Enhancing high-performance concrete sustainability: integration of waste tire rubber for innovation.

This study extensively explored the impact of integrating waste tire rubber into high-performance concrete (HPC) by substituting natural sand. Different fractions of rubber particles-5%, 10%, and 15% replacements of the fine aggregate-were rigorously investigated. Properties from fresh to hardened concrete were assessed, including compressive and tensile strength, modulus of elasticity, workability, and damping coefficient.
