Partial Replacement of Sand by Crusher Dust and Mild Steel Scrap in Concrete
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.
