Gas-hydrodynamic characteristics of aerotanks
Authors: Kul’kov V N , Yu Solopanov E 
Published: July 2020

Abstract
The purpose of the research was to determine the hydrodynamic indicators of aerotanks determining the depth and effectiveness of wastewater treatment. The study of technological parameters of the aeration tank was carried out on a physical model representing a transverse vertical section of the aerotank. The hydrodynamic similarity in the model and industrial aerotank determined by the identical values of the Reynolds, Froude, and Euler criteria. The study of similar indicators on an industrial aeration tank is very difficult and costly. The model and experimental setup make it possible to vary in a wide range the intensity of air aeration, the design and location of the aerator, control the speed of hydrodynamic flows and the concentration of freely floating sludge in the facility with aeration. To study the gas-hydrodynamic indicators in the aerotank model, original methods based on the laws of physical chemistry have been developed and used. The contact surface of the phases “liquid - gas” from the intensity of air aeration was determined using a chemical method for aerated biological wastewater treatment facilities. The dependences of the specific contact surface of the phases “liquid - gas”, referred to the unit of the working area of the aerator, on the intensity of aeration and the depth of immersion of the aerator are obtained. The oxidizing ability of a fine bubble aerator was determined for various aeration intensities. The dependences of the oxidizing ability on the contact surface of the phases ‘liquid - gas” in aerotanks were obtained for the first time. It is shown that the oxidation ability of the aerotank is determined by the phase contact surface and, to a large extent, by the hydrodynamic situation in the aerotank, which forms the fields of freely floating activated sludge.
Discrete continuous mathematical models in the dynamics of horizontal vibrations of buildings
Authors: Sobolev V I , Druzhinina T Y 
Published: July 2020

AbstractIn the design practice of design, dynamic models are used, based on the discretization of structures whose inertial parameters are always distributed. The use of discretized models leads to the formation of large-dimensional problems, and the estimation of discretization errors is extremely complicated by the presence of constructive irregularities and heterogeneities of the boundary conditions of the calculated objects. In view of the foregoing, the proposed work is devoted to the formation of mathematical models that allow combining elements with concentrated inertial parameters (discrete elements) with deformable elements whose inertial parameters are distributed (continuous elements). The need for the formation of such models arises, for example, when calculating buildings for horizontal dynamic effects and also when solving the problems of dynamic analysis of building structures with the presence of vibroactive technological equipment.
Research of composite binders with nanomodifiers for dry mixes
Authors: Urkhanova L , Lkhasaranov S , Badmaeva E 
Published: July 2020

AbstractThe article discusses the application of various mineral materials for the modification of Portland cement in order to obtain dry mixes. The main component in the composition of dry mixes is Portland cement, affecting its physical, mechanical and technological properties. To modify Portland cement, which is used to obtain dry mixes, various micro- and nano-additives were used: volcanic slag, microsilica, nanosilica. Mechanical parameters of modified Portland cement at various hardening periods are determined. The introduction of micro- and nano-additives positively affects the hydration process of Portland cement, which is confirmed by the study of the microstructure of the modified cement stone using scanning electron microscopy. It has been established that when using various micro- and nano-additives, the amount of low-basic calcium hydrosilicates changes, affecting the increase in the mechanical properties of cement stone. The use of volcanic slag and nanosilica allows to improve the technological and quality indicators of dry mixes. Studies of determining the angle of repose of the composition of composite binders based on Portland cement and volcanic slag, as well as the introduction of nanosilica in Portland cement show a significant change in this indicator indicating an improvement in the flowability of the material.

Published: July 2020

Abstract
In today’s world, environmental issues are becoming increasingly important and relevant. The housing and communal services system is often one of the main sources of anthropogenic impact. So, when receiving thermal energy by burning of organic or mineral fuel, various types of pollutants enter the atmospheric air. In this paper, a comparison of gross emissions into the air during operation of a heat source using fuel oil and wood fuel (pellets) is made. An analysis of the results was carried out. It showed that the most “environmentally friendly” are heat sources, the main equipment of which includes boiler units burning wood fuel (pellets). With the operation of this type of boiler, the level of anthropogenic load in the form of pollutants emissions is significantly reduced, in particular, there is a multiple decrease in emissions of pollutants of hazard class III.

Authors: Kulakov A I , Krakovtseva Yu V 
Published: July 2020

Abstract
Developing modern-day railway stations as a rule goes along with their working. While being reconstructed, the arranged activity of railway stations has to be in-process. Railway stations have to function consistently and continue their work when providing services. To realise large-scale concepts, developing and building activities are implemented through a step-by-step approach with each building stage being autonomous. It means that the functioning of the reconstructed object is in-process when the developing works are under way. The process requires that there should be a close-cut separation of the functional zones, as well as there should be a coherent scheme to serve passengers.

