The possibility of producing cement clinker using low-energy, resource-saving technologies is studied. The composition of industrial waste for low-energy-intensive production of Portland cement clinker at factories in Southern Kazakhstan is analyzed. The possibility of replacing the deficient iron-containing corrective additive with “Waelz clinker for zinc ores” is shown. “Waeltz clinker from zinc ores” as part of the raw material charge performs several tasks: it is a ferrous corrective additive, works as a mineralizer for clinker formation processes, introduces coal into the charge and allows one to reduce the consumption of natural fuel. The processes of burning raw mixtures, wholly or partially consisting of industrial waste, are completed at 1350 °C. This reduces the consumption of main burner fuel for clinker burning and reduces CO₂ emissions into the atmosphere. High-quality cement clinker is obtained based on raw material mixtures with Waeltz clinker from zinc ores from the Achisai Metallurgical Plant, phosphorus slag, coal mining waste from Lenger mines and sodium fluoride. The phase composition and microstructure of low-energy clinkers are revealed. Involving industrial waste in raw material circulation will reduce environmental pollution and improve the environment.

The concept of the sustainable development of the world economy is currently aimed at achieving carbon neutrality, and this is due to the global warming of the planet. Energy and construction make a significant contribution to the release of carbon emissions into the environment and atmosphere. According to statistics, simply burning one ton of Portland cement clinker provokes the release of at least half a ton of carbon dioxide. In this study, the prepared samples were subjected to electron diffraction studies, as well as the X-ray phase analysis of the zone (XRF) using an ARLX’TRA diffractometer. Studies of macro- and microstructures were carried out using a Quanta 3D 200i scanning microscope. The obtained spectra were processed using EDAX TEAM software. The study of the microstructure of the samples showed that the bulk of the heterogeneous systems consisted of volumetric aggregates and intergrowths, i.e., small accumulations on their surfaces with pronounced cleavage, features of the microstructure indicating mineral formation processes. Therefore, the development of low-carbon construction models will make it possible to make a contribution and open an effective path to the implementation of climate policy through the rational use of natural resources and the involvement of industrial waste and nature-like technologies in the production process. In this regard, one of the options for solving the identified problems is to revise existing technologies and develop low-carbon, low-clinker binders using industrial waste and substandard raw materials.

This article discusses the current problem of industrial waste disposal and its use in the production of building materials, which corresponds to the global concept of sustainable development. Attention is mainly paid to the development of a gruntosilicate composite (concrete) based on a mineral slag binder using drilling sludge from the mining industry, ashes from thermal power plants and electrothermophosphoric slag. Physico-chemical studies of man-made raw materials have been carried out, including analysis of chemical and mineralogical composition, granulometric characteristics, radiation safety and other parameters. It has been established that drilling mud, thermal power plant ash and electrothermophosphoric slag meet the requirements for use in building materials and belong to non-hazardous waste. The optimal ratios of the components in the composition of gruntosilicate concrete have been experimentally determined. The highest compressive strength (3.0–3.5 MPa) is achieved with a drilling mud content of 15–23% and a mineral slag binder of 10–20%. It is shown that the introduction of these wastes improves the structure of the material, reduces shrinkage deformations and ensures compliance with the requirements of road surfaces of the II–III classes. The use of industrial waste in construction will reduce the cost of raw materials by approximately 10–30%, reduce the environmental burden and solve the problem of waste disposal. The results of the study demonstrate the prospects of creating a waste-processing industry capable of processing up to 40% of industrial waste into building materials.

A Portland cement is a basic initial component for concrete and reinforced concrete manufacture, which defines their technical-economic and operational properties. One of a perspective ways of increase in the efficiency of cement production without essential change of its technology is inclusion of various mineral additives influencing on a structure and properties of a cement stone. As power inputs make the most part of the costs necessary for cement manufacture, the cement industry is interested in decrease in fuel and electric power expenditures per 1 tonne of cement. To reach the decrease in power inputs and at the same time to raise the environmental safety of cement production the cement industry is recently focused on increase in output of composite cements. Composite cements not only promote optimization of the production in terms of ecology, but also can provide such technical advantages as lower hydration heat, higher chemical resistance and placeability.

Kazakhstan is embarking on a fresh approach to managing waste, aiming to recycle and repurpose solid household waste while integrating innovative, eco-friendly technologies for its treatment and disposal. The main goal is to reduce the amount of waste sent to landfills and instead convert it into more stable forms, lessening its harmful impact on the environment. This effort requires a comprehensive strategy, especially as existing landfills still need to be managed and rehabilitated when they reach capacity. It is essential to use municipal solid waste as a resource for producing various goods, which not only helps in landfill management but also aligns with principles of sustainability. This approach aligns with circular economic principles and helps to reduce the technological impact of landfills on the surrounding environment. The main types of waste in the Aktas landfill were identified as a result of this research: it is glass, of which only 3% is recycled. In our results, the setup allowed for the extraction of valuable components from the fine fraction, which can then be recycled. This enriches the organic material ready for composting (organo-mineral raw material mixture) with food waste.

The need for high quality of building products and structures determines the urgency of creating new ways to control the processes of forming the internal structure of modern composite building materials. This article discusses some aspects and problems on designing high-powder composites based on the law of similarity. The results showed that the determination of the compositions of these materisls and high adhesion property to each other and a low deformation characteristic. The results demonstrated that this less deformation characteristics is due to the similarity of the thermai expansion coefficients of the concrete components.
