Abstract :

<p>&nbsp;Natural resources are depleting worldwide while at the same time the generated wastes from the industry are increasing substantially. The sustainable development for construction involves the use of nonconventional and innovative materials and recycling of waste materials in order to compensate the lack of natural resources and to find alternative ways of conserving the environment. So, this paper presents the Results of an experimental investigation carried out to evaluate the strength properties of concrete in which fine aggregate was replaced with Copper Slag partially. The fine aggregates was replaced with percentages 0% (for the control mix), 20%, 40%, and 60% of Copper Slag by weight. Tests were performed for properties of fresh concrete and Hardened Concrete. Compressive strength was determined at 3days, 7 days,14days and 28 days. The results indicate that workability increases with increase in Copper Slag percentage. Test results indicate significant improvement in the strength properties of plain concrete by the inclusion of up to 40% Copper slag as replacement of fine aggregate and can be effectively used in structural concrete. Also as percentage of Copper Slag increases, the density of concrete increases. The workability of concrete increased with increase in percentage of copper slag. Toughness of Copper Slag is found to be more, which increases the compressive strength of concrete.</p>
