In order to use glass powder steel slag recycled concrete in building structures, improve the recycling rate of industrial waste, and reduce environmental pollution, this paper replaces part of cement with glass powder and steel slag instead of some fine aggregates. The effect of glass powder steel slag is studied by ANSYS finite element simulation. Influence of self-compacting recycled concrete beams on flexural performance. The research result suggested: at the initial stage of cracking, the mid-span moment and mid-span deflection of C1, C2 and C3 groups of beams constructed with recycled concrete incorporating milled glass and steel slag were significantly improved compared with those of baseline group of beams and with increasing steel slag, their mid-span moment was not much changed but mid-span deflection was increased; at the yield stage, the mid-span moment and mid-span deflection of C1, C2 and C3 groups of beams constructed with recycled concrete incorporating milled glass and steel slag were significantly improved compared with those of baseline group of beams and were further increased with increasing steel slag. In this paper, the bending performance of the beam is best when 20% glass powder is used instead of cement and 80% steel slag is used instead of fine aggregate.
