Eco-efficiency evaluation of sustainable self-compacting concrete using magnesite mine waste AITranslate
Abstract AITranslate
Utilization potential of industrial by-products/wastes as construction material requires adequate workability, strength and other required properties as specified by standard codes of practice and certain sustainability criteria. Coal combustion byproduct (fly ash) and mine waste are a few of the abundantly available wastes that create a challenging task in their disposal with the current practice of dumping on-sites and landfilling. This study enumerates the suitability of utilizing magnesite mine wastes in self-compacting concrete (SCC) as binder and aggregate replacements by considering the evaluation factors such as fresh, hardened properties, life cycle assessment (LCA) and eco-efficiency. The results from the experimental investigation revealed that aggregate blended SCC performed well in terms of both fresh and mechanical properties, while cement blended mixtures exhibited satisfactory results. Additionally, fly ash and magnesite mine waste substantially reduced CO2 emissions and costs with added strength benefits. Eco-efficiency evaluation of mine waste blended SCC reported up to 75% higher efficiency than conventional SCC.
