In order to study the bond-slip performance between brick-rich recycled concrete and steel bars, 48 brick-rich cube specimens were tested through pull-out test. The effects of the cube compressive strength of recycled concrete, the shape of steel bar and the reinforcement diameter on the bond performance were studied. The results show the greater the strength value of recycled concrete, the larger the load value corresponding to the unit slip value, and the steeper the load-slip curve; when the strength and the reinforcement diameter are constant, the bonding stress of deformed steel bar (HRB400 grade steel) is about 1.55-1.75 times of Light round bar (HPB300). Lastly, through detecting damage by ultrasound, the bond-slip constitutive model considering damage between recycled concrete and steel bars was proposed.
