Abstract

This study evaluates an alternative solid waste management option for Low-Density Polyethylene (LDPE) waste commonly called “pure water sachet” as partial replacement of sand in concrete. Three mix ratios of 1:1:2, 1:1.5:3, 1:2:4 were used while the LDPE waste materials were obtained from within University of Lagos campus, in Lagos State of Nigeria. The pulverized LDPE plastic waste, with compacted and uncompacted bulk densities of 362.9 kg/m 403.23 kg/m3 respectively, could be classified as an ultra-lightweight fine aggregate in terms of bulk density. The bulk density of the plastic concretes produced using 1:1:2, 1:1.5:3 and 1:2:4 range between 2417.78-2548 kg/m3, 2348.63-2589.63 kg/m3, 2429.63-2424.6 kg/m3, respectively with compressive strength range of 22.64-34.26, 20.47-27.32 and 20.21-27.47 N/mm2 and could be classified as normal-weight concrete which meets the minimum compressive strength for use as lightweight aggregate in plain concrete (7N/mm2). The optimum and preferable mix is 1:1:2.
