The Impact of Elevated Temperatures on the Interaction of FRP Reinforcement and Concrete: An Experimental Study

This research focused on determining the interaction of FRP reinforcement and concrete under normal conditions and elevated temperatures. The specimens consisted of reinforcement embedded into a concrete block and loaded with tensile force. Specimens representing extreme conditions were placed in a furnace and exposed to elevated temperatures. Three types of composite rebars with different properties were tested. The results of the experiments confirm a significant reduction in bond of composite rebars, which, at higher temperatures, can lead to a sudden loss of bond between the rebar and concrete.
