The optimal emulsifier (zeolite) for the preparation of bitumen pastes was selected, the main mineral of which is clinoptilolite, which has both an external and internal adsorption surface, provides both high hydrophilicity and low water demand of the zeolite, which makes it possible to obtain homogeneous viscous suspensions with a low water-solid ratio for bitumen pastes. The viscosity ranges of the water-mineral suspension necessary to obtain bituminous paste for emulsifiers of various nature and dispersion have been determined. It is shown that the zeolite-containing rock (ZSP) has the lowest water demand among the selected emulsifiers. The influence of the water-reducing effect of the plasticizer on the structure of bituminous pastes has been established.

One of the central tasks of the development of modern building materials science is the search, development and synthesis of new modifying components for cement composites that can provide traditional materials with new unique characteristics. The current environmental situation worldwide contributes to the fact that building materials must safe for nature, humans and animals. This article considers the possibility of using bismuth titanates as a fine additive to cement composites, which can provide traditional cement based materials with bactericidal properties, as well as the ability to self-cleaning due to the mineralization of organic and inorganic pollutants adsorbed on the surface of the material. During the experiment the additive was synthesized by citrate technology and introduced into the cement composition in the form of a stabilized suspension instead of mixing water. The optimal methods of processing to stabilize suspensions of bismuth titanates particles were studied, which is an important factor for achieving uniform particle distribution in the volume of the cement composite. There was an increase in compressive strength on the first and third days of hardening from 29 to 42 MPa (by 31, 38 and 45%) and from 53 to 70 MPa (by 28, 30 and 32%), respectively. At 28 days age the compressive strength increased from 83 to 97 MPa (by 2, 9 and 14%) compared with the control sample.

The paper deals with the process of production and properties of foam glass concrete – a composite material consisting of modified gypsum binder and granulated foam glass as an aggregate. Foam glass concrete has high strength, durability, environmental friendliness and low thermal conductivity, which makes it a promising material for wall structures. Optimal packing densities were obtained by using programs developed by the authors in the Python programming language to calculate the optimal diameters of three fractions of granular foam glass in an orthogonal or hexagonal packing model. The compressive and flexural strength and thermal conductivity coefficient were investigated on samples of different compositions. The value of the thermal conductivity coefficient of the foam glass concrete was reduced due to the air-entraining additive. In conclusion, the optimum composition of foam glass concrete was proposed taking into account all investigated parameters.

The solution to global environmental problems is to reduce the anthropogenic impact on the environment through the utilization of carbon dioxide emissions and the use of industrial waste to produce new materials and products. Technogenic wastes of the metallurgical industry are considered as raw materials for the production of building materials and products with the ability to bind gaseous CO₂. The analysis and selection of waste from metallurgical enterprises located in the Central and North-Western Federal Districts of the Russian Federation is carried out. The results of studies of environmental friendliness, chemical, material and phase-mineralogical compositions of technogenic metallurgy waste, their hydration activity and ability to bind carbon dioxide are presented. It is shown that the most promising raw materials for the production of building materials and products are steelmaking slags and nepheline sludge from the processing of alumina raw materials. The greatest ability to absorb and bind CO₂ is distinguished by nepheline sludge (up to 12% CO₂ by weight of sludge), steelmaking (converter and electric steelmaking) slags (up to 8.8 and 9.2% CO₂ by weight of slag, respectively). The compressive strength of the prototypes on these types of slags depends on the degree of their carbonation and reaches values of 100 MPa or more after 6 hours of forced carbonation. It is concluded that the material obtained from man-made metallurgical waste by carbonation hardening technology can be used as a matrix substance for various building materials and products.

Overburden and host rock deposits typically contain by-products. If selective mining is not applied, these aggregates are moved to dumps and deposited haphazardly. To preserve mineral resources, it is necessary to create man-made technogenic deposits. This article explores the prospects of comprehensive mineral resource development. Examples of creating technogenic mineral deposits in exhausted quarry spaces are provided. We emphasize the need for the enactment of laws that promote the formation of technogenic deposits.

