According to the abstract released by the Intellectual Property India: "Experimental Study on The Behaviour of Steel Fiber Reinforced Concrete Abstract Concrete is one of the most widely used construction materials; however, its brittle nature and low tensile strength limit its performance under dynamic, impact, and flexural loading conditions. Steel Fiber Reinforced Concrete (SFRC) has emerged as an effective solution to enhance ductility, crack resistance, and post-cracking behavior of conventional concrete. This study presents an experimental investigation on the mechanical and durability characteristics of SFRC with varying steel fiber volume fractions. Concrete specimens were prepared by incorporating hooked-end steel fibers at different percentages by volume (0%, 0.5%, 1.0%, 1.5%, and 2.0%). Standard tests were conducted to evaluate compressive strength, split tensile strength, flexural strength, impact resistance, and toughness characteristics. Workability was assessed using slump tests, while hardened concrete properties were analyzed at 7, 14, and 28 days of curing. The results indicate that the inclusion of steel fibers significantly improves tensile and flexural performance compared to conventional concrete. An increase in fiber content enhanced crack-bridging capability, reduced crack propagation, and improved energy absorption capacity. The compressive strength showed moderate improvement, whereas split tensile and flexural strengths demonstrated substantial increases. However, excessive fiber content led to reduced workability and challenges in uniform fiber distribution. The study concludes that an optimal fiber dosage exists that balances strength enhancement and workability. Steel fiber reinforcement effectively transforms brittle concrete behavior into a more ductile response, making it suitable for applications such as pavements, industrial floors, bridge decks, precast elements, and seismic-resistant structures. The findings contribute to improved material design strategies for high-performance and impact-resistant concrete structures."
