UTILISING PET PLASTIC AND GLASS WASTE IN MANUFACTURING OF MASONRY BRICKS

Abstract

Nowadays, the manufacturing process of burnt clay masonry bricks causes serious environmental pollution such as loss of agricultural land, climate change. Besides, PET plastic and glass waste also cause serious problems for the environment. Therefore, we reuse PET plastic and glass waste to produce masonry bricks aiming to minimize the environmental harm caused by burnt clay bricks and these wastes.  Different PET plastic/glass mass ratios are performed to produce masonry bricks. The brick samples are evaluated for bulk density, compressive strength, bending strength, water absorption and compared with burnt clay brick samples. 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. The best brick sample in this study is the M37 sample with a compressive strength of 33.9 MPa which is 3 times higher than the burnt clay brick samples.
