摘要：

Contemporary construction practices increasingly recognize the utilization of waste materials as a methodological imperative for mitigating waste accumulation and advancing environmental remediation. This article explores the incorporation of waste glass granules as a partial substitute for coarse aggregates in conventional concrete, maintaining an equivalent coarse aggregate size range (9.5–12.5 mm) while varying the replacement ratios, specifically 5%, 10%, 20%, 30%, and 50%. The study investigates the impact of this substitution on key concrete properties, including compressive strength, flexural strength, density, water absorption, and permeability. The findings reveal that the utilization of waste glass granules, possessing a higher density compared to the original coarse aggregate, leads to an increase in the overall concrete density. Furthermore, the incorporation of glass granules enhances concrete impermeability and reduces water absorption. However, it is observed that the introduction of waste glass granules has an adverse effect on both compressive and flexural strengths of the concrete, with the magnitude of this effect escalating with higher replacement rates. The study identifies that the optimal replacement rate for waste glass granules, with minimal impact on concrete strength, stands at 15%. © 2024, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
