In order to promote the effective utilization of recycled concrete materials,the relationship between flexural strength,splitting strength,steel fiber content and recycled aggregate content of steel fiber recycled concrete is analyzed by design experiments,and the regression equation is constructed to clarify the relation-ship between flexural strength and splitting strength.The test results show that the flexural strength and split-ting strength of the material will decrease when the content of recycled aggregate is increased,and the flexural strength and splitting strength will be reduced by 12%~28%and 9%~16%when 100%recycled aggregate is added;When mixed with 1%steel fiber,the flexural strength is increased by 16%~40%,and the splitting strength is increased by 13%~23%;Steel fiber is the key reason for the improvement of flexural strength and splitting strength of steel fiber recycled concrete.
