Published: May 2021

AbstractThe rational use of natural resources and environmental protection are crucial global issues. The article analyzes the experience of Russia and some foreign countries (Mongolia, China, and India) that have already launched a campaign aimed at developing environmentally friendly technologies. In Russia, this process has been recently initiated. The authors consider the problems of rational nature management in terms of protection of specially protected natural territories and implementation of innovative technologies by enterprises. Environmental threats hinder the development of specially protected natural areas and worsen the environment in specially protected areas. The article focuses on practical activities of environmental protection inspectors, presents statistical data on environmental offenses committed in specially protected natural territories of Irkutsk region. The development of environmental technologies is promising in Russia. “Green” and innovative technologies have already become the basis of many government policies and determine the development of new economic models. The experience of foreign countries shows a positive result of the use of the best available technologies, but the implementation of this mechanism requires time and various tools.

New information about the education of architect Robert Marfeld in the context of the influence of European architecture on the formation of the architectural identity of Irkutsk
Authors: Glebova N M , Klamer M , Alekseeva V O 
Published: May 2021

AbstractThis article aims to highlight the fact about the influence of European education on the work of the Russian architect with German roots, Robert Marfeld. On the basis of the collected bibliographic and archival materials, his projects and the work of his teacher - the famous Austrian architect Theophil Hansen, who taught a Master class at the Academy of Fine Arts in Vienna, worked with the greatest Austrian architects of the mid-19th century - are studied. In this context, a project of a vocational school in Irkutsk, carried out by Marfeld, is considered. The stylistic features of Marfeld’s architecture, especially in the initial period of creativity, are in many ways similar to the architecture of Hansen and his school. This is also due to the trends in architecture and construction of that period, especially in Germany and the Austro-Hungarian monarchy. Leading Russian architects were educated in Europe. European architects taught in St. Petersburg. Thus, the work of German and Austrian architects in Russia and in Irkutsk played a significant role in the formation of architectural identity, which contains many different characteristics, which was highlighted in previous articles by the authors, but also features inherent in the styles developed by the German and Austrian architectural schools.
Ceramics in architecture
Authors: Kulakov A I , Ri A U 
Published: May 2021

AbstractThe article analyzes the role of decorative ceramics in solving architectural problems of the traditional “architecture - painting - sculpture” triad and organizing the architectural and spatial environment. Ceramists use ceramics in unusual ways. Their solutions are crucial for the synthesis of arts. In the current architectural space, ceramics should not be considered as a building material or an element of the decorative or monumental arts. Its applications in the architectural spatial environment require studies of fundamental problems of the synthesis of arts. A literature review has identified an unusual pace of ceramics development. It penetrates into adjacent areas and shows a trend towards “omnipresence”. Therefore, a deep analysis of the ongoing processes is required. The appearance of a modern city is determined by the huge scale of construction. At the same time, the issues of emotional enrichment and individualization of the architectural space are acute. Irkutsk is famous for its rich historical experience in using ceramics as a building material. It is necessary to preserve the individual appearance of the city with a rich historical heritage. New applications of the ancient material are determined by its remarkable plasticity, color and texture properties. Combining plasticity and color, ceramics can be used as a material for monumental sculpture and jewelry modeling. It is cheap and possess good artistic and utilitarian qualities.

The song or arpentage? In the spatial context of the quarters of the historical center of Irkutsk
Authors: Selivanov R A 
Published: May 2021

AbstractProblem. In modern Irkutsk, the nature of the relationship between the cadastral plan of the quarter and its development is a problem. The essence of this problem is the inconsistency of the boundaries of land surveying with buildings on these sites. Goal to develop a methodology for interacting the spatial grid of a quarter with its cadastral plan. Results: A proposal is made for a method of shaping in the context of a historical city based on a spatial grid that includes a mechanism for interacting with the cadastral plan of the Irkutsk quarter. The analysis of the spatial situation of the historical quarter is performed. Spatial and contextual requirements for the proposed architectural object within the boundaries of this quarter have been developed. Conclusions: To get a high-quality project result in working with the districts of the city center of Irkutsk, a contextual approach is necessary, which includes, in addition to the traditional preproject analysis, research of the spatial structure of the historical environment of the districts.[11] The strategy of spatial development of blocks in the historical center of Irkutsk does not have clear and meaningful prospects without resolving the contradiction in the relationship between the compositional integrity of building blocks and their land surveying. An effective mechanism of urban planning regulation is needed to implement the design methodology of shaping in the context of a historical city based on a spatial grid.

