Optimizing Concrete Strength and Sustainability: Quarry Dust and Copper Slag Powder Additives

Abstract

This research investigates the potential of quarry dust and copper slag powder additives to enhance the strength and performance of concrete. Compressive strength tests were conducted on mortar cubes at 7 and 28 days to evaluate the effects of these additives. The results indicate significant improvements in compressive strength over time, with Mix A4 achieving a remarkable 43.42% increase in strength at 28 days. Other mixes also demonstrated substantial strength gains, highlighting the effectiveness of quarry dust and copper slag powder additives in promoting both early and long-term strength development. These findings contribute to the advancement of sustainable and high-performance concrete materials, offering insights into their practical application in construction projects.
