The use of sustainable fibre reinforced polymers (FRP) for improving bending properties of concrete is becoming attractive, owing to the fact that they are environmental friendly. In this study, basalt fibre was used as reinforcement polymers in a simulated corroded concrete. Basalt fibre has adequate stiffness and strength-to-weight ratio, which showcase its potential as reinforcing material. The suitability of basalt fibre composites for strengthening corrosion inflicted RC beams was investigated, and comparative study was carried out between the unrepaired and control specimens. Experimental result shows that basalt fibre reinforced polymer (BFRP) strengthened specimens possessed higher load carrying capacity, energy absorption characteristics and increase of deflection values at higher loads when compared to control beams and unrepaired beams.
