This paper talked about stress-strain curve of stirrup restraint ferrous tailing concrete by test and theoretical analysis. Twenty short column of 5 strength grade are contained in the test with WC30, WC35, WC40, WC45 and WC50. And the stress-strain data was achieved after the axial compression behavior test. Through the stress-strain curve, it can be found that the stress-strain relationship is similar with natural sand concrete. At the same time, it was put forward the whole stress-strain
