“…Mixing should provide optimum conditions for the physical and chemical processes involved in the formation of the technological properties of the concrete mixture and its physical and mechanical properties during hardening. If the mixing time is insufficient, the homogeneity of concrete deteriorates, the coefficient of variation increases, and strength decreases [33]. Increasing the mixing time of the concrete mixture can lead to its segregation.…”

The addition of fly ash from thermal power plants (TPP) and chemical additives, such as polycondensation products of acetone and formaldehyde, is an effective and economical method for increasing the strength and durability of building materials, in particular concrete. Fly ash added to the concrete and mortars at 10%–15% does not reduce their technical properties, while polycondensation products of acetone and formaldehyde plasticize and accelerate the hardening process of concrete. The study aims to substantiate the possibility of obtaining concrete on dense aggregates with a high content of fly ash through the use of polycondensation products of acetone and formaldehyde as additives, which are highly soluble in water and polyfunctional. The strength indicators were determined using standard methods. The study has shown quantitative changes in the properties of the fly ash-concrete mixture, improvement of its physical and technical characteristics, and durability of the fly ash concrete with the addition of polycondensation products of acetone and formaldehyde. In the present study, the authors determine the effect of fly ash addition on the properties of a concrete mixture, as well as the maximum possible content of fly ash that can be added to concrete to maximize certain properties required of the mixture; additionally, the same action is conducted with the addition of polycondensation products of acetone and formaldehyde concomitant with the addition of fly ash.

“…Bitumen comprises a complex combination of highmolecular weight hydrocarbons derived from petroleum, such as the naphthenic (С n Н 2n ), aromatic (С n Н 2n+6 ), and paraffin (С n Н 2n+2 ), together with its derivatives that contain complex metal compounds, oxygen, sulfur, and nitrogen. The main chemical composition of bitumen is carbon (70-87%), hydrogen (8-12%), sulfur (0.5-7%), oxygen (0.2-12%), and nitrogen (0-2%) [1][2]. The distribution of the molecular weights of the bitumen components obeys the law of normal distribution, which is also reflected in the nature of the changes in the rheological properties of bitumen in the plasticity range.…”

“…Several strategies are being used worldwide to improve the quality of asphalt binder. One of the classic methods is the addition of polymers to bitumen to change its characteristics [1][2]. It is well known that the most important condition for obtaining a high-quality asphalt concrete mixture is good adhesion of bitumen to mineral materials, which is ensured, first, by good enveloping and chemical interaction of the active components of bitumen with the mineral filler [1][2][3].…”

This article presents studies on the modification of petroleum bitumen with polymer waste in the presence of vermiculite. An increase in temperature leads to an increase in the interaction of components, partial breakage of polyethylene and bitumen macromolecules, and the formation of radical-free valences. As a result, fragments of polyethylene and bitumen molecules react with each other, and the formation of qualitatively new structural formations occurs via the strong connection of polar and amorphous bitumen with nonpolar structurally viscous polyethylene. Domestically produced Kulantau vermiculite was used to ensure stable adhesion over a wide temperature range and increase the specific surface area, which acquired additional energy, resulting in an increase in the degree of adhesion to bitumen and increased durability of the binder with improved rheological characteristics. Because of the increased service life of road asphalt pavements, the use of the latter results in a considerable decrease in the cost of polymer-bitumen binders. Based on improved binder formulations, asphalt concrete exhibits excellent water resistance and strength at 50 °C (4.7 to 5.0 MPa). In summary, the modification of bitumen with polymer waste and vermiculite offers a promising avenue for improving the performance and longevity of asphalt pavements.

“…In particular, military actions, the consequences of the COVID‐19 pandemic, economic transformations, and regional and social imbalances have had a negative impact. In such conditions, within the system of land relations, it is necessary to reconceptualize approaches to spatial, urban, environmental, and investment support based on the formation and implementation of a multi‐purpose cadaster as a single multilevel information system (Mamonov, 2018a; Yang et al, 2022). Land degradation is a serious problem in Ukraine, and the creation of a multi‐purpose cadastre can play an important role in combating this phenomenon.…”

Modern conditions in Ukraine require a rethinking of approaches to the formation of rights, restrictions, responsibilities, real estate accounting, and assessment of factors influencing these processes. Therefore, the article aims to identify the factors affecting the formation and use of the multi‐purpose cadaster as a multi‐level information system, which allows it to form a systemic environment and develop the theoretical and methodological foundations of the territorial development of regions. As a result, it is established that the multi‐purpose cadaster is a modern information system that forms the basis for the implementation of the European land administration system, provides land and real estate management, taking into account spatial, urban, environmental, and investment factors, and the level of stakeholder interaction at the regional level. Finally, the relevance of the research consists in the fact that military actions, the consequences of the COVID‐19 pandemic, deforming economic transformations, imbalances in regional ties, and social imbalances have a negative impact. In such conditions, the development and implementation of a multi‐purpose cadaster at the regional level are of particular importance, taking into account the impact of spatial, urban, environmental, and investment factors and European experience in implementing land relations.
