Abstract—External wrapping with Fibre Reinforced Polymers (FRP) has been increasing in recent years for strengthening and retrofitting of concrete and steel structures. Hence an attempt has been made to investigate the compressive behavior of concrete specimens (cylinders) strengthened with FRPs. The parameters varied in this investigation were wrapping materials (which include glass and carbon fibre reinforced polymers), number of plies (single and double plies), orientation of fibres (along the length and circumference of the specimens) and curing period (wrapping after 7 and 28 days of water curing). The experimental result shows that the specimens wrapped with carbon fibre reinforced polymers have higher compressive strength than the specimens wrapped with glass fibre reinforced polymers in both single and double plies for wrapping after 7 and 28 days of water curing.
