“…В последние десятилетия отдельные исследования были направлены на расширение потенциала использования пород крупных и имевших историю промышленной эксплуатации месторождений силицитов -Утесайского и Таскалинского -в отраслях, преимущественно связанных с разработкой строительных [9][10][11], конструкционных и отделочных материалов [12], для очистки воды [13], которые базировались на ранее сформированных рекомендациях к использованию этого сырья. В Республике Казахстан перспективы использования кремниевых пород палеогена связывают именно с развитием технологий пеностекла, как по причине потенциальной востребованности подобных материалов на местном рынке, так и в связи с тем, что силикато-и стеклообразование может протекать при температурах, близких к области вспенивания пеностекла, что облегчает технологическую реализацию таких проектов.…”

Diatomites and opoka from Western Kazakhstan deposits: lithogeochemistry, structural and textural parameters, potential of use. Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 7, рр. 187-201. In Rus. The relevance. In recent decades, individual studies in the Republic of Kazakhstan have been aimed at expanding the potential of using rocks of large and industrial exploitation of silicite deposits for revising their physicochemical, mineralogical parameters, and assessing the prospects for expanding their use in new industries and technologies in the construction and technical industries, materials science based on deep chemical processing of mineral raw materials. The article presents new data on the chemical-mineralogical and structural parameters of diatomites from the Utesai deposit and opoka from the Taskala deposit of the Republic of Kazakhstan. The main aim: comprehensive analysis of the chemical-mineral composition and structural and textural features of rocks from two largest deposits of silicon raw materials in the Western part of Kazakhstan – the Utesai diatomite deposit and the Taskala opoka deposit. Objects: diatomites of the Utesai deposit and opoka of the Taskala deposits in the western part of the Republic of Kazakhstan. Methods: field research, lithological and petrographic analysis of thin sections, X-ray diffraction analysis, differential thermal analysis, scanning electron microscopy, X-ray fluorescence analysis. Results. The studied diatomites and opoka are characterized by a high degree of homogeneity; they are represented by typical phases for silicic rocks of the region – opal-CT, clay minerals with an admixture of quartz and feldspars. From the mineralogical point of view, the most obvious difference between the studied diatomites and the Trans-Urals is the significant content of kaolinite – over 10 %, while in the diatomites of the Trans-Urals, the main clay component is smectite and mixed-layer illite-smectite formations. The rocks under consideration are clayey diatomites and clayey flasks, the total content of basic oxides allows us to characterize raw materials as medium quality, most suitable for the production of foam glass materials, and, in particular, glass fiber, in the production of which alumina is an important functional component. At the same time, the significant content of clay and other impurities does not allow us to recommend such raw materials for the production of filter and sorbing materials.

On the basis of various discourses (lexicographic, dialectal language, associative, artistic, advertising), we represent a research fragment dedicated to the description of colour perception and obvious chicory, the purpose of which is to create the fullest possible version of the color concept sphere of the floristic space of the language. The main results of the research are: 1) the quantitative and qualitative composition of colour terms that are significant in the presence of descriptions of chicory; 2) a dominant colour registry representing the colour standard for plant detection; 3) a list of different colour definitions associated with the area of the individual author's picture of the world; 4) functional of colouristic descriptions of chicory, represented by a spectrum of functions: from ontological to chronotopic and prototypical; 5) description of the current proposal for the production of acceptable variations in the combination of the meanings of colour terms based on the colouristic description of chicory. The theoretical basis was research in the field of cognitive linguistics, linguistics of colour; methodological – a set of methods and techniques, including the descriptive-analytical method, contextual, method of directed associative experiment, quantitative; continuous sampling technique. Obtaining results, visualization of the processes of conceptualization and categorization of reality in language, use as a research activity in research of various aspects of the language worldview, colour worldview, and in the educational and methodical work of the language in the preparation of cognitive linguistics, linguistics colour, copywriting, as well as in lexicographic practice and the practice of teaching a foreign language.

In this article, a physical and mathematical model of the unsteady process of heat and mass transfer in a flat reinforced concrete structure during its heat treatment by solar energy is proposed and considered. Monolithic concreting in the conditions of a construction site is currently widespread in the construction industry. The subject of the article is to consider the issues of heat treatment of concrete and acceleration of its hardening processes using solar energy. Analytical expressions have been obtained that simulate the process at any stage of it, which makes it possible to actively intervene and adjust the external parameters of the environment to create rational and comfortable conditions for concrete strength growth.
