An overview of bond behavior of recycled coarse aggregate concrete with steel bar

Abstract In this paper, an overview focusing on the bond behavior of recycled coarse aggregate concrete (RAC) with steel bar is carried out. The results show that failure modes RAC specimen were not only influenced by a single factor, it necessary to comprehensively consider influence various factors specimen; diameter, cover diameter ratio and replacement rate RCA all affect load-slip curve Bond strength predictive equations bond-slip relationship models has been summarized ensure engineers better understand their applicability; influencing specimens including RCA, compressive strength, type embedment length performance; freeze-thaw cycles corrosion bar. When damage bars reach certain degree, deteriorates.
