Abstract:

To address the excessive accumulation of plastic waste and incineration ash from domestic refuse, this study explores their use in tile manufacturing. The goal is to optimize manufacturing conditions—mixing temperature, mixing time, and compression force—using the Box-Behnken design and Response Surface Methodology (RSM). Tiles were produced at temperatures of 200, 210, and 220°C, with mixing times of 10, 15, and 20 minutes, and compression forces of 120, 135, and 150 tons. The results showed high coefficients of determination (R²) for compressive strength, flexural strength, and surface abrasion resistance, with an average error of less than 5%. The optimal conditions identified were a mixing temperature of 210°C, a mixing time of 15 minutes, and a compression force of 135 tons, yielding tiles with a compressive strength of 18.25 MPa, a flexural strength of 10.10 MPa, and a surface abrasion resistance of 0.02 g/cm².
