Abstract:
Plastic is one of the daily increasing useful as well as a hazardous material. At the time of need plastic is found to be very useful, but after its use, it’s simply thrown away, creating many kind of hazards. This paper presents the use of plastic waste as a binding material instead of cement in the manufacturing of road tiles and changing of the waste plastic in to something beautiful and useful. The raw materials used in this project are PE (polyethylene), PET (polyethylene terephthalate) and aggregate. Waste plastic disposed to the environment is highly composed of PET and PE. In this study the optimum proportions of plastics PE, PET and aggregate ratio which gives optimal quality of the final tile is analyzed and also this optimization considers the cost of raw materials. The process starts with collecting, sorting, chopping and crashing of waste plastics. Then the plastic is melted in a metallic container, aggregate is then added gradually up on vigorous mixing into the melting plastic. It has been found that a proportion of 80% of aggregate and 20% of plastic (5% of PE and 15% of PET) resulting an optimal quality and cost effective product with compressional strength of 11.14 MPa. This product has also water absorption of 1.17% of its total weight, density of 1900 Kg/m3 and roughly efflorescent test of less than 10% of its original surface color.
