As a result of tests carried out under industrial conditions, the influence of using modifying waste materials in the production process of silicate brick on its main performance properties was evaluated. The studies were conducted at an operating silicate brick manufacturing plant, where experimental and industrial trials were performed on full-size brick specimens produced under factory conditions. Ground waste glass and expanded clay dust were introduced into the silicate mass as modifying additives. The research results showed that, while maintaining the normative levels of compressive strength and frost resistance, the modified silicate brick exhibits reduced average density and thermal conductivity coefficient. In addition, the use of expanded clay dust made it possible to obtain bricks with a natural brown shade without the use of special mineral pigments. The obtained results confirm that the modified silicate brick is an energy-efficient, reliable in service, and economically viable wall construction material.

Тазартпа қазбасының табаны мен төбесіндегі бұзылыс аймағының қалыптасу динамикасын талдау нәтижесінде байқаймыз. 322-Д6-3-З лавасының бұзылу қадамдарына болжам жасалды. №22585 мен 22576 барлау ұңғымалары бойынша мәліметтер алынды. Бөлшектеу-жинау кенүңгірінің кендіңгегінен 56-59 м қашықтықта бірінші бұзылыс орын алғандығын шақтының маркшейдерлік қызметі бақылаған кезде табанның жиырылуы әсерінен 2018 жылы тазартпа кенжарының центрінде метанның көп бөлінуінің әсерінен газдинамикалық құбылыс болды. Лавада өте қатты газбөліну байқалынып, тазартпа кенжарында 4000 тоннадан 3000 тоннаға дейін төмендетілді, бұл дегеніміз газдинамикалық құбылыстың негізгі төбенің бұ-зылу қадамдарымен өзара байланысын көрсетеді As a result of the analysis of the dynamics of the formation of the destruction zone, the roof and soil of the chamber. Lava 322-D6-3-Z destruction steps were assumed. The data were obtained for exploration wells No. 22585 and 22576. In 2018, a gas-dynamic phenomenon occurred due to the release of a large amount of methane in the center of the working face due to heaving of the soil, when the first disturbance occurred at a distance of 56-59 m from the rear of the assembly chamber. An extremely strong gas degassing was observed in the longwall, which at the working face decreased from 4000 to 3000 tons, which indicates the interaction of the gas-dynamic phenomenon with the main stages of roof collapse В результате анализа динамики формирования зоны разрушения кровли и почвы камеры были предположены шаги разрушения лавы 322-Д6-3-З. Данные получены по разведочным скважинам №22585 и 22576. В 2018 году произошло газодинамическое явление из-за выброса большого количества метана в центре очистного забоя из-за пучения почвы, когда первое нарушение произошло на расстоянии 56-59 м от целика монтажной камеры. В лаве наблюдалась чрезвычайно сильная дегазация газа, которая на очистной забой уменьшилась с 4000 до 3000 тонн, что указывает на взаимодействие газодинамического явления с основными стадиями обрушения кровли

The aim of this study is to analyze the architectural identity of historic cities of Kazakhstan in the context of the current urban changes. The purpose of the research is to give the theoretical knowledge about the nature of architectural identity, factors affecting the creation of identity and to reveal the problems of cities in the conditions of globalization. Scientific interest of the study is related to the possibility of generalization of theoretical approaches and the analysis of the relations between cultural memory, urban morphology and the current architectural practice. The methodology used is comparative-historical analysis, morphological approach, examination of the contextual characteristics of the urban environment and critical examination of scientific literature. The results show how standardization of architectural solutions, commercialization of historic city centers and the absence of effective regulatory solutions can be responsible for the loss of local identity. The study concludes that a change in design principles in favor of contextual design is required, along with a promotion of the concepts of critical regionalism and the need to establish architectural codes that take into account local cultural and historical details. The research's significance is the creation of a theoretical basis for the preservation of the identity of historic cities. Its practical significance is related to the possible use of the proposed approaches in the development of urban planning policies and regulatory frameworks for historic areas. Furthermore, it highlights the need for the integration of cultural heritage in the modern concept of architecture. The recommendations proposed can be used as a foundation for sustainable urban development strategies.

The main regularities of changes in the physico-mechanical properties of ceramic masses in the range of firing temperatures of 850 -1150 oC in the composition of the flask of the Taskalinsky deposit - clay of the Pogodaevsky deposit – ash-entrainment of the Ekibastuzky GRES have been established. It is established that with increasing temperatures, the indicators of average density and increased compressive strength increase.
