An Experiment Study of Concrete Caste with River Sand and with Varying Sizes and Percentages of Steel and Nylon Fibers

Abstract:

This research paper presents the findings of an experimental study conducted to investigate the influence of varying sizes and percentages of steel and nylon fibers on the mechanical and durability properties of concrete. The objective of this study was to explore the potential enhancements in concrete performance through fiber reinforcement, considering the two distinct fiber types - steel and nylon. A comprehensive testing program was devised, encompassing a wide range of fiber combinations to assess their individual and combined effects on concrete properties. The concrete specimens were prepared by incorporating different sizes (length and diameter) and proportions (percentage by volume) of steel and nylon fibers into the concrete mix. Mechanical properties, including compressive strength, tensile strength, and flexural strength, were evaluated to determine the impact of fiber reinforcement on the concrete's load-bearing capacity and resistance to cracking. Additionally, the durability properties, chloride ion penetration, and abrasion resistance, were assessed to understand the potential improvement in the concrete's long-term performance under adverse environmental conditions. The experimental results revealed significant variations in the mechanical and durability properties of the fiber-reinforced concrete compared to the conventional concrete mix. Steel fibers demonstrated superior performance in enhancing the concrete's load-carrying capacity and ductility, especially at higher percentages. On the other hand, nylon fibers exhibited exceptional resistance to and abrasion, contributing to improved durability. Notably, the steel and nylon fibers exhibited synergistic effects, leading to a balanced enhancement of mechanical and durability properties. In conclusion, this study provides valuable insights into the benefits of incorporating steel and nylon fibers in concrete, offering an effective means of optimizing the material's overall performance for diverse engineering applications. The results from this research can serve as a basis for developing more resilient and sustainable concrete structures, which can withstand harsh environmental conditions and contribute to the advancement of construction practices. Further exploration into the long-term behavior and cost-effectiveness of fiber-reinforced concrete is recommended for a comprehensive understanding of its feasibility in practical engineering applications.
