Evaluation of Bond Strength for AFRP Reinforcing Bars in Columns with Self-Consolidating Concrete
Previous research and design codes have focused on developing equations, mostly empirical based on experimental studies, to determine the bond strength of steel bars with different types of concrete. However, limited studies have been conducted on FRP bars particularly embedded in self-consolidating concrete (SCC), but very few using aramid fiber reinforced polymers (AFRP) bars. This investigation aims to study the influence of two main parameters: (1) superplasticizer dosage and (2) water to cement ratio on the bond strength and bond slip model of the AFRP bars and SCC. Results show a significant effect of superplasticizer on the bond strength of AFRP bars embedded within SCC. Moreover, the effect of the w/c ratio is quantified and its correlation with bond strength is presented. The slippage of the AFRP bars embedded in the concrete was accurately measured to determine a precise bond-slip model that is compared to conventional concrete performance.
