To Investigate the Properties of Concrete Having Partial Replacement of Fine Aggregate with Copper Slag and Coarse Aggregate with Ceramic Tile Waste

Abstract

Abstract: The process of smelting copper produces copper slag as a by-product. The disposal of such a massive volume of copper slag raises environmental concerns. So, recycled copper slag can be utilised in place of fine aggregate or cement. This has several benefits, including lowering disposal costs and increasing recycling rates. In terms of coarse aggregates, their supply is a serious challenge in the construction industry. As a result, ceramic tile waste can be used as a coarse aggregate substitute. They are tough, long-lasting, and resistant to degrading forces. Ceramic tile wastes are simply leftover tiles from construction projects. Waste generated during building and demolition activities accounts for over 70% of all waste worldwide. Furthermore, approximately 60% of the waste generated during the creation of tile is discarded. As a result, discarding such a large amount of rubbish causes environmental issues. Concrete costs are lowered when they are used. The results of an experimental inquiry into the impact of partially substituting fine aggregate with copper slag and coarse aggregate with ceramic tiles waste on the strength properties of concrete are presented in this study. Utilizing 150x300mm cylindrical specimens for split tensile strength research and 150x150x150mm cubes for compressive strength testing. As the amount of ceramic waste in the mix rose, the concrete's workability, density, compressive strength, and flexural strength all decreased. The mix M5 had a compressive strength of 44.40 N/mm2 after 28 days of curing. Ceramic waste is porous and lighter than conventional coarse aggregate, resulting in lower density and strength. This study shows that ceramic waste may be utilised for both structural and non-structural purposes.
