Flexural performance of RC beams with near surface mounted CFRP plate under tropical climate effects / Nauwal Suki

Environmental factors are one of the reasons for structural deterioration. Deteriorated structures are required to be strengthened and rehabilitated so that it can continue to stand strong throughout its service life. This study focuses on determining the flexural performance of RC beams longitudinally strengthened with CFRP plate using Near Surface Mounted (NSM) method with the effect of tropical climate. Tropical climate parameters such as the air and moisture will recommence the carbonation process. Through carbonation process, the carbon dioxide will gradually penetrates the concrete surface and react with moisture and calcium hydroxide forming calcium carbonate that leads to steel corrosion and weaken the structure. The utilization of CFRP composite materials using NSM method is an alternative to strengthen the structures as it is rust proof and stronger in term of stiffness compared to steel.
