Abstract: Due to rising population and consumption, resource depletion has emerged as a serious concern for governments throughout the world in recent times. The current trend towards resource conservation has prompted a number of potential solutions, none of which have been universally implemented. Sustainable manufacturing, responsible consumption, sustainable building, and many other initiatives have been integrated into traditional operations in recent years. The building industry is one of the most consequential for the growth and prosperity of any country. Therefore, these resource conservation-based issues in the building industry require attention. Sustainability in building is seen by academics as a catch-all phrase encompassing a number of different efforts, such as material optimisation and material replacement. As a crucial topic to investigate within the sustainable building context, material replacement is considered in this study under these methodologies. More and more research has concentrated on finding ways to turn trash into resources for various purposes in order to create efficient waste management systems and effective mechanisms for conserving resources. Concrete applications that include waste material are gaining popularity. The current research is limited, but certain of the waste elements, particularly mining waste, may be a superior substitute for traditional concrete components. To fill this need, this research introduced mining waste as a possible alternative to traditional concrete, particularly self-compacting concrete. In order to comprehend and evaluate the interdependencies and relationships among the gathered difficulties, the study incorporates numerical modelling. By incorporating mining waste into self-compacting concrete, the study's findings remove obstacles to sustainable building. This research took four distinct kinds of mining waste into account: bauxite, copper, stone rock, and steel. The effects of varying amounts of mining waste in geopolymer triple-blended self-compacting concrete were the subject of many experimental investigations. The results show that 4% copper residue outperforms the alternatives in all of these tests. It can be as much as 1.3 to 1.1 times more than regular concrete mix. Two tests, the water absorption test and the sorptivity test, were administered as part of the durability study. The alternatives that were being examined were compelled to participate in these tests. Two types of mining waste—4% copper residue and 3% bauxite residue—performed better than the other under both sets of tests. The addition of this mining waste improves dependability in both instances. Experimental analysis concluded with tribological testing, which included a battery of tests measuring things like corrosion potential, alkalinity, acidity, chloride ion penetration, and more. Compared to the other options tested, 4% copper residue performed better in all of the following experimental tests: acidity, chlorine penetration, corrosion potential, current density rate, and current passing value. Based on these results, the study concluded that 4% copper residue, when used as coarse aggregate replacement in triple blended geo polymer self-compacting concrete, improves the material's strength, durability, and surface tension. Additional mining waste and percentage blends can be included in future extensions of this study.
