Industrial waste in concrete mixtures for construction of underground structures and minerals extraction

An increase in population leads to an increase in the density of inhabitants in megacities and leads to an increase in consumed raw materials. The paper presents the description of the problems that arise for builders when building density increases and for producers of raw materials that arise when raw material is intensified. The analysis of the impact of construction and mining waste on the environment was carried out. Compositions of concrete mixes and methods of their preparation are offered to improve the quality and safety of life in megacities, as well as the safety of mining operations along with reducing the human impact on the ecosystem. Aspects of preparation of concrete mixes and questions of improvement of its quality by activation of components are revealed. The possibility of activation of construction and mining waste used as an inert aggregate in considered. The possibility of realization of non-waste production is considered. © Published under licence by IOP Publishing Ltd.
