Bond behaviour of normal/recycled concrete and corroded steel bars
Highlights Bond degradations of normal and recycled concrete non-stirrup specimens are similar. Stirrups effectively increase bond capacity of reinforced concrete. Stirrups reduce difference of bond behaviour between normal and recycled concrete. The parameters of steel stress transfer and bond stress distribution are defined. Stress–slip relationships are different at each location along steel bar.
Abstract Pullout and beam tests were performed to study the bond behaviour between normal aggregate concrete (NAC) or recycled aggregate concrete (RAC) and corroded steel bars. The results show that the corrosion-induced bond degradation characteristics of NAC and RAC pullout specimens are similar. For specimens with stirrups, the ultimate bond strengths of both NAC and RAC specimens do not change significantly with steel corrosion growth; the stirrups reduce the difference in bond behaviour between NAC and RAC specimens. Stress transfer in steel and bond stress distribution parameters were defined to characterise the bond behaviour. The bond stress–slip relationships were observed to vary between different locations.
