Studying The Strength And Durability Properties Of Steel Fiber Reinforced Self -Compacting Concrete

Abstract

This study investigates the strength and durability characteristics of steel fiber reinforced self-compacting concrete (SFRSCC). The primary objective is to evaluate the influence of varying steel fiber contents on the mechanical performance and durability performance of self-compacting concrete. Tests conducted include compressive strength, splitting tensile strength, flexural strength, water absorption, sorptivity, and resistance to chloride ion penetration. The experimental results demonstrate that the inclusion of steel fibers significantly enhances the tensile and flexural strengths, improves the concrete's crack resistance, and reduces permeability, thereby augmenting its durability. The findings suggest that steel fiber reinforcement is an effective method to improve the structural integrity and longevity of self-compacting concrete in various construction applications. The optimal fiber content balancing workability, strength, and durability is also discussed, providing valuable insights for structural engineers and material scientists aiming to design durable, high-performance concrete composites.
