SUMMARY:

The quest for clean energy production, particularly in wind power generation, has driven an increased demand in the metalworking industry employing the submerged arc technique. Unfortunately, this surge in production has also resulted in a rise in flux slag waste. Frequently, welding slag is improperly disposed of, causing environmental harm. Simultaneously, the construction industry has been striving to minimize its ecological footprint by innovating new materials for enhanced performance and incorporating waste from other industries to mitigate environmental damage. This research endeavors to investigate the integration of submerged arc welding flux slag into cementitious mortars, promoting sustainability and responsible management of industrial metalworking waste. By incorporating this slag into mortars instead of traditional aggregates, the need to extract natural resources from riverside areas is eliminated, contributing to resource conservation, and reducing environmental impact. The chemical composition of submerged arc welding flux slag, which remains inert when mixed with water, aggregates, and binders, makes it an ideal substitute for coarse sand in mortars and floor coverings. This substitution can yield a substantial economic benefit of approximately 85% when compared to conventional aggregates, constituting 20 to 25% of the total manufacturing cost of the mortar, simply by maintaining the same material proportions. Preliminary studies have shown that this integration has the potential to offer technical advantages, including increased mechanical resistance to compression, which, in some instances, may reduce the required cement dosage and subsequently lower production costs. This approach is in line with sustainable development policies, such as the sanitation framework, which advocates for responsible industrial waste management and the promotion of sustainability.
