This research is devoted to modification of physical and mechanical properties and structure of a binder based on natural anhydrite. A sedimentary rock siltstone was added into the composition as a mineral ultrafine additive. The presence of aluminosilicate minerals proves that finely ground siltstone can be used as a mineral additive in the composition of the anhydrite binder, accelerating crystallization of gypsum new formations and densifying the structure of gypsum stone. For the first time, the effectiveness of using sodium and ammonium phosphates as hardening activators of an anhydrite binder was shown. Siltstone, added to the composition in the amount from 0 to 5%, lead to up to 40% increase in strength, which is due to the action of siltstone particles as “crystallization centers” and formation of crystalline hydrates of calcium sulfate dihydrate on their surface. Combined action of calcined siltstone and lime leads to a 45% increase in strength due to the additional compaction by new hydration products formed in the course of metakaolin and lime interaction. Microstructural analysis showed that samples with calcined siltstone and lime have a more dense and uniform structure with a lower porosity, compared to those with only natural siltstone.

The most important condition for the integration of the Russian transport infrastructure into the global logistics chain is the design and construction of high-speed railways. In the course of this research, the problems of implementation of high-speed highway “Moscow-Kazan” project by “High-speed Rail Lines” Joint stock Company were considered, and the necessity of large scale projects realization on high-speed railways construction was defined. Then, the aggregate demand values were determined, and the distribution of traffic between different transportation modes was predicted. Finally, the induced demand value was forecasted. Based on the predicted passenger flow characteristics, the indicators of train traffic were calculated. The passenger traffic on the road segment between Moscow and Kazan was studied. The methodology for passenger traffic calculation included the calculation of the induced demand, the possibility of passengers choosing the railway over other modes of transportation, and the evaluation of the demand fluctuations dynamics. The scientific novelty of this study is the application of an improved method of statistical analysis in the calculation of passenger traffic. Along with the theoretical results, the carried out research has an utmost practical importance-its results can be applied in the design of main railways.

The paper considers an issue of transition to digital management technologies in the field of construction and housing and communal services in Russia, as well as in other countries. An optimization methodology for the application of  the digital  economy  has been developed using  the example of  the existing  real  estate  management  system in the  Stolichny Microdistrict of Izhevsk city (Udmurt Republic, Russian Federation). The existing and developed new projects of digital technologies are described, the introduction of which will increase the efficiency of the construction and operation of residential buildings. A methodology has been formed for creating an optimization mathematical model for managing construction and operation projects of energy-efficient residential buildings. Prerequisites and a scheme for the joint implementation of this model and digital technologies are given to improve the quality of construction and operation of residential buildings. The paper proposes a phased methodology for the introduction of digital technologies in urban planning, as well as in the field of housing and communal services within the framework of the national program “Digital Economy of the Russian Federation”. The advantages of using block-chain technology in the management of projects for the construction and operation of energy-efficient residential buildings have been studied in the paper. The application of the developed methods that meet the needs of participants in construction activities, as well as the housing and utilities sector, will improve the efficiency of not only the management system for the construction and operation of energy-efficient residential buildings, but also the overall effectiveness of the introduction of digital management in real estate. The proposed ABRIS software can be used in housing and communal services to optimize and track the expenditure of resources vital for a comfortable living of the population.

The purpose of the paper is to analyze a market of territorial marketing as a special, significantly different from the commercial  market in the post-Soviet space.  Attempts to characterize this territorial  marketing market in general have not yet been undertaken. The authors have set a task to answer questions about their understanding of the territorial marketing essence; nature of interest of any territories in general and post-Soviet territories, in particular, in the use of marketing tools in its strategic development; territorial marketing market structure – customers of such services on behalf of territories, research organizations, marketing, advertising, design and other organizations creating convenient marketing products, and furthermore means for advertisement positioning and organizations providing opportunities for special events in the interests of territories promotion. On the basis of a comparative analysis of the territorial marketing markets of a number of countries leading in the post-Soviet space which are not members of the European Union, an analysis of statistical data and expert surveys, the conclusions have been made: Russia occupies the leading place in this field - and in absolute criteria (budgets, territories need), and in quality of work. But in the recent years Kazakhstan is actively developing territorial marketing technologies and this country is ahead of Russia in a number of areas. It is important that the territorial marketing markets of Russia, Kazakhstan and other post-Soviet countries are not isolated from international ideas and market structures. The main developments for the Russian territories are based on the ideas and methodology of the British school of territorial marketing. Foreign marketing structures, primarily from Great Britain and the Netherlands almost always participate (and often win) in significant tenders for territories ordering being held in Russia and other CIS countries.