Aerated concrete is a material widely used in Vietnam due to several advantages over heavy concrete. This article presents some results of experimental studies of the properties of aerated concrete produced using geopolymer binder from industrial waste generated in large quantities in Vietnam. The raw materials used included thermal power plant fly ash, blast furnace slag, ceramic powder, aluminum powder and an activating alkaline solution consisting of aqueous solutions of sodium hydroxide and sodium metasilicate. Testing of aerated concrete samples of the developed compositions was carried out in accordance with current Russian and Vietnamese standards. Experimental results confirmed the possibility of producing aerated concrete with a geopolymer binder based on large-tonnage technogenic waste, with an average dry density of less than 1600 kg/m³ and a compressive strength at the age of hardening of 28 days of 18.8–27.9 MPa. At the same time, aerated concrete containing 0.456 kg/m³ of aluminum powder and 50% wt. showed the greatest strength. blast furnace slag in the composition of the geopolymer binder, with a ratio of activating alkaline solution and active mineral additives equal to 0.4.

Within the framework of this paper, gypsum composites of different densities and strengths were obtained. The influence of different hydrophobizers on the softening coefficient of gypsum composite reinforced with plant filler was investigated. The crushed stem of Sosnovsky’s hogweed was used as a plant filler. The plant filler was pre-dried, treated with organosilicon hydrophobizers by irrigation method followed by powdering with gypsum binder. From the obtained mass, 4х4х16 cm specimens were fabricated. The pressing pressure was varied from 0.2 to 0.8 MPa. The density, flexural strength, compressive strength, and softening coefficient were determined for the obtained specimens. Increasing the pressing pressure increases the density and strength characteristics of the gypsum composite. Modification of the plant filler did not affect the density and strength of the composite but allowed 1.3–2.3 times to increase its water resistance.

The construction and reconstruction of buildings and structures on problematic engineering-geological and rugged territories with the presence of ravines, unstable slopes is an urgent task of modern geotechnical construction. It is further aggravated by the presence in the foundations of the designed objects of intermittent engineering-geological elements with reduced values of physical and mechanical characteristics. Often there are lenses, wedging out layers of soft soils with unstable physical and mechanical properties. The article considers the case of the construction of foundations using drill-injection piles ERT and monolithic reinforced concrete grillages for a mounted pressure pipeline with a diameter of 1020 mm.

Approaches to the production of electrically conductive concrete and the possibility of its application through the use of electrical properties in various industries are considered. The results of testing the compositions of fine-grained self-compacting concrete based on Portland cement CEM I 52.5 N, sand with a size modulus Mk=2.43 and polycarboxylate plasticizer for changes in electrical resistivity during hardening are presented. The increase in specific electrical conductivity was provided by the introduction of conductive components in various quantities, such as construction soot, carbon black K-354, graphite EUT-2. The positive effect of increasing the amount of the conductive component on the electrical resistivity for 28 days of normal hardening of the samples and on the ability to resistive heating by changing the surface temperature of the samples when passing a direct current with a voltage of 30 V. is shown.

The problem of thermal cracking in mass concrete structures still remains unsolved. There are many factors that influence the thermal regime in these concrete structures, the main ones being the type and content of cement in the concrete mixture, the thickness of the concrete layer, and the ambient temperature. However, the most important factor is the cause of the heat generated. Currently, there are a large number of standards and empirical formulas for determining the origin of a heat source using adiabatic equations. This paper provides a comparison of formulas for determining the adiabatic temperature in hardening concrete as the basis for determining the thermal regime in large-sized concrete structures.

The paper presents the results of determining the compressive strength of various compositions of Ultra-High Performance Fiber Reinforced concrete (UHPFRC) with fiber volume content from 1 to 3%. Four types of fibers were used: corrugated fiber of 15/0.3 mm and 22/0.3 mm, straight fiber of 13/0.3 mm and hooked-end fiber of 30/0.5 mm. It was found that corrugated and hooked-end fiber leads to an increase in compressive strength by 10–30 MPa when its content is increased from 1 to 3%. Straight fiber has no noticeable effect on the mechanical properties of UHPFRC. Empirical equations for predicting the compressive strength of UHPFRC depending on the strength of concrete matrix, geometric dimensions and content of dispersed reinforcement for compositions with corrugated and hooked-end fibers have been obtained. It is found that increasing the volume content of aggregate in the concrete matrix composition from 0.2 to 0.4 m³/m³ leads to an increase in the strength of UHPFRC. The strength of specimens with corrugated fiber increased by 5.3–13.3 MPa, with hooked-end fiber – by 14–19.3 MPa, with straight fiber – 5–7 MPa. It is also noted that the most intensive growth of mechanical characteristics due to the increase in the aggregate volume content in the composition is observed at a higher percentage of fiber volume fraction.
