SUSTAINABILITY ANALYSIS OF COPPER SLAG AND REPLACEMENT FOR CONCRETE
Abstract
Chile is one of the largest copper producers in the world, which implies a significant generation of waste, particularly copper slag (CS). On the other hand, the high demand for concrete mixes generates a high consumption of natural aggregates as sand. However, specialized literature indicates that the fine aggregate can be partially replaced by CS keeping (or improving) the concrete properties. Then, this paper presents a sustainability analysis of the partial replacement of fine aggregate of concrete by CS. The magnitude of the benefits that would be obtained from recycling at an environmental, economic, and social level will be directly associated with the legislation and will condition the responsibility of the producer regarding their waste. In addition, aggregate extraction is reduced having an extra positive effect in the natural capital. Finally, there are social benefits associated m
