The demand for the use of high-quality materials is growing day by day. When using building materials, it is necessary to take into account not only economic and social factors, but also aesthetic aspects. The materials applied to them to obtain high-standard construction complexes will also meet certain requirements. The article presents an overview of materials used in foreign construction works used in recent years, and internal construction repair works that are considered effective in our country. The importance of effective materials aimed at reducing labor costs and reducing the economic growth of the construction industry in the country is characterized. One of the most effective modern materials is dry building mixtures. Due to the rapid development of production and the expansion of the range of dry building mixes (DBM), the use of local raw materials in their composition is an urgent issue. Dry construction mix is a powdered product made on the basis of components such as cement, gypsum, polymer. By adjusting the ratio of modifier mixtures, you can intentionally change the properties of the mixture. The main elements in conventional dry mixes are gypsum, lime or cement. Therefore, the authors have proposed a method for obtaining a new dry construction mixture for carrying out internal construction repairs in the presence of chalk-ash-gypsum. According to the results of the research work, a method for obtaining a quick-drying and quick-drying dry construction mixture was proposed and technical indicators were determined.

Abstract. For the majority of Kazakhstan sewage treatment plants, the issues of modernization and construction of new blocks of wastewater treatment facilities are very relevant, the solution of which involves a comprehensive engineering and technological approach. This article analyzes the level of automation and disadvantages of the project of the second stage of sewage treatment plants (STP) of the State Enterprise "Astana SU Arnasy". The project of biological treatment on the aeration tanks of the second stage of (STP) does not provide for deep cleaning for biogenic pollutants, namely the internal recycling of activated sludge. The volume of the anoxic zone is 18%, which is not enough for the process of biological dephosphotation. Thus, in order to more effectively achieve high-quality cleaning indicators, it is necessary to provide for a denitrification zone of at least 30% of the total volume of the aeration tank. Analysis of the main causes of inefficient removal of phosphates at the stage of biological purification showed: insufficient concentration of biological oxygen consumption in incoming wastewater, absence of denitrification process, dephosphotation in the design of the second stage aerotanks and insufficient volume of the anaerobic zone, which is 18% of the volume of the aerotank. The problems of inefficiency of technological wastewater treatment from phosphates at (STP) in Astana are primarily related to design errors and the impossibility of effective operation of wastewater treatment facilities associated with insufficient automation. Thus, in order to increase the efficiency of the biological treatment facilities of the second stage, it is necessary to carry out a new calculation of the facilities taking into account the processes of nitri-denitrification and biological removal of phosphates, additionally equip with equipment to ensure internal recycling with the allocation of intermediate zones and in the process of retrofitting to provide greater automation to minimize manual labor.

All buildings, regardless of their use, must provide a controlled internal environment, protected from the changeable and uncontrolled external climate. The requirements for the internal environment depend on the intended use of the building, which naturally determines the requirements for enclosing structures. Thus, one of the simplest and most rational ways to save energy in the construction sector is to reduce heat losses through the enclosing structures of buildings and structures. One of the options for improving the energy efficiency of enclosing structures is the use of three-layer blocks with expanded polystyrene. The construction of external walls made of three-layer blocks of structural elements allows to increase technological efficiency by reducing labor intensity, construction time and cost of work, as well as to obtain a design that meets modern energy saving requirements and is energy efficient. The purpose of this article is to analyze the technology of construction of energy-efficient enclosing structures using three-layer blocks. The object of the article is the technology of construction of enclosing structures. The novelty of this research work lies in determining the current needs for the construction of energy-efficient enclosing structures, as well as in studying the technology for their construction from three-layer blocks.

