Bond characteristics of concrete made of recycled ...

The recycled aggregate concrete performed better than the natural aggregate concrete in terms of normalised bond stress. Lowering the water–binder ratio has the effect of increasing the bond stress and slip values. With the increase in bar diameter and embedment length, a decrease in bond stress and increase in slip can be observed. An equation to determine the bond stress is proposed based ...
