This paper investigates for the first time the bond between TRM and concrete at high temperatures and, also compares for the first time the bond performance of both FRP and TRM systems with concrete high temperatures. Key investigated parameters were: (a) the strengthening systems (TRM and FRP), (b) the level of high temperature that the specimens exposed to (20, 50, 75, 100, and 150 0C) for FRP-reinforced specimens, and (20, 50, 75, 100, 150, 200, 300, 400, and 500 0C) for TRM-strengthened specimens, (c) the number of TRM/FRP strengthening layers. The results of high temperature testes showed that TRM system exhibited excellent bond performance with concrete than FRP system. In particular, TRM specimens maintained an average of 85% of their ambient bond strength when heated up to 400 0C, whereas the corresponding value for FRP specimens was only 17% when heated up to 150 0C.
