severe exposure conditions like marine conditions and areas prone to acid attacks due to their improved durability and strength characteristics.
