This study also contributes to reducing environmental pollution caused by plastic and glass waste as well as current construction brick production methods. The results show that the bulk density, compressive strength, and bending strength of brick samples made from PET plastic and glass waste are higher than those of burnt clay brick samples, while water absorption is much smaller than that of burnt clay brick samples.
