Abstract :

Fibre Reinforced Polymer Composites (FRPC) are widely used for retrofitting of deteriorated Reinforced Concrete (RC) in structural applications. The deterioration of beams has occurred due to several factors such as corrosion, lack of bonding strength, seismic activity and ground motion. The rehabilitation and retrofitting are done using several techniques and FRPC is most efficient method because of higher strength/ modulus and low weight with higher corrosion resistant and design flexibility. The structural members are failed due to surface cracks and deterioration of concrete because of sudden application of lateral load such as seismic and wind forces. The polymer composites are possessed high stiffness, high strength, better fatigue performance and corrosion resistance. In this research, mechanical properties of epoxy/basalt fibre polymer composite surrounded reinforced concrete column are investigated. The basalt fibre is surrounded the reinforced concrete in three different layer thickness and the thickness of Basalt Fibre Reinforced Polymer Composites (BFRPC) are 2 mm, 4 mm and 6 mm. The Scanning Electron Microscope (SEM) is utilized for confirming the uniform dispersion of basalt fibre in epoxy resin. The 2 mm, 4 mm and 6 mm thickness BFRPC are subjected to flexural test, tensile test and hardness test to analyze the mechanical properties. The mechanical characteristics, include hardness, flexural strength and ultimate tensile strength of BFRPCs are higher than the basalt unreinforced concrete.