Smart technologies as a type of intangible assets of a construction organization and mechanisms for their implementation
Authors: Peshkov A V 
Published: July 2020

AbstractThe company’s assets include intangible assets, a distinctive feature of which is the absence of physical assets. Today, it is becoming more obvious that the so-called tangible assets are not the only factor in ensuring the profitability of the organization, and that there are other types of them that do not have such a classic feature as a material substance, but can play a crucial role in the process of making a profit for the enterprise. The relevance of this topic is obvious, because in modern conditions, the formation of complete information about economic processes is almost impossible without information about intangible assets. Moreover, with the development of innovative technologies, organizations in the construction industry need to step forward and use such type of intangible assets as Smart platforms. This type of intangible assets allows construction companies not only to meet a high innovative level of development, but also provides a reduction in costs and generate more revenue.

Authors: Nikityuk L G 
Published: July 2020

Abstract
The state of the housing and utilities sector is one of the most significant indicators of the level of development of the national economy. In many countries, the state of the housing and utilities sector does not fully satisfy needs of the population. Under the slow economic development, an innovative development path can ensure high quality and reliability of services provided. The concession mechanism of cooperation between government and businesses should become a key tool which can attract investment in the development of innovative activities in the housing and utilities sector. The author has developed a support scheme for the investment and innovation project implemented in the housing and utilities sector using a concession agreement within the PPP which ensures stability of the industry and improves quality of services provided. The scheme of concession tools can be used to achieve a social and economic effect. The article presents a method for assessing the economic effect of concession agreements used when implementing the investment and innovation projects in the housing and utilities sector taking into account risks. It can balance interests of the government and housing and utilities companies. The concession mechanism will contribute to the development of the most promising areas of the housing and utilities sector.
Cost optimization for overhauling the apartment blocks in Irkutsk, Russia

Published: July 2020

Abstract
This paper analyzes the specifics and major shortcomings of the following documents: the Irkutsk Oblast Act No. 167-OZ of December 27, 2013 On the Arrangement of Common Property Overhauls in Irkutsk Oblast and the pertaining regulations, programs, and Short-Term Plans Under the Irkutsk Oblast Regional Apartment Block Overhaul Program (hereinafter, common property stands for common facilities used by the residents of a single apartment block, e.g. rooftops, utilities, etc.). It further analyzes the financial reports of the Irkutsk Oblast Apartment Block Overhaul Fund. The analysis demonstrates the costs of overhauling the apartment blocks in Irkutsk Oblast with breakdown by sources, the amount and source of funds coming from the region’s municipalities as shown in the general funding structure of the Plan, and the specific jobs arranged under the City of Irkutsk Short-Term Plan Under the Regional Apartment Block Overhaul Program in 2015-2016. To simplify the drafting of overhaul programs, the authors hereof present the estimates of roof overhaul costs per square meter with breakdown by overhaul-related jobs; the estimates assume the use of novel materials: MasterSeal*501 and MasterEmaco*S 48. Such analysis reveals the roof job-specific coefficients (multipliers) one needs to apply to find the actual overhaul costs for Series 135 panel buildings in Irkutsk. The authors propose an scenario-based approach to design when drafting time-adjusted short-term overhaul plans. Time adjustment helps optimize such plans and minimize the change of a building being classified as a dilapidated apartment block.

Published: July 2020

Abstract
Equity construction is actively developing in the Russian Federation. At the beginning of the second half of 2018, there were fundamental changes in the Russian real estate market. Federal Act No. 1 of 2018 July 175-ФЗ was adopted, amending the Act of 2004 on the procedure for citizens ‘participation in equity construction. In particular, the system of subsidization of objects under construction has been completely revised - the equity participation was replaced by the mechanism of project financing. Federal Law No. 175-ФЗ changes the legal and regulatory regulation of housing construction, defining project financing as the only source of attraction of funds to equity construction. In this regard, interest in investments in real estate is growing, and there is an increase in interest of private capital in the housing industry. Thus, today the real estate market is changing, construction companies adapt businesses processes to new requirements. In order to assess the impact of escrow accounts on the real estate market, a comprehensive analysis of market development should be carried out and trends in development should be monitored.

Authors: Kretov Anatolii 
Published: July 2020

Abstract
The work is devoted to the rapid assessment of the weight of the aircraft and its design. This problem occurs when creating new aircraft or in the process of constructive improvement of existing ones. To determine the mass of the entire aircraft, the method of “mass change coefficients” (growth coefficients) is used, which is based on the equation of the existence of the aircraft. To analyze the mass of initial design changes, the Komarov weight formula based on the concept of “load-carrying factor” is used. The article considers a numerical example of estimating changes in the mass of an aircraft due to the use of composite materials in the fuselage structure.
