Integrated Experimental Investigation on Sustainable Concrete Incorporating Ceramic Tile Waste and Recycled Rubber Aggregate as Partial Coarse Aggregate Replacement

The depletion of natural aggregates and the rise in construction and industrial waste demand sustainable alternatives in concrete production. This study investigates the performance of nominal mix concrete incorporating ceramic tile waste (CTW) and recycled rubber aggregate (RRA) as partial replacements (0–15%) for natural coarse aggregate. Fresh properties were evaluated using the slump test, while mechanical performance. was assessed through compressive strength tests at 7, 14 and 28 days using Compression testing machine(CTM). Results indicate that CTW improves compressive strength up to an optimum level due to better interlocking and bonding, whereas RRA reduces strength but enhances ductility and energy absorption. Hybrid combinations (CTW 5–7.5% and RRA 5–7.5%) showed balanced mechanical performance and improved toughness. The findings demonstrate that CTW and RRA can be effectively utilized in sustainable concrete for non-structural and semi-structural applications.
