Suitability of using post-consumer polyethylene terephthalate wastes in cement-based hollow sandcrete blocks

Abstract In recent times, efforts are channeled towards limiting the impact of waste plastic pollution on environment. This study examines beneficial utilization polyethylene terephthalate (PET) wastes, which is a non-biodegradable materials as partial substitute for sand in production non-load bearing hollow sandcrete blocks. The physical and mechanical properties such density compressive strength blocks using PET replacement fine aggregate at 5%, 10%, 30% 50% were determined. Tests results show that produced decreases content increases. Results showed varied from 1391.33 kg/m 3 50%PET to 1954.54 5%PET content, while reference was 2002.15 7 days. values densities ranged between 1453.88 1851.09 5% 1991.77 28 also demonstrate similar reduction trend 1.140 N/mm 2 2.564 1.510 2.991 respectively, curing age increases block containing an optimum percentage with comparable conventional will help mitigate menace marine promote responsible consumption.