The efficiency of operation of mining machinery products is determined not only by the quality of its manufacture, but also by the use of design schemes that allow maximum adaptation of mining equipment to complex and constantly changing technological working conditions. In particular, the use of various types of structures of a special type of transport equipment - plate conveyors depends on such parameters of mining enterprises as: distance and depth of delivery, angle of inclination of transport workings, etc. This type of conveyor is most widespread in the open-pit mining of minerals, in ore quarries and sections. With a continuous increase in the depth of quarries, the need to increase their productivity in terms of rock mass, the cyclical technology used in open-pit mining with road and rail transport led to a deterioration in technical and economic performance. The cost of mining increased as a result of the increase in the cost of using cyclical modes of transport. Operational experience has shown that for every 100 m of the pit depth, the costs of using vehicles with a lifting capacity of 30-40 tons increase by an average of 1.5 times. The use of railway transport in most deep quarries is excluded due to the impossibility of fitting rolling stock into the relatively small size of ore bodies and the parameters of the quarries. In this regard, the issues of developing technical solutions aimed at creating constructive schemes of plate conveyors that allow them to work effectively in the constantly changing technological conditions of modern quarries and sections are of undoubted relevance. The purpose of the work: development of a design scheme for a multi-drive plate conveyor with a frequency-controlled asynchronous electric drive

The results of the work of EcostroyNII-PV LLP on the processing of technogenic waste of energy and metallurgy of the Republic of Kazakhstan, Pavlodar region are presented. The use of waste in the manufacture of construction products is one of the most effective solutions to environmental problems in the region. The proposed technology for the production of construction products using ash and slag waste provides for innovative compositions of raw materials mixtures and provides an increase in operational characteristics and an increase in labor productivity in construction. The applied technology, in comparison with existing analogues, provides for the use of local waste (ash and slag waste from the burning of Ekibastuz coal, bauxite sludge of the Pavlodar aluminum plant, steelmaking slag). They differ in chemical and granulometric composition, as well as binding properties from other analogues and prototypes. In the production of construction products, a concrete mixture has been introduced and patented, including, %: slag-Portland cement - 14.32-17.00; sand - 18.74-25.52, crushed stone - 46.50-49.71, alumina sludge obtained during processing of Kazakhstan bauxite – 5-7; self–disintegrating slag of steelmaking production – 5-7; ash and slag waste of thermal power plants from burning Ekibastuz coals - 5-7. According to the test results, the average tensile strength of building products (paving slabs, curbstones, hollow bricks) is 3.2 – 3.8 MPa (strength class 2.5).

In this work, the magnetic properties of steel 13CrVwere studied in order to be able to conduct a non-destructive determination of the values of mechanical properties. The analysis of the existing methods of non-destructive testing of mechanical properties is carried out and the prospects of using a magnetic method for determining mechanical properties instead of the standard destructive one - tensile testing are substantiated, and the advantages of the magnetic method of determination over other non-destructive methods, such as thermal and mechanical, which use the measurement of thermal conductivity and hardness by Brinell, respectively. The effect of a change in strength properties on the value of magnetic indices was determined, for which purpose quenching was carried out on steel samples followed by tempering at temperatures of 500, 550, 600, 650 and 700 С. The decrease in the coercive force and the increase in the residual magnetic induction and maximum magnetic permeability during tempering of steel from 500 to 650 Сare substantiated, and the reason for their change in the opposite direction is also revealed. Recommendations are given on the choice of magnetic characteristics for nondestructive testing of their structural state. The nonmonotonicity of changes in the values of magnetic properties is revealed and the extrema of the curves of the diagrams associated with the change in the structure of tempered steel are substantiated.

Cementation extraction of metals from solutions is widely used in hydrometallurgy. It is known that the cementation process is significantly influenced by the layer (precipitate) of the cemented metal crystallizing on the surface of the cementator metal. The compact layer isolates the sur-face of the metal-cement from the solution, and the cementation reaction slows down or stops altogether. On the contrary, powdered (dispersed) sediment not only does not slow down cementation, but in some cases even increases the speed of the process, which is facilitated by the devel-oped surface of the cathode sites on which the ions of the cemented metal are restored. Since aluminum is a less expensive metal than zinc, and tin sulfate is a by-product of electrolytic refining of some metals, it is of practical inter-est to investigate in more detail the process of cementation reduction of tin from SnSO4 solution. In this paper, it has been experimentally established that in order to implement the process of cementation extraction of tin in dispersed form from SnSO4 solutions, the cementing metal aluminum must be activated with chlorine ions. The results of polarization measurements of electrode processes of the Al-Sn contact electroplating are consistent with the re-sults of the planned experiments on obtaining tin powder of tin cementa-tion with aluminum from SnSO4 solutions, taking into account the influ-ence of the competing process of water separation.
