Currently, the amount of man-made waste worldwide is steadily increasing. It is, therefore, necessary to constantly look for effective ways of utilization and recycling. It is also necessary to reduce the use of non-renewable resources and reduce the impact on the environment. The use of coal industry waste is currently quite insignificant, amounting to some 10% of the total volume. The work aimed to study the properties of raw materials and study the processes of structure formation during the forming, drying, and firing of composite ceramic produced using overburden rock and additives. The work’s relevance lies in the need to solve environmental, economic, and technological problems related to the utilization of coal mining waste. Experiments of the past prove the possibility of using the waste coal industry as additives in the production of building materials. The article presents the results of studies of the chemical, mineralogical, and granulometric composition of overburden rock in coal mining. Peculiarities of structure formation during the forming, drying, and firing of ceramic composites based on optimal fractional compositions from coal-mine overburden were revealed. Organic and chemical additives were used for the correction of technological properties and improvement of the quality of finished composite products. The physical and mechanical indices of the obtained composite ceramic samples were determined, the analysis of which revealed that the use of highly mineralized carbonaceous rocks as solid additives provided a 2–2.5-fold increase in the strength of the product, 5.6% reduction in water absorption, and an increase in the product frost resistance by 20–25 cycles. The aluminum oxychloride influence on the physical and mechanical indices of the obtained composite articles was reflected in a reduction in their water absorption from 8.2 to 7.0%, a 10–12% increase in strength in compression, and an increase in freeze–thaw resistance by 30–35 cycles. Research results proved that the composition and properties of coal-mine overburden rock are close to those of conventional clays. With special technological preparation, they can be used for the production of composite ceramic products. This will significantly reduce the cost of bricks, to make up for the shortage of high-grade clay raw materials and improve the environmental situation. Nevertheless, further research into the use of coal-mine overburdens in the composite ceramic material technology is warranted.

The purpose of the study is to create a macromodel of interfacial transition layer in ceramic matrix composites. Chemical and mineralogical compositions were investigated by means of X-ray fluorescence analysis and X-ray diffractometry, ceramic and technological properties of raw materials were defined using standard test methods for argillaceous raw materials. Phase composition and structure of ceramic specimens were studied using a complex of modern physico-chemical analysis methods. The layer-by-layer model of shell-core transition in ceramic matrix material was suggested. Boundary conditions for obtaining specimens were defined in terms of number of layers, thickness of such layers and pitch of core-to-shell material ratio. Forced air supply was organized while burning for directed heat and mass transfer inside the specimens. Mineral composition of layers was defined for ceramic specimens with the core of iron ore waste and the shell of clay. The study enabled to determine dependences between qualitative and semi-quantitative variation of new mineral formations content in transitional layers of a composite, which is the evidence of interaction between the core and the shell products while burning a ceramic matrix material.

The study results of the chemical, particle size, and mineral compositions of the raw materials of ceramic samples (coal waste and clay) are presented. A model of the transition layer between the shell and the core of the ceramic matrix composite is provided. The technique for preparing multilayer ceramic samples imitating the phase boundary of a ceramic material of a matrix structure is described. The differentiated studies of the phase composition and microstructure of multilayer ceramic samples are presented. The interaction of the products of the core and the shell in the transition layer in ceramic materials of the matrix structure during firing is established.

It have been presented the study results of the ash content and mineral composition of the waste from the enrichment of carbonaceous argillites by thermal and X-ray phase analyzes. It has been shown using of coal waste as the main raw material for the production of building ceramics. Problems are noted in assessing and choosing the name of the color of ceramic bricks based on industrial wastes. A method for determining and adjusting color using a synthesized digital palette is described. The proposed use of search engines and digital color databases to determine the names of the colors of building ceramic materials.

The relevance of the modernism era cultural heritage objects preservation for the traditions continuity and generations communication , especially in the time of mass communications digitalization. The example of the first Kuzbass sound cinema shows the history of its formation, change and evolution, which is inextricably linked with the history of Soviet and post-Soviet Russia in peacetime, wartime and global upheavals. Based on the results of the historical data analysis, six stages of the cinema development were identified: formation; pre-war and war years; postwar architectural modernism; socialistic development; perestroika of the 1990s; modern cinema restoration. The functional transformations of the modernism era object at the present reconstruction stage from the cinema to the puppet theater, related to the functionality expansion, are given. Restored fragments of the unique stained-glass cinema windows, which are a piece of decorative art, are considered. The urban value of the cinema “Kommunar,” which has retained its significance in the historical center of the city of Novokuznetsk as the modernism era cultural heritage object, is indicated.
