        abstract = {This study examines the incorporation of crumb rubber in M25 grade concrete to enhance sustainability and evaluate its suitability for earthquake-resistant applications. Waste rubber from discarded vehicle tires was used as a partial replacement for natural aggregates. Four mixes were prepared: conventional concrete (CC), crumb rubber as fine aggregate (CRFA), crumb rubber as coarse aggregate (CRCA), and crumb rubber replacing both aggregates (CRFC). Mechanical tests including compressive strength, split tensile strength, and flexural strength were conducted to assess performance variations due to rubber substitution.
The overall results show a marginal reduction in strength when crumb rubber is introduced. Among the modified mixes, the CRCA mix exhibited superior performance in maintaining strength. These enhanced deformation properties are crucial under seismic loading, where the ability to dissipate energy and limit structural damage is essential. Additionally, using crumb rubber contributes to environmental sustainability by recycling waste tires and reducing the demand for natural aggregates.
The findings indicate that the CRCA mix offers an optimal balance of mechanical performance, flexibility, and eco-friendliness, making it the most promising candidate for further research in sustainable and earthquake-resistant concrete construction.},
