Abstract
Concrete production is highly resource-intensive and contributes substantially to environmental degradation due to its reliance on natural aggregates and Portland cement. This study investigates the feasibility of using waste ceramic tiles (WCT) as a sustainable replacement for conventional coarse aggregates in concrete production. Concrete specimens of Grade 15 were produced with a 1:2:4 mix ratio and water–cement ratio of 0.6, incorporating WCT at replacement levels of 0–100%. Physical properties of aggregates, including specific gravity, bulk density, and water absorption, were assessed, along with compressive strength and density of concrete at curing ages of 3, 7, and 28 days. Results showed that increasing WCT content reduced both density and compressive strength; however, prolonged curing improved performance. At 100% replacement, concrete achieved a 28-day compressive strength of 15.8 N/mm², meeting the BS 8110-1 (1997) requirement for structural concrete and classifying as lightweight concrete per ASTM C138/C138M. These findings confirm the potential of WCT as a viable, eco-friendly aggregate for selected structural and non-structural applications, contributing to sustainable waste management and resource conservation in construction.
