Enhancing Crack Resistance and Strength of Recycled Aggregate Concrete with End-of-Life Tire Steel Fibers

Year: 2025

Type: article

Abstract: An increase in the use of recycled concrete aggregates (RCA) reduces concrete properties. Industrial fibers are proposed to enhance RCA concrete (RAC) but have production emissions and costs. Using waste fibers offers a sustainable solution. Recycled steel fibers from end-of-life tires are a viable option. This study evaluates the efficacy of end-of-life tire steel fibers (EFs) for RAC performance. Concrete with 75% RCA is investigated, with 0.60% industrial steel fibers (IFs) and EFs added. Compressive strength, energy absorption, toughness index, split tensile strength, and water absorption are evaluated. Results show that EFs enhance properties, suggesting potential for sustainable construction practices.
