In this article, the effect of replacing cement with silica fume and fine aggregate with copper slag has been investigated. For this research work, concrete of M40 grade is prepared and evaluated for fresh and harden concrete properties such as compressive strength, tensile strength and flexural strength. Further, the cement is replaced with silica fume at 0, 2, 4, 6, 8 and 10 % and fine aggregate replaced with copper slag at 0, 10, 20, 30, 40 and 50 %. Compressive strength, strength and Flexure strength have been tested. It is observed from the results that the use of silica fume and copper slag as partial replacement material improves mechanical properties of the concrete. Concrete with 40 % copper slag and 8 % silica fume shows better performance among all the mixes.

Concrete plays an important role in every construction. This paper is an experimental investigation to study the mechanical properties of the concrete with partial replacement of cement by dolomite powder and fine aggregate by copper slag. So, in this investigation, by usage of Dolomite powder in concrete on one side improves density and other side improves strength and hardness. Copper slag also increases density of concrete and toughness of concrete. The cement content replaced with dolomite and fine aggregate replaced with copper slag from 5% to 25% at regular intervals of 5%. In the designed mix proportion of M30 grade concrete is 1:2.17:2.95. The Superplasticizer Master Rheobuild 920SH of 0.5% dosage used as chemical admixture is added to the concrete to maintain 0.45 the water-cement ratio. The concrete cubes, cylinders were casted. The different mechanical properties like compressive strength, split tensile strength, flexural strength were tested after 3 days, 7 days and 28 days of curing from 5 to 25% at regular intervals of 5% replacement of cement with dolomite powder and 10% to 50% at regular intervals of 10% replacement of fine aggregate with copper slag.

Abstract: This research focuses on studying the effect of Mild Steel Scrap and Crusher Dust on the Properties of Concrete Mixes as a partial replacement of Sand. The trend of mixing several kinds of additional materials such as Glass powder, plastic, Quarry dust, Copper slag, Steel scrap, in building engineering is now growing. Consumption of Crusher dust and Mild steel scrap are one of the lively research area that include the effectiveness of replacement in all the aspects of construction materials. It is very significant to develop eco-friendly concrete from ceramic waste. This Research deals with the experimental study on the mechanical strength properties of M20 grade concrete with the partial replacement of fine aggregate by using crusher dust and mild Steel Scrap. In order to analyze the mechanical properties such as Compressive Strength, Spilt tensile strength, and Workability the samples were casted with mild steel scrap having constant proportion of 5% and crusher dust having 10%, 15% ,20% 25%, 30%, 35%, 40% partial replacement. In second category sand has been partially replaced by mild steel scrap proportion of 10%, 15%, 20%, 25%, 30%, 35% and crusher dust by 20%, 25%, 30% 35% at a different periods of curing 7 days, and 28 days. The optimal of percentage addition of Crusher dust and Mild steel scrap are analyzed considering the needs of mechanical properties of concrete.
