Considering the economical and environmental aspects that have gained importance recently, the strengthening of the new and existing concrete structures has become an important upcoming alternative rather than demolishing and reconstructing. The deterioration and aging of concrete structures are not the only reason for strengthening; it can also be a faulty design or execution, upgrading design standards, increase in the load carrying capacity, accidents such as earthquakes and corrosion of reinforcements. The strengthening of structures implies repair and rehabilitation of the damaged existing concrete members, or retrofitting of a new structure or structure under service to improve its structural properties such as, strength, stiffness and so on. The traditional retrofit methods followed are concrete confinement and steel plate bonding to increase the load carrying capacity.
