Assessment of Strength Enhancement and Structural Performance in Fiber-Reinforced Concrete with Varying Fiber Types and Percentages

Abstract This study focuses on the strength-enhancing capabilities of three types of fibers: steel fiber, polypropylene fiber, and asbestos fiber, which are commonly used to improve the tensile strength, durability, and load-bearing capacity of concrete structures. Each fiber type offers distinct advantages based on its physical and chemical properties. Steel fibers, for instance, are known for their high tensile strength and ability to resist cracking, while polypropylene fibers enhance the ductility and impact resistance of concrete. Asbestos fibers, though less commonly used due to health concerns, have been historically known for their fire resistance and high tensile strength.The study also explores the effects of varying fiber percentages on the mechanical behaviour of concrete structural members. By incorporating different fiber volumes into the concrete mix, the research aims to optimize the balance between strength and workability. Experimental analyses conducted on test samples reveal that the type and percentage of fiber used play a pivotal role in enhancing the overall performance of concrete. The results underscore the importance of selecting the appropriate fiber type and percentage to meet specific structural requirements.
