Abstract

The effects of such environmental conditions as alkali media at temperatures of 23℃, 40℃, and 60℃ were investigated on the fiber reinforced polymer-to-concrete bond strength. For this purpose, 42 specimens were strengthened via the externally bonded reinforcement and the externally bonded reinforcement on grooves techniques. The specimens were later subjected to the single-shear test after the specified durations of exposure to an alkaline medium. The particle image velocimetry technique was used to investigate such bond characteristics of the strengthened specimens as load-slip behavior, strain profiles, and strain fields along the fiber reinforced polymer-to-concrete bond. Experimental results showed that the specimens strengthened via the externally bonded reinforcement on grooves method exhibited ultimate bond loads by up to 50% higher than those strengthened via the externally bonded reinforcement method.
