The use of natural aggregates is increasing day by day due to the new innovations and development taking place in the construction field. Because of these reasons the reuse of demolished constructional waste came into existence so that the solid waste can be minimized thereby reducing the scarcity of natural aggregates. Currently, about 33 million tonnes of copper slag is being generated yearly worldwide. Among that about 6 to 6.5 million tonnes is being contributed by Construction works. Copper slag, an abrasive blasting grit made of granulated slag is gaining importance these days. This work makes use of using copper slag as a replacement for the fine aggregate, M-sand. Rice Husk Ash which is one of the main waste product from agricultural field is also used here along with copper slag. The work also checks on the suitability of using Rice Husk Ash in construction field. The use of these wastes from agricultural and industrial field helps to reduce manufacturing costs as well as the selling price which makes it affordable. Moreover, the problem of disposal of the waste can also be minimized to a certain extend. The work also focuses in analyzing and comparing the strength of the manufactured tile with that of ordinary tile. For this four different mixes were prepared by adding copper slag in proportions of 25%,20%,15% and 10% and rice husk ash in proportions of 5%,10%,15%,20% respectively, keeping an equal percentage of 40% clay and 30% red soil in almost all mixes. Experimental investigation like Compressive strength test, Flexural strength test, Water absorption test were carried out for all the prepared mixes. Variations in the experimental results for these different mixes were studied and thus the most suitable and effective mix out of these which can be used for making roofing tile was identified. Keywords—Copper slag, Rice Husk Ash, Compressive strength, Flexural strength , Water absorption
