Abstract
Durability and sustainability are critical objectives in modern concrete research due to the increasing demand for cost-effective and environmentally friendly construction materials. While incorporating waste steel fibers into concrete has shown promise in enhancing mechanical properties, their impact on durability requires further investigation. This study evaluates the durability performance of high-performance concrete (HPC) reinforced with waste steel fibers sourced from building waste and recycled tires. Key durability parameters, including sorptivity, chloride penetration, and carbonation resistance, were analyzed under aggressive environmental conditions. Advanced characterization techniques, such as Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA), were employed to assess mass loss and provide insights into material behavior. The findings contribute to a deeper understanding of how waste steel fibers influence the long-term performance of sustainable concrete materials.
