Abstract:

The feasibility of molten polyethylene terephthalate (PET) and laterite as composite for the production of masonry units was investigated. This aligns with the United Nations sustainable development goals of a cleaner environment, sustainable and affordable mass housing through innovative materials with low CO2 emissions. Using standard testing procedures, cubes of molten PET and laterite composite of 150 mm by 150 mm were used to assess the compressive strength of both the treatment and control groups. The treatment groups were formulated in mix ratios of 1:1, 1:1.5 and 1:2 of PET to laterite while the control group was made of 100% PET. The results recorded were 1.53N/mm2 for the control group, 4.7 N/mm2, 9.9 N/mm2 and 9.17 N/mm2 in ratios 1:1, 1:1.5 and 1:2. Furthermore, there was an upward trend in the density of the test cubes recorded as 15.30kg/m3, 16.6 kg/m3 and 17.4 kg/m3 for ratios 1:1, 1:1.5 and 1:2 respectively. However, despite the increase in density in ratio 1:2, there was a reduction in strength. This could be due to a trade-off in the bonding quality between PET and laterite at that ratio. Nevertheless, given the values of compressive strength recorded and the remarkable difference between the control group and the treatment group, there is are prospects of the suitability of the composite for sustainable building construction.
