The rapid development and continuous innovations in the construction industry have resulted in a significant increase in the consumption of natural aggregates. At the same time, a substantial quantity of solid waste is generated from construction and demolition activities. These issues have encouraged the reuse of construction and demolition waste, particularly materials such as waste ceramic tiles and granite powder, as an effective approach to reducing solid waste and minimizing the depletion of natural aggregates used in concrete production. Ceramic tile waste is generated not only from the demolition of buildings but also during the tile manufacturing process. Studies indicate that approximately 20–30% of the material produced in tile manufacturing industries is rejected as waste. Therefore, the utilization of this waste material can help address the shortage of natural aggregates while simultaneously reducing the environmental impact associated with construction waste disposal.

 

In the present study, crushed waste ceramic tiles, ceramic tile powder, and granite powder were utilized as partial replacements for coarse and fine aggregates in concrete. Waste ceramic tiles were used to replace coarse aggregates at replacement levels of 10%, 20%, 30%, 40%, and 50%. In addition, fine aggregate was partially replaced by 10% granite powder and ceramic tile powder, along with the use of ceramic tile aggregates as coarse aggregate. M25 grade concrete was designed and experimentally investigated. Different concrete mixes were prepared by replacing coarse and fine aggregates with crushed ceramic tiles and granite powder at various proportions. The prepared concrete specimens were evaluated for workability, compressive strength, split tensile strength, and flexural strength after curing periods of 7, 14, and 28 days.

 

The experimental results indicated that the incorporation of ceramic tile waste and granite powder influenced the workability and strength characteristics of concrete. An improvement in the strength properties of concrete was observed with the incorporation of ceramic coarse tile aggregate, with the optimum enhancement being reported at a replacement level of up to 30%. The study demonstrates that waste ceramic tiles and granite powder can be effectively utilized as alternative aggregate materials in concrete, thereby reducing the consumption of natural aggregates and contributing to sustainable construction practices.
