| Abstract: | The growing demand for vehicles has spurred an increase in tire production. However, the improper disposal of these waste tires poses a significant environmental and health hazard. To address this, recent research has explored the integration of recycled steel fibers (RSF) and crumb rubber (Cr) from used tires into concrete formulations to create innovative rubberized and fibrous concrete. A notable study specifically examined the impact of adding RSF of varying lengths and a fixed volume fraction into rubberized concrete containing different proportions of Cr, where Cr partially replaced natural sand. Through the fabrication and testing of 18 reinforced concrete columns under axial compression, the findings demonstrated that RSF alone significantly enhanced the concrete’s properties, including density, compressive strength, and tensile strength, by remarkable percentages of 100.27%, 116.84%, and 107.25%, respectively. Conversely, the exclusive use of Cr resulted in a decline in these properties as its content increased. Notably, the "Co5" columns, which incorporated RSF into a concrete mix containing Cr, exhibited superior performance, showing improved displacement and ductility by a degree of approximately 44.67% and 15.65%, respectively, alongside a significant reduction in crack widths by about 29.45% compared to standard rubberized concrete (Co1&Co2). The properties and attributes of columns display promising performance as well as displacement and ductility when RSF is incorporated into concrete mix that includes Cr compared to rubberized concrete.
