Abstract: The main objective of this project is to study the mechanical properties of copper slag as a partial replacement of fine aggregate for manufactured sand (m-sand) at different proportions (0 %, 10 %, 20 %, 30 %and 40 %) of Copp1er Sla1 g. Copp2er sla8 g is the alternative material resulted during the process of matte smelting and improving the copper. To obtain 2.2-3 tons of copper slag about 1 ton of co5pper is required. Whereas quarry dust or stone dust which is producing during quarry activity and it is a by-product material. in this project we are using completely manufactured sand (m-sand). In the present investigation it is proposed for the using of factory waste materials which has encouraged in construction industry for production of concrete as it contribute in the reduction of usage of artificial sources. For this research work, M30 grade concrete was used and tests were conducted. Various concrete mixtures were prepared with different proportion of copper slag as fine aggregates replacement. Concrete mixtures were evaluated for workability, compressive strength, splitting tensile strength and mortar compressive strength after 7, 14, and 28 days at ambient room temperature curing. The result for concrete indicted that workability increases with increase in percentage of copper slag. A substitution of about 20 % of copper slag as a fine aggregate gives higher compressive and split tensile strength and is case of the mortar cubes the higher strength for compressive and split tensile was obtained at the 40 % replacement of copper slag as fine aggregate.
