Through the method of reinforced electrifying corrosion,three points loaded test were carried out on 12 recycled aggregate concrete beams with 100% coarse aggregate replacement rate and different corrosion rate,and the effect of mechanical properties under the same strength conditions of different steel diameter and corrosion rate of recycled aggregate concrete beams were analyzed.Results show that when the steel corrosion rate is less than 10%, the bond strength of steel and recycled concrete beams sufficient to ensure that both can work together,and the test beams occurred damage mode of material strength ;when the steel corrosion rate is greater than 10%,the bond strength of steel and recycled concrete beams insufficient to ensure that both can work together,and the test beams occurred damage mode of bond failure.Based on ANSYS finite element software with different reinforcement corrosion rate of recycled concrete beams simulation analysis, and the load-stress curve of the cross section of the corroded reinforced recycled concrete beams were checked, through the finite element results compared with the test results, verify the reliability of the finite element analysis model.
