Bond strength between recycled aggregate concrete and …

After one end of the rebar is buried in the recycled aggregate concrete mix and cured for a particular time, it becomes resistant to being pulled out when an external force F is applied to the other end of the rebar. This indicates the existence of forces acting at the interface between recycled aggregate concrete and rebar, i.e., bond stresses [35].
