Abstract
All over the world the concrete structure elements require rehabilitation or strengthening at certain times due to
different reasons as Errors in planning or construction, increasing the service loads and others. In the last few
decades the common material used for strengthening of concrete structural elements was fibre reinforced
polymers FRP due to it`s High strength-to-density ratio, high levels of stiffness and chemical resistance. This
paper presents the different techniques of strengthening of reinforced and pre-stressed concrete structural
elements using FRP materials, the procedures of strengthening as surface preparation, adhesive curing and
discuss the different modes of failures. This technique eliminates or reduces the crack width and growth rate,
delay initial cracking, increase the flexural stiffness deflection and extend the fatigue life of RC beams. The best
strengthening option in this case is pre-stressed carbon fibre reinforced polymer (CFRP).
