State-of-the-art review of FRP strengthened RC slabs

Many concrete structures are getting weakened or collapsed due to corrosion of steel reinforcement in structures and other factors. Rehabilitation and strengthening of concrete structures with FRP (Fibre Reinforced Polymers) has been a useful technique since last few years. FRP sheets or plates are very suitable for strengthening not only because of their strength, but also due to the simplicity in the application. In this review paper, different strengthening techniques using FRP and other materials are reviewed. It can be concluded from the literature review that FRP is one of the efficient option for strengthening in either of the case like increasing the load carrying capacity of structures or to restore the original capacity of the structure after distress due to any means.
