An experimental investigation of bond strength of AFRP bars with self-consolidating concrete
This investigation aims to study the effect of varying superplasticizer dosage and water-to-cement ratio (w/c) on the bond strength between aramid fiber reinforced polymers (AFRPs) bar and self-consolidating concrete (SCC). A total of 15 compression tests and 36 pullout tests are conducted on AFRP and steel bars within five different groups of concrete mixtures. Results show a significant effect of superplasticizer and water-to-cement ratio on the bond strength of AFRP bars embedded within SCC. The bond-slip behavior between the AFRP bars and SCC was quantified and is presented in this research.
