Antonova I.I.,Ayupov D.A., Khakimullin Y.N., Khozin V.G  Bitumen emulsions for waterproof and roof coverings Стр.6
Resume:

bitumen emulsions are widely used in road construction. The main quality of bituminous emulsions is stability during storage and transportation: they should only break down while contacting with the surface. Anionic emulsions used in waterproofing of buildings and structures are less common due to their lower stability. The preparation of stable bitumen emulsions is impossible without the use of surfactants having necessary emulsifying and stabilizing properties. There are many chemical compounds that can be used to emulsify bitumen, but for technical and economic reasons, only a small number of them have become widespread. The aim of the study is to develop the composition of an aqueous emulsifier solution that ensures the stability of the bitumen emulsion and a high complex of properties of the binder obtained from it. To achieve the goal, the following tasks were solved: 1. Synthesis of an effective surfactant from the target domestic raw materials, which will ensure the consistency of composition and properties. 2. Determination of the selected surfactant influence on the properties of bituminous emulsions and binders obtained from these emulsions. Results. The main results of the study are to determine the optimal content of the surfactant, which will provide a high complex of properties of the emulsion and the binder obtained from it. Conclusions. The significance of the obtained results for the construction industry consists in increasing the storage stability of bitumen emulsions used for waterproofing buildings and structures.

Ignatyev A.A.   Additives in asphalt concrete. Literature reviewСтр.14
Resume:

Statement of the problem. Recently a lot of attention has been paid to the problems of improving asphalt concrete. This is due to the need to extend the service life of asphalt concrete pavement in conditions of constant growth in traffic loads, intensity of traffic and climatic factors as well as the need to extend the functional properties of the pavement. The purpose of the study is to determine the prospects of development and directions of improvement of asphalt concretes. The aims of the research are to analyse the works of domestic and foreign researchers aimed at examining the characteristics of asphalt concrete by introducing additives and new components into asphalt concrete mixture and identify the directions of asphalt concrete development. Results. During the research review, four main vectors of asphalt concrete development were identified. The first one is aimed at the introduction of additives able to provide self-healing of pavement microcracks when microwave exposure is used. The second vector is more promising and can rather be attributed to the concept of "smart" materials, where the input additives provide an opportunity for asphalt concrete pavement to use technologies widely used for intelligent transport systems due to the electrical conductivity of the mixture. The third vector is related to the search for options to replace the main binder (bitumen) with other types of binders or to evaluate the possibility of using combinations of binders, such as cement and bitumen simultaneously. The fourth vector is aimed at evaluating the additives introduced directly into the asphalt concrete mixture itself in the form of various fibers, both of natural origin and artificially obtained. The range of applied fibers is very diverse and the works devoted to these researches are quite numerous. Conclusions. The results of the researches allow establishing modern tendencies in the development of asphalt concrete coatings and estimating perspective additives in asphalt concrete which provide increase in operational characteristics and formation of new demanded properties of coatings that gives the grounds for further researches.

Mirsayapov Ilshat T., Valiev A.T.  Study of the stress-strain state of steel reinforced concrete beams of the new type railway bridgesСтр.31
Resume:

Problem statement. When designing steel reinforced concrete railway bridges over the carriageway, there is often a question of limiting the height of the structure due to the fixed elevation of the bottom of the bridge. In order to achieve the required strength of such structures, it is necessary to increase the thickness of walls and flanges of the steel part of the beam while the working height remains unchanged, which leads to considerable overconsumption of metal. One way of solving this issue could be the use of composite beams of a new type, where the steel I-beam is partially brought into the concrete of the compressed zone. The study is aimed at determining the stress-strain state of steel reinforced concrete beams of the new type on the basis of numerical experiments. The tasks of the study are computer modeling of the deformation and fracture process of the calculated models and a comparative analysis of the results. Results. Numerical modeling has been used to reveal the spatial operation of steel reinforced concrete structures. A numerical experiment was performed using the ANSYS software package in the Workbench shell. The computational model was corrected according to the results of in-situ tests by other authors. According to the results of the calculation, the deformations and stresses in the beam were obtained. A comparative calculation found that taking into account the true cross-section of the model increases the load-carrying capacity of the structure by 10%. Conclusions. The significance of the obtained results for the construction industry lies in the fact that they allow estimating more accurately the bearing capacity of the proposed new type of steel-reinforced concrete beams section. The results of the study can also be used for the introduction of new types of beams in Russian standards of steel reinforced concrete design and development of new methods of calculation of such structures.

Broida V.A.   Analytical study of the operation of the natural exhaust ventilation system of a multi-storey building with air flow stabilizers in the cold seasonСтр.43
Resume:

Formulation of the problem. Natural ventilation is widely used in buildings for various purposes. When the outdoor temperature drops, the consumption of supply and exhaust air increases, which leads to an increase in the cost of thermal energy during the cold season. The research aimed at eliminating this problem is relevant. To prevent an increase in ventilation air flow, air flow stabilizers can be used - direct-acting regulators or conventional automatic regulators using external energy sources. Stabilizers can be installed on intake devices or on exhaust channels. In multi-storey buildings, exhaust systems are often common to all or several floors. Homeowners could install air flow stabilizers to improve the properties of their ventilation systems. The purpose of the study is to analytically determine the effect of installed flow stabilizers on the change in exhaust air flow in branches where flow stabilizers are not installed, as well as in other sections of the exhaust natural ventilation system of a multi-storey building. The research objectives are: to build an analytical model to study such influence; to perform calculations and determine the change in air flow depending on the floor, on the branch of which there is no flow stabilizer and the change in flow in the rest of the system and the entire system as a whole. Results. Analytical dependencies are obtained and the analysis of the impact of the use of flow stabilizers not on all floors of a multi-storey building is carried out. It has been established that on the floors where stabilizers are not used, the exhaust flow rate increases significantly. Also, the air flow increases in the remaining sections connected in series and in the system as a whole. Conclusions. The significance of the obtained results for the construction industry lies in the quantitative assessment of the impact of the use of stabilizers not on all floors of the natural ventilation system of a multi-storey building, which makes it possible to consciously choose the use of air flow stabilizers when installing such systems.

