Book excerpt: An experimental study on the simulation of corrosion in a large-scale reinforced concrete column and their repair using carbon fibre reinforced polymer (CFRG) sheets is presented. Seven columns were subjected to an acclerated corrision regime, wrapped using CFRP sheets, then tested to structural failure and (or) subjected to further post-repair accelerated corrision, monitoring, and testing. Accelerated corrision was achieved by adding sodium chloride to the mixing water, applying a current to the reinforcemednt cage, and subjecting the specimens to cyclic, wetting and drying. Results showed that the CFRP repair greatly improved the strength of the repaired member and retarted the rate of post-repair corrosion. Moreover, subjecting the repaired column to extensive, post-repair corrosion resulted in no loss of strength or stiffness and only a slight reduction in the ductility of the repaired member.
