“…General technical conditions" [14,19] sludge after appropriate preliminary processing can be used for the production of construction sands and as alumina aggregates for cellular concrete in the production of construction products, such as polystyrene concrete blocks. According to the granulometric composition (tables 1, 2), construction sand can be obtained from sludge using hydraulic processing technologies that can technologically and economically remove dusty and fine impurities [20][21][22][23][24]. Given the significant number of such inclusions, it is rational to use the technology of multi-stage gravity classification, which consists in the alternate and sequential use of vertical and horizontal accelerated flows of the carrier flow for gravitational separation of solid particles by size and density.…”

The aim of the study is to substantiate the parameters of technology and equipment for the manufacture of building products using alumina sludge from stone processing as an alumina aggregate. The standard methods of setting up an experiment for laboratory washing of granular sludge from stone processing and studying its physical and mechanical characteristics, manufacturing laboratory samples of polystyrene concrete blocks with further study of their strength characteristics were used. The physical and mechanical characteristics of granular man-made material - sludge waste from the stone processing industry - were experimentally determined. The possibility of using man-made sludge in the manufacture of polystyrene concrete blocks was substantiated by its particle size distribution and mineralogical composition. Average samples of granular material were deslagged using the TurboWash unit. The particle size distribution of the material after washing was analysed. According to the standard technology, recipe and raw materials for D300 polystyrene concrete, polystyrene concrete blocks of standard sizes of three grades were produced. Primary sludge without preliminary processing, sand and dusty loess obtained from the processing of primary sludge were used as an aggregate. The numerical values of the axial compression resistance for the studied grades of polystyrene concrete blocks were determined.

The publication examines the impact of seismic waves from the mass detonation of the gravel section of the quarry on solid areas suitable for extracting dimension stone in the conditions of the Leznikivsky quarry (Ukraine). Seismic measurements in the quarry were analyzed. Based on the obtained data, seismic-safe zones for mass detonations of gravel sections were identified, and the maximum allowable charges of explosive materials in a single borehole were calculated.
