Making Of Floor Tile By Using Waste Glass As Partial Replacement Concrete Aggregate

Abstract

Concrete is most widely used man made construction material and its demand is increasing day by day. In order to make concrete industry sustainable, the use of solid waste materials in place of natural resources is one of the best approaches. Waste glass is a major component of the solid waste stream in many countries. It can be found in many forms, including container glass, flat glass. In Ethiopia the problems and impacts of solid waste materials has become one of the major environmental, economic, and social issues. The main objective of this project was to produce floor tile by using waste glass as a partial replacement of concrete aggregate (25%, 50%, 75% and 100%). The main significant of this project is to contribute to the construction industry in saving the environment, to encourage the government to find solutions regarding the disposal to landfills of waste materials and to find the alternative aggregate resources from local waste glass materials. The scope of this project were intended to produced floor tiles by using of waste glass as partial replacement with color full and the durability of its at least without losing of the standard and this project was cover the amount of waste glass in Adama city. In this project, the research or the data collection was only focused on broken bottles in specific enterprises or excluded any bottles in residencies and other type of glasses. Concerned of this data above 286 tons waste glass/broken bottles/ are generated from enterprises per year. For to produced of the waste glass floor tile(20×20×2cm) should be used fine waste glass and natural aggregate, ordinary Portland cement, sand, water, plasticizer admixtures materials and equipments. The experimental method process was included the percentage of waste glass used to replacement of the aggregates in making tiles and compared the compressive strength of the existing and new tiles. For this reason number of samples were manufactured and tested, each has a different percentage of waste glass and added plasticizer admixture for only 50% of waste glass fine aggregate. The result of the project was shown when the % replacement of waste glass aggregate increased their water absorption and compressive strength was decrease. It concluded that floor tile make from waste glass could be give environmental, social and economic advantages. It is recommended to extend research on the area of recycling and reusing techniques of waste glass materials in building construction to induct or introduce feasibility studies, including cost/benefit and payback period analysis for each technique
