Published: December 2019

Abstract
With an analysis of world practice in the production of non-shrinkable and expandable cement mortars and structures, the basic methods for their preparation are revealed. The main directions of their production are established based on the use of special expanding cements developed by various authors. An analysis of the above mentioned methods revealed that for the Republic of Armenia the most accessible method is the development of a special additive and its introduction into conventional Portland cement.
Investigating the mineral base of the RA, a special additive was developed on the base of dust absorbed from exhaust gases of cement plants furnaces, by which it is possible to obtain non-shrinkable and expandable cements. Different ratios are determined at 800-1100 °C.
The study revealed that at a ratio of 40:60 and 45:55 (gypsum: dust), the additive obtained at 1000°C contains a sufficient amount of ettringite, the main mineral for expansion. The expansion effects of the developed additives were studied, its optimal ratio corresponding to 10 percent by mass of cement was established.

The composition theory in design and the industrial equipment design
Authors: Popov A D 
Published: December 2019

Abstract
The author offers (explains) his vision of the composition notion in engineering. Since the time of William Morris, his motto “for the connection of arts and crafts” has been raising doubts concerning the compatibility of these concepts. But the well-known formula “Ugly is not for sale” forced a human to relate more deeply on the creative process when creating machinery and machines in which he had already seen more than just mechanical parts connections. Therefore, the harmonization of the rich and complex world of the objective forms is the main task of the social tasks of our time. The article is devoted to the use of the composition theory laws (problems of tectonics, proportionality and scale) in the design of industrial process equipment.

Authors: Safaryan A 
Published: December 2019

Abstract
For the first time, it is proposed to create a network of ethnographic parks of the Armenian nation both in the territory of the Republic of Armenia, in Ararat, Gegharkunik, Shirak, Lori, Syunik marzes and abroad, preferably in largely populated Armenian diasporas of the United States, Russia and France. The problem of creating the main "Armenia of all times" ethnographic park where the creative achievements of the Armenian people around the world could be summarized and the Pan-Armenian Center for Armenian Studies in the Ararat marz arises again. Proposals for zoning the territories of ethnographic miniature parks and the representation of ethnographic parks by regions in Armenia are given. It is also proposed to create ethnographic miniature parks in the territory of the Mkhitarist Congregation Monastery Complex on the island of St. Lazare (Italy) and the Armenian Apostolic Church in the Church of the Assumption of St. Mary the Virgin in Armavir (Russia).

The influence of the electric field on the ice-forming properties of the reagent in the implementation of various mechanisms of crystallization
Authors: Khuchunaev B M , Tashilova A A , Teunova N V , Budaev A Kh 
Published: December 2019

Abstract
The features of the formation of ice crystals on reagent particles in a cloudy medium in the presence and absence of an electric field have been studied in the work. A complex of equipment from the laboratory of cloud microphysics of the High-mountain Geophysical Institute, which includes a sublimation chamber, a small cloud chamber, and an installation for bubbling reagent particles, was used. As a result of the experiments, it was found that when the condensation-crystallization mechanism is implemented, the specific yield of ice-forming nuclei in the cloud chamber decreases with increasing electric field intensity. When implementing the immersion mechanism, the electric field does not affect the specific output of ice-forming nuclei. In the case of a contact mechanism, the specific output of ice-forming nuclei is 2–3 orders of magnitude smaller than with the realization of the condensation-crystallization and immersion mechanisms.
Lightning activity over anthropogenic and natural landscapes
Authors: Ershova T , Punge H J 
Published: December 2019

Abstract
The analyses specific threshold of lightning discharges density and thunderstorms days for different type of landscape and level of altitudes were determinate. For Central Europe from 9° W to 20° E and from 42° to 56° N (11° x 14° sectors) for April–September period from 2001 to 2014 were investigated. For Europe for the altitude range from 10 m below sea level (bsl) to 200 m above sea level (asl) the highest lightning discharge density is associated with the forest, shrub and wet, urban areas. For the altitude range 200–1000 m asl the highest lightning discharges density is associated with water (river, lakes), urban and forest areas. For the altitude range level from 1000 m asl to 2000 m asl the highest lightning discharges density is associated with the water, forest and grass types. A dense forest on the track of the flow of a moist air mass can promote the rise of air and the formation of convective clouds and lightning strokes. The effect of rives, channels and large lakes on moisture and development of thunderstorm clouds may account for impact on cloud-to-ground (CG) lightning activity. For three flat 3° x 5° areas with similar meteorological and synoptic conditions, increased CG lightning activity is possible if there is a difference in altitude between different types of landscapes. The altitude difference further contributes to the development of convective clouds producing lightning.

Engineering exterior translucent coatings with the use of profile glass and composite materials
Authors: Abramyan S G , Polyakov V G , Oganesyan O V 
Published: December 2019

Abstract
The paper raises certain questions concerning the use of structural glass (glazing) in external vertical enclosures of modern construction systems, pointing to the need for combining composite materials, especially composite foam, in translucent enclosures, which helps dramatically reduce the weight of external panels while improving their heat and sound insulation performance. It also emphasizes the relevance of energy efficiency at the building operation and building construction stages, as energy efficiency is not only the heat saving performance during building operation, but also a high effectiveness of the construction technology.
The novelty of the study lies in engineering a wall panel possibly combining two materials — profiled glass and composite foam. The paper not only details the panel design, but also describes the manufacturing technology and the envelope arranging processes with two wall panel attachment methods and related joint assemblies. Based on a number of scientific publications, the handling mechanisms are discussed suitable for different ways of coupling the structural elements — wall panel and floor slab. Focusing on box-type structural glazing, the authors stress the need for further study involving other types of structural glass (channel shaped, ribbed, trimmed) to create multicomponent wall panels for a variety of regional climate conditions.
Organizational and economic problems of ecological safety in construction
Authors: Azarov V N , Manzhilevskaya S E , Petrenko L K 
Published: December 2019

Abstract
Nowadays it is necessary to make the environmental impact assessment (EIA) in order to identify, analyze and take into account the direct and indirect effects of environmental impact during the planning of design consideration for construction projects. The results of this assessment determine the aftereffects of a certain construction project’s implementation. These results are the objective information about the future state of the environment of the territory for making decisions on the implementation of the planned project.
The economic component of this assessment is the determination of the cost of implementing measures to protect the environment of a given territory. Current design trends have a tendency to change the criteria for planning the construction projects. It is important to make the managerial, technical and commercial decisions during the project development in favor of the environmental safety of the construction industry. During the criteria of the assessment development, it is necessary to take into account the prevention measures. It is important to prevent the pollution but not to monitor and eliminate the negative effects.
This article considers an example of the calculation of the criterion for choosing the environmental pollution control measures which can reduce the construction cost. These calculations make it possible to determine the environmentally and economically suitable area for the construction of an object in the populated area.

Program-target approach as a basis for issuing a backlog in construction
Authors: Zilberova I Yu , Tomashuk E A , Bobkina V A 
Published: December 2019

Abstract
During the last decades, the problem of maintaining the level of the housing stock was solved by the residual principle. The low quality of housing due to the use of short-lived materials and projects not reflecting the real objects’ state has led to accelerated rates of physical and moral deterioration of buildings. Implementation of the overhaul program is one of the priorities, but despite its significance, a number of problems of its implementation have been identified. The planning methods currently used do not properly reflect the changes taking place. The article proposes one of the possible solutions to the difficulties arisen, namely, the formation of a backlog on the program-target approach basis. Construction companies must diversify their backlog taking into account the existing workload and the lot structure determined by the customer.
