Copper Slag, Micro Silica, Compressive Strength, Split Tensile Strength, Flexural Strength


The replacement of natural resources in the manufacture of cement and sand is the present issue in the present construction scenario. Copper slag is industrial by-product materials produced from the process of manufacturing copper and Micro Silica is by product of the Ferro - silicon Metal industry. Use of Copper slag and micro silica does not only reduce the cost of construction but also helps to reduce the impact on environment by consuming the material generally considered as waste product. Hence in the current study an attempt has been made to minimize the cost of cement and crushed sand with concrete mix grade M40 by studying the mechanical behavior of this concrete mix by partial replacing with advanced mineral admixtures such as Copper slag and micro silica in concrete mix. In this study, partial replacement of Cement with micro silica and crushed Sand with Copper Slag considered. Experimental study is conducted to evaluate strength characteristics of hardened concrete, properties of concrete have been assessed by partially replacing cement with micro silica, and crushed sand with Copper Slag. The cement has been replaced by micro silica accordingly in the range of 0% (without micro silica), 4%, 12%, and 20% by weight of cement for M40 mix. The crushed sand has been replaced by Copper slag accordingly in the range of 0% (without Copper slag), 5%, 10%, 15%, and 20% by weight of cement for M40 mix. Concrete mixtures were produced, tested and compared in terms of compressive, flexural and split tensile strength with the conventional concrete.
