Strengthen concrete columns by using FRP

Several methods for preventing corrosion of steel in reinforced concrete have been developed and used,among which epoxy coatings on joints, polymer injection into concrete surfaces and cathodic protectionof joints can be mentioned. However, each of these methods has been somewhat successful, so for thecomplete removal of the corrosion problem, the researchers have focused on replacing steel bars withnew corrosion-resistant materials. One of the techniques used today to increase the tensile strength ofconcrete is coating of concrete with polymeric FRP layers.
