| dc.description.abstract | These days, plastic wastes are the major environmental concerns that need rapid and continuous solution. These wastes have to be either recycled or converted to less harmful products. Apart from this, construction industry is growing with booming rate with high demand of construction materials. This thesis work is aimed to utilize plastic wastes of high density polyethylene as binding agent in the production of terrazzo tiles for out door applications. The significance of this study is that it can be used as input for policy makers and for future researchers around the topic. The production steps include: raw materials preparation, melting the plastic wastes, mixing molten plastic and sieved river sand and molding using hydraulic pressing machine. The single and the interaction effects of three process variables (percentage of plastic waste, sand particle size and pressing pressure) on the flexural strength of the terrazzo tiles were analyzed and discussed. The produced terrazzo tiles were analyzed for their physico-mechanical characteristics such as flexural strength, water absorption and surface morphology. The maximum bending strength of 20.7MPa was obtaianed at the optimum process variables (pressing pressure of 6MPa, plastic composition of 40% and sand particle size of 0.61mm). The maximum and the average water absorption of the tiles were 0.28% and 0.11% respectively. The pruduced terrazzo tiles have light weight but better physico-mechanical properties compared to conventional terrazzo tiles. These are good indicatives that show the produced terrazzo tiles can fit for the planned out door paving applications. Since the required properties are in the commonly exprienced range, it can be concluded that high density polyethylene plastic wastes can be used for the production of terrazzo tiles in the presence of the reinforcing river sand. Here, the plastic waste was used for binding purpose and it can be potential substitution for cement in the production of composite terrazzo tiles. | en_US |
