The combination of fibre-reinforced poly mer (FRP) and high-volume fly ash self-compacting concrete (HVFA-SCC) reinforced is expected to solve the problem of steel corrosion in traditional structures and develop sustainable infrastructures. Bond beha viour has a strong effect on serviceability of FRP reinforced concrete structures. To achieve the accep tance of this novel composite structures in practical construction and design, it is significantly important to investigate the bond behaviour of FRP reinforced HVFA-SCC. In this study, a series of pull-out tests were carried out to investigate the bond behaviour of HVFA-SCC reinforced by FRP bar, which included bond strength, bond-slip response, and failure mode. The investigated experimental variables were
