| Summary: | The main objective of this research is the formulation, and the rheological and mechanical characterization of steel fiber-reinforced self-compacting concrete (SFRSCC) based on an industrial by-product, marble powder. This study aims to develop a fiber-reinforced SCC with optimal rheological and mechanical properties. The rheological results of the SFRSCC indicate that the addition of steel fibers directly affects the workability of the mix, with this influence depending on the fiber dosage. Indeed, the introduction of fibers leads to a noticeable reduction in slump flow, along with an increase in flow time. Simultaneously, the mechanical results show a significant improvement in flexural strength and ductility as the fiber dosage percentage (℅f) increases. However, the compressive strength is only slightly affected by the increase in fiber dosage. Moreover, marble powder plays a crucial role in improving the flowability and stability of the SFRSCC. It enhances the mix’s compactness by filling the voids between aggregates, which promotes more homogeneous flow and reduces the risk of segregation. This synergy between steel fibers and marble powder optimizes the performance of SCC, making it suitable for various applications in the construction field. |
