SAWMILCOBETONE ON NON-CEMENT COMPOSITE BINDER
Authors: V.V. Belov
Abstract: Abstract. The role and advantages of products based on a non-cement binder using wood waste compared to other types of materials and technologies are considered. The purpose of this work was to obtain a heat insulation material based on wood processing waste and non-cement binder. The cement-free binder material using sawdust as an aggregate is effective under real-world production conditions.
Keywords: Keywords: no-cement binder using woodworking wastes, heat insulation material, composition selection, mathematical experiment planning.
RESEARCH OF THE PATTERNS OF DEFORMATION
ALONG CURVILINEAR TRAJECTORIES OF CONSTANT CURVATURE
WITH A CHANGING PROCESS DIRECTION
Authors: V.V. Garanikov, E.O. Kornilev
Abstract: An experimental study of the vector and scalar properties was carried out when changing the direction of deformation on samples made of 9X2 steel. It is shown that after the exhaustion of a certain interval of the trajectory lengths, scalar and vector properties seem to forget the change in the direction of deformation and correspond to the trajectories without changing the direction.
Keywords: research, trajectory, scalar properties, vector properties, deformation, direction of deformation, delay trace.
ROLE OF OPTIMAL GRANULOMETRY
OF LIMESTONE ADDITIVE WITH NANOSIZED COMPONENTS
IN PRODUCTION OF BUILDING COMPOSITES
Authors: P.V. Kuliaev, V.V. Belov
Abstract: The article highlights the role of the nanoscale component of the western additive in various aspects of its application. Among inert and pseudoinert additives in concrete, carbonate additives are among the most significant. It is noted that particles of nano-sized composite of finely ground limestone powder under condition of uniform distribution inside matrix of composite play an important role in control of concrete hardening process. This issue is considered in light of internal processes of filling with limestone powder of matrix, strengthening of composite structure through influence on process of hydration and wrapping of cement nuclei reinforcement of matrix at micro level (increases strength, cracking and acid resistance of concrete).
Keywords: nanoparticles, nanoscale component, toned limestone powder, cement cores wrapping, reinforcement at micro level, optimal granulometry, highest particle packing, software modeling.
RANDOMIZING TOPICAL ISSUES
REGIONAL DESIGN AND CONSTRUCTION COMPLEX
Authors: V.V. Fedorov, T.R. Barkaya
Abstract: The level of innovation of design, construction and technical and operational activities in modern cities is estimated. There was a need for a systematic approach to identify and address key industry problems. The possible methodology includes the selection and justification of technologies, space planning and architectural and structural solutions; analysis of interaction of architectural and landscape environment with artificially introduced abstractions, myths, symbols, ideal models and sign objects; combining the results of empirical data with the conclusions and consequences of «thought experiments» based on the use of modern IT-technologies. It is shown that a characteristic feature of the sphere of professional activity is the comparable scale of current problems solved at the regional and national level. We are considering the randomization of problems, the next relevant plan for linking to stages of the life cycle of a building/structure. The results of comparative analysis of industry complexes of different constituent entities of the Russian Federation are presented. The phenomenon of «unrealizability» of completed and funded projects is described.
Keywords: design and construction complex, construction object, life cycle of building/structure, randomization of current problems of industry.
UNIVERSAL ENERGY-SAVING DESIGN
BASED ON RENEWABLE ENERGY SOURCES
Authors: S.V. Cheremnykh
Abstract: The aim of the research is to ensure energy and, as a result, environmental safety of regions with non-traditional energy supply by developing reliable and sustainable structures using renewable energy sources. The main objectives of the research are: to study the experience in the field of obtaining and using wind and solar energy, as well as its combination; to justify the need to use environmentally friendly methods of generating electricity; to develop a standard design and management system based on renewable energy sources; calculation of electrical circuits for obtaining, storing and transporting energy fr om natural sources. The method of solving the research tasks is: theoretical analysis, systematization, comparison and correction of new and previously obtained data on the possibility of using existing products; development of a modular design that takes into account the possibility of reconfiguration of the component base; object modeling using simplified models. It is worth noting that in the conditions of rapid growth in global energy consumption, a strong and reliable design consisting of standard elements allows you to compensate for energy consumption in various industries of low power production, as well as generate and store energy in areas wh ere there is a need for it.
Keywords: rod system, metal structures, wind power plants, solar modules, batteries, power engineering, modular construction.
IMPLEMENTING DISTRIBUTED GENERATION

Authors: V.V. Okuneva, A.A. Agamirzoev, K.B. Korneev
Abstract: We consider one of the most promising technologies for solving the problem of balancing a system with distributed generation is a virtual substation. It is noted that using the technologies of distributed computing and the «Internet of things», it is possible to implement an effective mechanism for decentralized control of power system elements.
Keywords: electric power, substation, virtualization, automation, distributed generation, «smart» accounting.
TIME REDUCTION TESTS OF RELIABILITY ELECTRICAL EQUIPMENT
Authors: A.Y. Rusin
Abstract: It is noted that improving materials and technologies leads to increased reliability of electrical equipment. It is shown that аt the same time, the time for testing new equipment samples for reliability increases and the cost of carrying them out increases. Research results are given that can reduce the time of testing equipment for reliability.
Keywords: computer simulation, reliability testing of electrical equipment, censored samples, maximum likelihood method, test plan.
ELECTRICAL SPECIFIC CONDUCTIVITY OF THE PRECIPITATION
