Abstract
This study investigates the bond–slip behavior of glass fiber-reinforced polymer (GFRP) bars embedded in concrete and exposed to alkaline environments at different temperatures. Although GFRP reinforcement is increasingly adopted for its corrosion resistance, the long-term bond performance of the bar–concrete interface in high-pH conditions is still not fully understood. To help close this gap, a comprehensive database of 84 pull-out tests from the literature was assembled, focusing on three key parameters: bar surface configuration, exposure duration, and conditioning temperature. The comparative analysis highlights the dominant role of surface treatment in bond degradation and reveals substantial variability…
