An Experimental Analysis on Behaviour of Concrete with Copper Slag and Dolomite

Abstract

It is believed that concrete is the extensively used material next to water because of its versatility and it also leaves a carbon footprint on the environment during the manufacturing of cement, which is one of its main constituents. In the present scenario, sustainability is regarded as the need of the hour. In search of development of eco-friendly concrete, the acceptance of industrial by products in the modern concrete has gained the momentum. The study focusses on utilization of compatible materials with OPC concrete like copper slag and dolomite powder as a fractional substitute to the cement and fine aggregate accordingly in concrete. Copper slag is the derivative of matte smelting and refining of copper pyrites in the furnace. Dolomite powder was acquired from the mineral dolostone. The experimental research is made by in lieu of a 40% of fine aggregate (FA) with copper slag and cement is replaced with varying percentages of dolomite powder in 0%, 5%, 10% and 15%. The experimental investigations depicted that selected mineral admixtures enhances the strength and density of material, by lessening the pores count from durability test results. This study also helps to conclude that there are a few connected capillary pores in the cast specimens.
