during the implementation of the program to restore the housing stock of the Chechen Republic, as well as during the planned demolition of dilapidated housing, significant volumes of technogenic raw materials were generated, in particular, large volumes of brick and concrete scrap. Enterprises for the production of building materials and products also produce significant volumes of production defects, which accumulate over the years at landfills. Ceramic broken brick and broken brick dropouts are used to fill the roadbed, and the main part still goes to the dump and landfill, which is also an environmental problem. One of the promising ways to use dropouts and broken brick itself is to use them as secondary aggregates in concrete and mortars. This article discusses the issues of improving the quality of ceramic concrete mixtures, choosing the optimal composition and technology for mixing concrete mixtures using dust fractions of dropouts for crushing ceramic brick bricks

Industrial transition to a totally new level of resources and energy saving necessitates improving the technical level of building materials manufacturing, growing their raw materials base, the assortment, enhancing the quality of manufactured products, cutting their cost price. It requires, first of all, carrying out more detailed research in properties of clay and clay loams, and selecting optimal additives for pottery works. Such disadvantages of clays as burning sensitivity, low compression resistance and flexural strength in a burnt state, low frost resistance cause the impossibility of their application without corrective additives. It is quite difficult to find an additive which can solve all the technological problems mentioned above. This paper provides the development of mixture "clay – electro-melting slag" for ceramic brick, moreover, addition of a steel-smelting slag in the fusion mixture results in the change in mixing water content of ceramic masses, strength and coloration of ceramic samples.

the use of technogenic raw materials in the production of building composites is an urgent direction in the technology of production of building materials in view of its economic efficiency, environmental effect and wide possibilities of their application. Recently, the issues of environmental safety in the production of building materials, the possibility of their processing and disposal have come to the fore. All this is dictated by the need for energy and resource conservation, the massive depletion of natural reserves and the progres-sive pollution of the environment due to anthropogenic activities. Construction composites provide ample opportunities for recycling of secondary raw materials, as their structure allows them to be used not only as a filler, but also in some cases as additives for regulating certain properties. More studied and widely used are ash and slag mixtures on the basis of which various organomineral additives are developed. So, on the territory of the Chechen Republic there are dumps of ash and slag mixtures, which, according to their chem-ical and mineralogical composition, are suitable for the design of organomineral additives and fillers in con-struction concretes and solutions. Building solutions are widely used for interior and exterior finishing works during the construction of construction projects in the Chechen Republic, which is characterized by high humidity in the winter, which provokes deformations of the plaster layer on facades. In this article, the de-velopment of an organomineral additive based on an ash-slag mixture is considered to improve the quality of mortar mixtures resistant to such conditions.

Biomass Fly Ash

The generation of energy for the needs of the population is currently a problem. In consideration of that, the biomass combustion process has started to be implemented as a new source of energy. The dynamic increase in the use of biomass for energy generation also resulted in the formation of waste in the form of fly ash. This paper presents an efficient way to manage this troublesome material in the polymer–cement composites (PCC), which have investigated to a lesser extent. The research outlined in this article consists of the characterization of biomass fly ash (BFA) as well as PCC containing this waste. The characteristics of PCC with BFA after 3, 7, 14, and 28 days of curing were analyzed. Our main findings are that biomass fly ash is suitable as a mineral additive in polymer–cement composites. The most interesting result is that the addition of biomass fly ash did not affect the rheological properties of the polymer–cement mortars, but it especially influenced its compressive strength. Most importantly, our findings can help prevent this byproduct from being placed in landfills, prevent the mining of new raw materials, and promote the manufacture of durable building materials.

The use of nanotechnogenic petrochemical raw materials-spent IM-2201 catalyst containing more than 70 % Al2O3, and as a clay binder-lowmelting clay from the Ilek Deposit in the Aktobe region allows you to get a ceramic brick that corresponds to the M150 brand. It is possible to build load-bearing walls of the lower floors of high-rise buildings (more than 10 floors) from M150 ceramic bricks. Innovative proposals for the use of waste from production and spent catalyst in the production of ceramic high-strength earthquake-resistant bricks with increased strength and frost resistance have been developed. The absolute advantage of using multi-tonnage waste and spent catalyst IM-2201 is to relieve the environmental situation.

Abstract Today, the waste of the mining industry is more than 8 billion tons. Analysis of the literature data showed that most of the man-made waste that is generated as a result of the development of mineral deposits is suitable for use in many industries, in particular, in the production of building materials. The use of technogenic raw materials allows us to solve the following tasks: Environmental aspect - reducing the number of dumps and reducing their volumes. And this, in turn, improves the ecology of regions and territories. 2. Economic aspect - reducing the cost of construction products through the use of almost free raw materials, the release of more competitive products. Of course, it is necessary to provide that part of the costs will be spent on additional processing, revision, activation, modification of this technogenic raw material component. But today we have to think about how to clear the territory of substandard “waste rock” and use it to reduce the production and consumption of natural raw materials. A similar process can create waste-free production.

Materials, products and systems used as finishing of external surfaces and/or interior rooms when erecting or reconstructing buildings and structures should: protect the person in the room finished with these materials from the pathogenic effects of materials, products and building systems; if possible, do not exert pathological physiological and/or activity loads on people carrying out production or life activities in rooms finished with these materials and/or equipped with products and systems. As a result of the research, it was found that the source of 80% of the chemicals found in the air environment of the apartments is used construction and finishing materials. Currently, the quality of raw materials for building materials and the building materials and structures themselves are determined by GOST and Technical Specifications. A civil engineer is required to correctly select a material, product, or structure that has sufficient strength, reliability, and durability for specific conditions. Safe in themselves, finishing materials, products, and systems in the composition can acquire and demonstrate new properties. Therefore, the study of this problem is an urgent task of the near future and one of the directions of construction anthropotechnology, in particular, when implementing high-rise construction projects.
