“…It should be mentioned that the system analysis of energy consumption in the sphere of gas and energy supply [1,24] makes it possible to plan the ways of increasing energy efficiency of the gas and transport system [7][8][9]22,23], buildings and structures on the stage of their planning, construction and exploitation [25][26][27][28]. Ultimately, it leads to the development of future-oriented national technologies, decrease of energy consumption of objects of infrastructure, successful import substitution politics on the territory of the Russian Federation.…”

The paper introduces a new technology of isothermal pressure regulation of natural gas based on temperature stratification which combines the vortex effect temperature stratification and supersonic gas-dynamic temperature stratification. The authors simulate physical and numerical controllers work. As a result of the experiments the most effective operating principles of the isothermal controller (based on the vortex tube temperature stratification) are introduced. The paper also presents calculations of the described pressure regulation controller while applying gas-dynamic temperature stratification. The authors conclude that the usage of the introduced technology of isothermal pressure regulation of natural gas will reduce expenses of gas transportation systems for their own needs (by 0,08-0,2 % of natural gas to their carrying capacity).

“…Water absorption, clay particles content and strength are usually named among the main characteristics of concrete fillers [2,5,12,[19][20][21][22][23]. The quality of concrete filler affects durability and safety facilities as well as economic efficiency of building materials based on recycled concrete.…”

Abstract. By now, the wear and tear of housing stock is more than 50%. Each year the number of old and dilapidated housing is growing, but it is gradually replaced by modern buildings. However, wastes accumulated from dismantling of buildings and constructions, are underutilized and, usually are just stored at landfills, or used for temporary roads construction. The purpose of this research is to define construction wastes characteristics and to explore possibilities for recycling of wastes from construction materials production. The paper also analyzes housing stock condition and basic requirements to building materials used in construction; and demonstrates results building materials based on secondary gravel investigation. While working with materials based on waste requirements the authors conducted laboratory research. Thus, the paper presents the analysis of laboratory tests results that made it possible to draw conclusions about the possible use of building materials based on secondary gravel and about their conformity to specified requirements. The researchers also developed proposals and recommendations to improve the competitiveness of such materials.

Abstract.The results of research of activity enhancement of natural siliceous raw material are given in the article. Fossil meal of Khotynetsky deposit, diatomite of Sharlovsky deposit, silica clay of Balasheika deposit were used as natural active mineral admixtures. The influence of heattreating temperature and dispersion on activity of different types of siliceous raw material is studied. The increase of activity of fixation of Са(ОН) 2 in several times is traced after heat-treating at a certain temperature in the range from 100 to 800 0 С. The type of activity change is discovered. Explanation is given connected with the change of silica structure in the surface layer. Parameters of the highest activity are defined for every type of siliceous raw material.
