Today, processing low-grade raw materials draws widespread interest. This aligns with the federal project “Circular Economy”, which explores alternative raw material sources – overburden rocks and naturally occurring soils of similar composition – and practical processing technologies to replace traditional materials like crushed stone and sand. Based on the raw material characteristics, engineers develop soil-concrete formulations with a complex mineral binder to meet required physical-mechanical and water-physical properties. To study how the raw materials interact with binder components during composite synthesis, researchers apply a set of physicochemical analytical methods using high-precision equipment. They evaluate the raw material properties according to GOST 25100-2020 and test the synthesized composites per GOST R 70452-2022. Findings show that these procedures produce effective road-construction composites for road bases, achieving strength grades M40-M75 and frost resistance grades F10-F15. The proposed approaches support scaling the solution, including recycling mining waste – mainly clayey overburden rocks – into usable construction materials.

Currently, the use of special dust-suppressing reagents is promising to reduce the level of dust in the vicinity and on the territories of pits, mining and processing plants and other facilities with a high content of fine dust. The analysis of ways to reduce the dust-forming ability of inorganic dispersions with a high degree of dusting is carried out. Due to the lack of regulatory and technical documentation devoted to the standardization of quality control methods for dust-suppressing compounds, it becomes necessary to analyze existing parameters and methods for their determination in order to develop mandatory methods for controlling the properties of dust-suppressing compounds, films formed by them and consolidated systems. The study is devoted to substantiating the necessary methods for assessing the dust-forming ability of inorganic dispersions after treatment with various dust suppressants and evaluating their effectiveness. The parameters are considered and methods for quantifying the determination of the quality of the consolidated layer of dust samples using different dust-suppressing compositions are described. As a result of the analysis of the set of parameter values, it was found that the most resistant to the effects of negative factors due to the formation of a denser and more durable polymer matrix mesh are dusting surface samples treated with an emulsion of alkyd glypthalic resin on a water basis with a high agglomerating effect on particles of inorganic dispersion and the formation of a consolidated layer with a wetting angle of 92.5° and a compressive strength 0.56 MPa.
