AbstractThis paper presents the test results of a study on the bond performance of near-surface mounted (NSM) basalt fiber reinforced polymer (BFRP) bars to concrete. Twelve C-shape concrete specimens were tested under direct pull-out loading configuration. Test parameters included the bar surface configuration (deformed and sand coated), the types of epoxy adhesive (NSM Gel and Sikadur-30), and the bonded length (6, 12, and 24 times its diameter). The influence of various parameters on the overall bond performance of NSM-BFRP bars is analyzed and discussed. The obtained results confirmed the impact of the investigated parameters on the bond behavior of the tested specimens. It was found that the bond strength and failure mode varied considerably with the bar surface configuration and bonded length. Higher bond strength was obtained when the NSM Gel epoxy with high strength properties. The results also revealed that both the deformed and sand coated bars showed almost similar bond strengths. Moreover, the pull-out loads increased with the increase of the bonded length of the NSM bars.
