Published: August 2020

Abstract
The article considers architectural, city planning, engineering and technological innovations in the building industry that were carried out in Kharkiv in the 1960-1980s and led to profound changes in the social organization of city life. During these years, Kharkiv confirmed its reputation of the scientific and technical capital of Ukraine in the field of architecture and city planning. The most important innovations that were worked out in Kharkiv as in one of the largest cities include the microdistrict system, a stepped public service system, and the focusing method in city planning. It was also innovative to create standard series of residential buildings for mass industrialized development at Kharkivproekt and Ukrmistobudproekt institutes. Technological innovations were created in high-tech house-building plants, organizational and managerial ones – in managerial combines capable of coordinating the entire project and investment cycle. Mass industrial residential development in the mid-1980s allowed liquidation of the housing crisis in Kharkiv. However, this period gave rise to a number of problems in functioning and maintenance of the huge residential areas created at that time. Analysis and objective assessment of the achievements and mistakes of the era of mass industrial construction is a task of current interest for Ukrainian architectural science.

Published: August 2020

Abstract
Modern trends in the development of the global cement industry are to reduce the energy intensity of production and reduce the environmental burden on the environment. These goals can be achieved by using fuel-containing man-made waste in place of natural raw materials and fuel. Great decrease of fuel costs by 20-40 % when making Portland cement is shown to be achieved by combining calcination of both Portland cement clinker and carbonate-silica mix in one heat and technological cycle to get cements with low-temperature calcination. Extra heat effect is achieved by adding combustible industrial wastes, like ashes from power plants or coal waste, to the raw mix to get cements with low-temperature calcination. Further modification of lime-silica cements obtained by Portland cement clinker within 20-40 % range by weights is shown to get mixed product with strength indices in sand mortar corresponding to 0,6-0,8 grade strength of original Portland cement. Combined method for making two kinds of binders is shown to reduce carbon dioxide by 22-60 % calculated as the final modified product as compared with traditional making of Portland cement clinker. When substituting 50 % of clinker part by cements with low temperature calcination with certain composition, grade strength of the mixed product is similar to Portland cement indicators.

Published: August 2020

Abstract
The foundations of wind farms are massive structures that require temperature control of concrete hardening during their construction. This is due to the need to ensure crack resistance and specific operating conditions of engineering networks located in the body of the structure. The work describes a comprehensive study of the foundations construction on the Zaporizhzhya wind farm. The study included calorimetric analysis using adiabatic calorimetry and on-site temperature monitoring of the object using a continuous temperature measurement system. Laboratory studies allowed verify the composition of concrete proposed by the concrete manufacturer and develop recommendations for concreting. The data obtained showed that the hardening conditions approach adiabatic ones with a foundation slab thickness of more than 2.5 m. This leads to a temperature gradient of more than 25 ° C between the internal and external parts of the structure. The adopted recipe and technological solutions have ensured the achievement of acceptable conditions for the foundation slab construction in the winter.

Published: August 2020

Abstract
The facing material was developed for the purpose of shielding man-made electromagnetic fields in production working and domestic conditions. The facing material was designed on the base of latex and fine iron ore concentrate as filler. The experimental data on shielding of electromagnetic fields of ultrahigh frequencies and magnetic field of industrial frequency were obtained for different material thicknesses and concentration of screening particles. The significant increase of the shielding coefficients was established and explained by the manifestation of the percolation effect - the increase of the material conductivity at the critical concentration of the conductive component. The calculation apparatus for determining the dependence on the shielding properties of the material on the concentration of shielding substance was proposed. The method of the screening substance critical concentration calculation is shown to enable designing materials of lower thickness, weight and self-cost.

Published: August 2020

Abstract
In the article effectiveness of the use of fillers to improve the physical and mechanical properties of the coating varied depending on the average size of the filler particles and crystalline shape was studied. According to the indicators of impact strength to back impact and bending strength of the coating, the most effective is the use of microsilica with an average size of 2.9 μm. As the average filler size increases, the gloss and impact strength of the coating reduce. To increase the bending strength of the coating, it is advisable to use fillers in the form of wollastonite, which is characterized by a fibrous crystal shape, which improves the physical and mechanical properties of the coating and prevents cracking, acting as a reinforcing agent. In addition, the analysis of the obtained study results shows that the use of the studied Ukrainian-made fillers in the powder paint composition promotes obtaining a covering with adjustable physical and mechanical characteristics.

Published: August 2020

Abstract
The methodic of evaluation of the innerdrain hydraulic of the water flow along the length of the drains of the ranney drainage (water uptake) on summary inflow to them is developed. The methodic is based on the mathematical models which allow more fully to take into account the complex real flow character and the hydraulic conditions in the zone of the influence ranney water intakes and drainages. The different cases of solution of joint problem of flow in aquifer and in the drains-rays are considered and presented as the system of the analytic dependences. Obtained results showed that the inflow to drain-ray is distributed uneven along its length and the main inflow is formed in the first half of the drain-ray. Therefore, in some cases the influence of innerdrain hydraulic should be taken into account when calculating the parameters of drainage and evaluation of their operation.

Published: August 2020

Abstract
The most common to date are multifunctional sports complexes. Their multifunctionality, in addition to competing in various sports, provides the opportunity for a variety of grand events, including corporate brand companies, concerts of the most popular music groups and performers, as well as meetings and conferences of religious denominations. When designing and reconstruction stadiums, it is important to anticipate activities and lay out ideas that may be implemented in the future. Although multifunctionality is ensured by the ability to organize and conduct various public events, the stadium must retain a number of features that will help it to fulfill its essential function of generating appropriate revenue. For modern sports facilities it is necessary to perform two main functions - the city-forming and the function of the development of the multifunctional urban environment. Today, work is underway on the reconstruction of the Kiev stadium of the CSC AF of Ukraine, located on Povitroflotsky Prospekt. The reconstructed site is located in the city’s central planning zone, in the northern part of Solomenskiy administrative district on Povitroflotsky prospect, 6. The capacity of the facility is 20,000 seats. The updated CSK AFU Stadium will be a football and athletic arena. The project meets modern European and world standards. This stadium, located in the center of the capital, together with a spare (warm-up) and separate thrower stadium, as well as a special athletics arena, can become the main base for the preparation of the national athletics team of Ukraine, the athletes of Kiev, and the place of qualitative holding championships in athletics of Ukraine.