The external diameters of the sections of the truss elements vary. A detailed algorithm for solving the problem is presented. The algorithm is implemented in the mathematical packageMathCAD, which allows you to visually trace the sequence of commands, as well as receive graphs reflecting the state of the problem at each iteration.
Strength of cellular concrete as a function of density under axial uniaxial compression
Authors: Savenkov A , Zaenec E , Ketner A 
Published: May 2021

AbstractThe purpose of this work is a comparative analytical assessment of the axial compressive strength of foam concrete depending on its density grade, taking into account strength losses in the presence of surface-active substances, porosity, and strength characteristics of the matrix material. The values specified in GOST 25485-89 and calculated according to the proposed analytical laws and regulatory data are compared. The effect of the foaming reagent on the strength of the foam matrix was evaluated in accordance with GOST 30744-2001 on standard samples-beams 40x40x160 mm in size from the control cement test without additives and with additives of synthetic and protein foaming agents of different concentrations in the sealer (from 0.3 to 3%). The degree of influence of the foaming agent on the strength of the finished foam concrete prepared using classical technology was performed on samples-cubes of 100x100x100 mm in size according to GOST 10180-90. The article presents the results of a study of uniaxial compression strength calculated for cellular concrete depending on the density grades known from these regulatory documents and other sources. Analytical expressions for determining the strength calculated for cellular concrete with an average density of 300-900 kg/m3 are presented. The proposed approach, based on the assessment of the initial data – the strength class of the binder, porosity, matrix strength, type and concentration of the foaming agent-allows us to predict the final strength of foam concrete products of this average density. Their rational accounting will help in the production of construction products of the maximum possible strength at a given density. This will expand the use of foam concrete in construction.

Published: May 2021

Abstract
Monolithic construction in winter faces problems of concrete strength set at negative ambient temperature. In order to ensure the necessary temperature conditions for hardening concrete use different methods of heating structures. One of the most effective ways is to warm up using a heating wire. The tasks of stood concrete in winter conditions are multifactorial, and computer modeling can significantly improve the efficiency of work. The ELCUT software complex is a tool in solving such problems, based on the method of the final elements. On the example of a monolithic foundation slab, the process of hardening of concrete at the temperature of the coldest five-day and medium-winter in Bratsk was simulated. The calculation of the concrete strength set and the analysis of temperature fields, taking into account the requirements for crack resistance, has been made. Computer simulations allowed to pick up the parameters of laying the heating wire in the concrete.

AbstractThe Russian government sets global strategic goals for increasing the volume of housing construction-mass multi-storey, multi-apartment and residential housing, creating a comfortable urban environment, comprehensive development of rural areas, construction of social infrastructure facilities in small towns and villages of the country, designated in the national projects “Health”, “Culture” and “Education”. The state assigns a key role in their implementation to modern wooden construction. Recently, many interesting projects have appeared in the field of wooden housing construction. There is a noticeable interest of the state in the development of this area, which is primarily due to the focus on the efficient use of the country’s forest resources, as well as the fact that wooden housing construction, due to the high degree of factory readiness of building elements and structures, creates products with high added value and the most transparent from the point of view of taxation, when compared with other areas in construction. Despite this, the potential of wooden construction is not fully disclosed, which does not allow to ensure their environmental friendliness, comfort and energy efficiency. The purpose of the article is to achieve high rates of individual housing construction through a combination of measures aimed at increasing its liquidity. The article analyzes the market of wooden housing construction in Russia, which allowed us to determine the promising construction technologies of the housing construction sector under consideration. The main properties of wood, its advantages and disadvantages are considered. It is determined that the development of industrial housing construction of individual residential buildings will allow not only to implement the tasks of national projects in Russia, but also increase the flow of investment in the construction of individual residential buildings using the industrial method, which will support enterprises that produce factory-made house sets. Based on this, the article contains recommendations for improving the quality of wooden construction products at all stages of the construction life cycle, the implementation of which will generate demand for wooden housing construction, ensuring the rational use of wood and high quality for consumers of products.

The field of application of road transport in the delivery of drinking water and wastewater disposal
Authors: Chupin V R , Moroz M V 
Published: May 2021

AbstractDue to the uneven distribution of water resources across the territory of Russia, many settlements and even cities do not have their own sources of water supply and reservoirs, where treated wastewater could be discharged. Group and regional water supply and sanitation systems are being designed, built and developed to solve this problem. The length of such systems is hundreds and even thousands of kilometers. The construction and operation of such structures requires significant annual financial investments. Therefore, the choice of routes, the composition of structures, and especially the methods of transporting water and wastewater, justifying the location of water intakes and treatment facilities are relevant and require special attention and a feasibility study of design options. Based on the method of redundant design schemes, the paper proposes an integrated approach to optimize structures and methods of supplying water to consumers, transporting wastewater to treatment facilities by pipeline and road transport.
