Experimental Investigation of Copper Slag as Partially Replacement of Fine Aggregate and Fly Ash as Cement in Concrete

Merugumala Mosheraju | Sambangi Arunchaitanya

Abstract: The foremost neutral of this study was to identify marginal source of good quality fine aggregates which is exhausting very fast due to the fast pace of construction activities in India. Use of copper slag is a surplus material of copper production and fly ash is a surplus material of power plants provides great prospect to utilize it as an alternative to normally available aggregates and cement. For this work M30 grade concrete was used and tests were conducted for a variety of proportions of copper slag replacement with fine aggregate of 0 to 50 % and fly ash replacement with cement of 0 % to 25 % and also the tests were conducted to the durability properties of the working concrete. The fine aggregate was replaced with copper slag as proportions of 0 %, 10 %, 20 %, 30 %, 40 %, and 50 % and cement was replaced with fly ash as proportions of 0 %, 5 %, 10 %, 15 %, 20 % to 25 % in OPC 53 grade cement. The obtained result was compared with those of control concrete made with Ordinary Portland Cement (OPC) and also finding the mechanical properties of concrete like compressive, split tensile, flexure strengths. The results indicate that compressive and flexural Strengths is increased due to high stiffness of copper slag.
