![]() ![]() The flexural behaviors of the beams during the complete loading procedure were experimentally studied under a four-point bending test. ![]() With a varying volume fraction of steel fiber from 0% to 2.0%, 10 beam specimens were produced. The properties of SFR-CRAC have been comprehensively improved by using steel fibers. The composite-recycled aggregate has features of the full use recycled fine aggregate and small particle recycled coarse aggregate, and the continuous grading of coarse aggregate ensured by admixing the large particle natural aggregate about 35% to 45% in mass of total coarse aggregate. To promote the engineering application of recycled aggregate for concrete production with good adaptability and economic efficiency, this paper performed a campaign to investigate the flexural performance of steel fiber reinforced composite-recycled aggregate concrete (SFR-CRAC) beams matched with 500 MPa longitudinal rebars. ![]()
