In the past two decades, the use of Near-Surface Mounted (NSM) Fibre Reinforced Polymer (FRP) strengthening technique has increased in the retrofitting of damaged structures such as buildings, bridges, storages, etc. In the NSM technique, epoxy resins are usually used as a bonding material and have an important effect on the bond performance between the FRP and concrete. Exposure of these resins to increment of temperatures (i.e. around or beyond the glass transition temperature, T-g) may lead to changes in their mechanical properties, so that the performance and effectiveness of the strengthening system can be affected.
