Abstract

This article explores the potential of using concrete made from a cement mixture with blast furnace slag additives for construction in the Russian Arctic to promote sustainable development in the region. Utilizing industrial waste as recycled raw materials aligns with the principles of green and circular economy. Recent observations have shown local symbiotic effects, such as reduced material costs and mitigated environmental impacts. Replacing clinkers with mineral additives during cement production has been noted to reduce the carbon intensity of the final product. Further reductions in greenhouse gas and pollutant emissions can be achieved due to the long-term preservation of thermal insulating properties and the relatively slow degradation of the structure. Comparative laboratory tests were conducted on concrete samples made from cement with 15% (by weight) mineral slag and cement without additives. The dynamic indicators of density and hardness of the cement samples were assessed under simulated natural conditions. The inclusion of mineral additives alters the chemical reactions during the hardening of the concrete in contact with air and water, without prolonging the process, and increases hardness, even with frequent cycles of freezing/thawing and hydration/dehydration, thereby extending the service life of the structures. The obtained data were extrapolated to evaluate the environmental and economic indicators of construction and maintenance; accessibility, suitability, durability, and resource efficiency were identified as the key characteristics. The study concludes that using cement with mineral additives from blast furnace slag in the Arctic is feasible.
