ABSTRACT
Cement concrete reinforced with steel bars is an extremely popular construction material. One major flaw, namely, its susceptibility to environmental attack, can severely reduce the strength and life of these structures. External reinforcement using steel plates have been used in earlier attempts to rehabilitate these structures. The most important problem that limited their wider application is corrosion . Recent developments in the field of Fiber Reinforced Composites (FRCs) have resulted in the development of highly efficient construction materials. The (FRCs) are unaffected by electro-mechanical deterioration and can resist corrosive effects of acids, alkalis, salts and similar aggregates under a wider range of temperatures. Reduced material cost, coupled with labor savings inherent with its low weight and comparably simpler installation, relatively unlimited material length availability, and immunity to corrosion, make FRP materials an attractive solution for post strengthening, repair, seismic retrofit, and infrastructure security. This technique of rehabilitation is very effective and fast for earthquake affected structures and retrofitting of structures against possible earthquakes.
