Steel Fibre Reinforced Concrete

Abstract: Steel Fibre Reinforced Concrete (SFRC) has emerged as a promising composite material that significantly enhances the mechanical properties of conventional concrete. By integrating discrete steel fibres within the cementitious matrix, SFRC exhibits improved tensile strength, toughness, and crack resistance, addressing many of the inherent weaknesses found in plain concrete. This paper investigates the influence of fibre content, aspect ratio, and distribution on the structural behavior of SFRC under various loading conditions. Experimental results are compared with theoretical predictions and existing design standards to assess the material’s performance in real-world applications. Particular attention is given to the post-cracking response, which demonstrates how fibre reinforcement contributes to energy absorption and ductility. The findings suggest that SFRC holds considerable potential for applications requiring high durability and resilience, such as in pavements, industrial flooring, and seismic zones. This study aims to contribute to a more nuanced understanding of SFRC, encouraging further exploration into its optimization and implementation in modern construction practices.
