Comparative study on the strength properties of paving blocks produced from municipal plastic waste

In this study, municipal plastic waste is used in producing paving blocks. Binders the form of melted bottles (Polyethelene Terephthalate (PET)) and water sachets (High Density Polyethylene (HDPE) with river sand, were making Mix ratios; 1:1, 1:1.5 1:2 sand-plastic considered. Sand-cement mixes adopted as controls. 230mm x 140mm 55mm blocks cast, cured at ambient temperature tested for 72-hours absorption 21 days compressive strength. 3 specimen prepared each mixture. Sand-HDPE mix produced stronger than sand-PET sand-cement mixes. Topmost strength 17N/mm2 was generated from sand-HDPE 1:2. Sand-PET should be avoided since they generate very low strengths. Sand-plastic melt faster higher temperatures. Therefore, can only light load pavements not subjected to high temperature.
