Environment Friendly Alternative Substitutes Iron Slag and Copper Slag in Concrete Construction Design and Characterization

Abstract

The demand for concrete is constantly growing with the increase in infrastructure newlinedevelopment. The production of Portland cement is a highly energy intensive process newlinewith the involvement of significant amount of non-renewable natural resources. Besides newlinethe energy consumption, cement manufacturing process also contributes to substantial newlineCO2 emission due to calcination contributing to the greenhouse gas emission and newlinesubsequent global warming. Also, the environmental issues arising as a result of mining newlineof natural sand for the construction industry have led to a pressing need for finding an newlinealternate solution since the availability of natural resources are decreasing tremendously newlineand also inflicting irreversible damages to the environment. Research work has been newlineinitiated to address these issues by exploring possibilities of utilizing industrial wastes newlineslags as an environment friendly alternative and sustainable construction material for newlineGreen concrete. newlineIron slag (I-sand) generated as a by-product in iron and steel industries, is usually newlinedisposed by delivering to landfills. Effective utilization of iron slag in cement concrete newlinecould offer a sustainable solution for the aforementioned waste disposal with the added newlineadvantage of conservation of natural resources and as an economically viable alternative. newlineIn the current scenario where the availability of natural sand has diminished considerably newlineand the excessive exploitation is leading to environmental problems like sliding of river newlineshores, climatic changes, global warming etc., possibility of replacing river sand with Isand newlinein concrete manufacturing could be a possible alternative.
