Investigation on effectiveness of NSM CFRP Vs EBR CFRP for strengthening concrete members

Abstract

This paper is based on literature review on Carbon Fibre Reinforced Polymers (CFRP) materials used as near surface mounted (NSM) reinforcement in order to strengthen Reinforced Concrete (RC) structures. Rehabilitation of structures is a complicated task that has been made simple by the utilization of CFRPs. Out of the two methods of externally bonded reinforcement (EBR) and near surface mounted (NSM) reinforcement it has been proven that NSM methods provides better results. This paper presents alternative methods that can be used to improve the bond performance of NSM CFRP on RC structures. It also highlights research gaps that need to be addressed in order to sharpen the knowledge and improve the common practices of CFRPs.