Busarev A.V., Sheshegova I.G.  Purification of natural waters from borate ions using ion exchange Стр.52
Resume:

Problem statement. Purification of natural waters from boron compounds is of scientific relevance, since it allows solving the problem of providing the population with high-quality drinking water. One of the ways to purify natural waters from boron is the ion exchange method. The aim of the work is to conduct research on the removal of boron from water using pressure ion-exchange filters. The objectives of the work are: to study the processes of purification of boron-containing waters in pressure ion-exchange filters with various ion-exchange resins; to determine the effect of filtration rate on the cleaning efficiency; to determine the effect of pressure in pressure filters on the cleaning efficiency. Results. The main results of the research are that the efficiency of water purification from borate ions on various ion exchangers is determined, the influence of filtration rate and pressure in pressure filters for the purification of boron-containing waters is determined. Taking into account the results of the research, a plant for the preparation of water containing high concentrations of boron for household and drinking needs has been developed. Conclusions. The significance of the obtained results for the construction industry consists in improving the quality of the preparation of boron-containing groundwater. The most effective ion-exchange loading and technological parameters of purification of boron-containing waters in pressure ion-exchange filters have been determined. The best result (cleaning effect 71-87%) was shown by Granion D403 brand ion exchanger. Studies have shown that an increase in the filtration rate in ion-exchange filters reduces the efficiency of their work, and an increase in pressure at the inlet to the ion-exchange filter does not affect this value. An installation for the preparation of groundwater with a boron content of up to 2.3 mg/l with a capacity of 200 m3/day has been developed.

Kupriyanov V.N., Mirsayapov I.T., Saifullin I.F., Khairullina A.T.   The potential of project activities in the study of architectural identityСтр.84
Resume:

The relevance of the article is due to the fact that there are gaps associated with the practical study of architectural identity in the modern educational process aimed at architecture specialty training. The lack of in-depth knowledge and practical skills in this area leads to errors in architectural design, as a result of which the appearance of cities and settlements suffers significantly. The environment arising in the process of the same type of construction is uncomfortable for living and does not fulfill the main role of architecture as an environment reflecting the socio-cultural values of a particular region. The purpose of the article is to substantiate the application of design teaching methods in the study of the architectural identity of cities and rural settlements. The authors propose a model for organizing the project work of architecture students in the study of architectural identity. The article is intended for teachers of higher educational institutions.

Aidarova G. N., Kupriyanov V. N., Mirsayapov Ilizar T.   Syuyumbike Tower in the context of the architectural typology of Eastern Muslim and Bulgaro-Tatar towers and tower minaretsСтр.159
Resume:

Problem statement. The Syuyumbike Tower is an architectural monument of world importance, which is a part of the Kazan Kremlin ensemble under the protection of UNESCO. It has no exact attribution. The existing hypothetical dating covers the first half of the 16th–first third of the 18th centuries. The purpose of the article is to substantiate the hypothesis about the possibility of creating the Syuyumbike Tower in the Kazan-Khan construction period as an object of civil and religious purposes as a part of the Khans palace complex. The tasks include: identifying analogues of tower architecture of the Islamic Middle Ages, identifying the architectural and typological characteristics of the Syuyumbike Tower in comparison with regional and Eastern Muslim civil-cult tower architecture, as well as with regional fortification and civil tower structures; identification of structural-typological, socio-functional characteristics of Syuyumbike tower in the context of Islamic regional traditions. Results. Based on the analysis of literary, natural and information-illustrative sources, tower-type minarets of the 9th-16th centuries were identified and classified. On the basis of analogues, the types and features of the tower minarets of Bilyar and Bolgar (cylindrical-tiered) are determined, the types of towers are hypothetically determined on the basis of archaeological and historical-architectural research data: «Small town» in the Bolgar settlement (over-gate-tiered type); towers of the Kazan Kremlin: North tower-prismatic structure; fortification-gate at the Tezitsky moat, non-fortification-gate at the Khans court. On the basis of a comparative analysis, the typological characteristics of the Syuyumbike Tower were revealed. Conclusions. Based on the results of a comparative typological analysis, it was hypothetically established that the Syuyumbike Tower is in the context of the Bulgaro-Tatar traditions of tower architecture, tower minarets, which is a natural stage in their development. According to the sum of the identified features, the type of the Syuyumbike Tower was hypothetically established as a gate tower for civil and religious purposes, which has a polygonal-tiered structure; the purpose corresponds to the functions: patrol and observation (control of the surrounding territory), religious (minaret), administrative, astronomical. The significance of the obtained results lies in the substantiation of the scientific hypothesis about the possible belonging of the Syuyumbike Tower to the construction period of the first half of the 16th century as part of the Khans Palace complex, as well as the need for further research based on the latest instrumental methods.
