ABSTRACT: The
present work investigated the effect of polyethylene terephthalate (PET)
plastic waste on the physico-mechanical and thermal properties of
cement-stabilized laterite bricks to see the durability of the modified bricks
(CSLB). Samples were formulated by mixing laterite, cement, and different
percentages of PET (0%, 3%, 5%, and 7%) by volume. The bricks were produced
using the M7MI Hydraform standard interlocking block and kept in the shade for
a curing period of 28 days. The addition of 3% to 5% PET to the laterite
stabilized with 10% cement results in a decrease in both dry and wet
compressive strength, which is determined
using the Controlab compression machine. However, the obtained results
are in concordance with the standards. The thermal conductivity of CSLB, determined using the box method with the EI700
measurement cell, decreases as the PET content of the mixture increases.
A decrease in bulk density from 1.67 to 1.58 g/cm3 was observed.
