Abstract In order to protect the environment and bridge the gap between demand and supply of bricks, different waste materials have been utilized to replace either soil, sand or water in the production of bricks. The primary objective of the present study is to manufacture a composite brick from waste materials, without adding any soil or water. Melted polyethylene terephthalate (PET) and Polypropylene (PP) bottles were mixed with MSW ash, stone dust and glass bottles powder Silicon Dioxide (Silica) in varying percentages by weight for the manufacturing of bricks. Various physical, mechanical and micro-structural investigations were carried out on the composite brick to observe the effect of these properties on the behaviour of brick under different weathering conditions. The microscopic images taken through scanning electron microscope (SEM) revealed that the presence of micro-voids and cracks affects the structural density and efficiency of brick, which ultimately impacts the compressive strength and water absorption of brick. The compressive strength of 11.57 N/mm2 was achieved by composite brick, which was 12.19 % higher as compared to conventional brick having a compressive strength 11.02 N/mm2 whereas the water absorption of composite brick was 0.75 % which was 92.46% lower as compared to conventional brick having a water absorption 11.48 %. The study concluded that composite plastic bricks, which address both the need for building materials for construction and municipal plastic waste (MPW) reduction, can be one of the biggest developmental goals of the world that encourages sustainability and environmental safety.
