摘要

The evolution of building materials and technologies is imperative in response to the growing demands for large-scale infrastructure. Steel fiber-reinforced concrete (SFRC) has gained widespread usage due to its notable benefits, such as enhanced crack-bridging capacity and increased shear strength, reducing the need for traditional reinforcement. This study investigates the effects of varying fiber content and compaction times on the mechanical properties of SFRC. Laboratory tests were conducted on 24 different concrete mix designs, producing a total of 216 specimens, including blocks, cubes, and beams. The findings indicate that the optimal fiber content and compaction time significantly influence the compressive, flexural, and tensile strengths of SFRC. A detailed mathematical and statistical analysis highlights the importance of these parameters, providing insights for optimizing SFRC performance in construction. Future research directions are suggested to enhance further the understanding and application of SFRC in the construction industry.
