Water absorption of recycled aggregate is a characteristic by which this aggregate differs most from the aggregate obtained from natural resources. According to all available research in this area, it has been shown that recycled concrete aggregate has a significantly higher absorption level compared to natural aggregates. The reason for that is that the original cement mortar, which is an ...

30/05/2017 · 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 .
