| Résumé : |
The escalating environmental impact of non-biodegradable waste, particularly from discarded tires, necessitates innovative recycling strategies. This study explores the potential of incorporating pre-treated crumb rubber from waste tires into concrete mixtures as a sustainable alternative to traditional coarse aggregates. A comprehensive experimental investigation was conducted to evaluate the fresh-state properties, workability, and mechanical behavior of rubberized concrete. The study focused on varying proportions of pre-treated rubber particles, substituting 10%, 20%, 30%, and 40% of conventional coarse aggregates by volume. These rubber particles were treated with cement paste to enhance bonding strength within the composite material. Standard tests were employed to assess the properties of the rubberized concrete, including density, slump, and compressive strength. The findings reveal that the incorporation of recycled tire rubber as a partial aggregate replacement notably impacts the workability and mechanical properties of the concrete. However, this reduction is mitigated when a concrete superplasticizer is utilized. Furthermore, the research indicates a decrease in the failure load of rubberized concrete composite slabs, ranging from 15% to 58%, compared to those constructed with traditional aggregates. Additionally, a significant reduction in the initial cracking load was observed. These outcomes offer critical insights into the structural and mechanical implications of using pre-treated rubber particles in concrete. While the decrease in mechanical performance poses challenges, the study illuminates pathways for enhancing the sustainability of concrete through the innovative reuse of waste materials. This approach not only addresses environmental concerns but also opens new avenues for the development of more sustainable construction materials. |
