  • Determination of phase composition of sealing coating based on APC
           (aluminophosphate compounds)

    • Authors: V. I. Bolshakov, O. B. Zahorodniy, S. I. Veselova
      Pages: 10 - 19
      Abstract: Goal. To investigate the phase composition of the obtained sealing coatings based on aluminophosphate compound (APC) and the impact of temperature rise on it. Methods. Qualitative X-ray phase analysis (XRPA) and differential thermal analysis (DTA) are used as the methods of research. Roentgenograms for structural analysis were obtained on a DRON-4-07 using filtered copper radiation in the secondary beam. Registration and initial processing of diffraction patterns was performed using the software package PDOS with the output of the diffraction patterns on the screen. Using the "loupe" option allowed to identify weak interference lines, which increased the accuracy of the method of qualitative XRPA. The thermograms for DTA received on the device type Termoskan-2. The results. It is revealed that base of coating is X-ray amorphous phase. There are following crystalline phases: Al, AlPO4, Al (PO3) 3, BN found in the coating. It is revealed that annealing doesn’t make a significant influence on the phase composition of the crystalline phases and the coating doesn’t lose properties after annealing during repeated thermal stress. Scientific novelty. The phase composition of the proposed sealing coatings based on APC and produced by plasma spraying, and the effect of annealing on the phase composition of the coating are investigated. The reaction of synthesis of primary material forming on the basis of APC for coating is offered. Practical significance. The results can be used in aviation technology in the development of gas turbine engines (GTE) and the design of the compressors. The sealing coating may be used to improve the reliability of the compressor and to increase the efficiency ratio of turbine engine. During the operation the compressor’s blades touch the sealing coating of compressor’s stator and grooves it without causing locking and destruction of the rotor. Therefore, the development of new sealing coating compositions that provide reliable operation of the GTE compressor, and determination of their properties and structure, are very important.

  • Impact of nanomodifiers on mechanical and physical properties of gypsum
           binders

    • Authors: V. M. Derevianko, H. M. Hryshko
      Pages: 62 - 67
      Abstract: Problem statement. In the next 10 years, more than 90 % of materials will be replaced with new materials – nanocomposites [1]. The nanocomponents application will allow manufacture of high-strength materials with reduced production cost and will ensure demand for products [2]. Researches aimed to determination of carbon nanotube type nanomodifier concentration impact on the physical and mechanical properties of gypsum binders are important today and must result in creation of competitive strong nano-materials. Purpose. Research of carbon nanotube (CNT) type nanomodifier concentration impact on the physical and mechanical properties of gypsum binders. Conclusion. Sample microstructure analysis revealed that the non-modified gypsum sample structure is dominated by prismatic and lamellar crystals randomly distributed throughout the matrix volume. In this case, loose structure with increased porosity is formed, which results in sample mechanical strength reduction. In the CNT-modified gypsum matrix, well-ordered and homogeneous structure is formed with larger needle-shaped crystals, which results in the phase-contacting area increase, porosity reduction and thus the physical and mechanical characteristics improvement. It is experimentally proved that at the identical nano-modifier content in the gypsum matrix (0.035 %), maximum compression strength gain is achieved with the use of CNT and makes 28‑ 30 %. At the use of initial carbon nanotubes, increase in strength at the same nano-modifier content makes 13‑15 %. The Ca2+ ions interaction with the graphene-like carbon surface was investigated by the DFT method. Capability is demonstrated of the covalent calcium bonding with the hexagonal carbon surface cell as a result of overlap of Ca2+ valence 3p orbitals and carbon 2р orbitals.

  • Stress-strain state of masonry of chimney trunks from dead load, wind load
           and temperature effect

    • Authors: Yu. M. Yarovoj, O. Ye. Lukashenko, E. O. Perepelica
      Pages: 78 - 84
      Abstract: Formulation of the problem. Nowadays there are more than 3000 masonry chimneys in Ukraine. The life of most chimneys is more then 20 years, about 20 % of the chimneys are operated for more than 50 years. Inspection of the technical condition of the chimneys, evaluation of their load-carrying capacity and design of recommendations for further work of chimneys is an actual research task. There are no actual normative documents about calculation and design of masonry and reinforced concrete chimneys in Ukraine. In reference literature and normative documents, the design scheme of the chimney trunk is adopted in the form of a cantilever beam. In the calculation it is recommended to take into account the longitudinal-transverse bending from the action of the wind load and its own weight, as well as the roll of the foundation. Strength test of the trunk is performed separately for horizontal sections and for vertical sections. For horizontal sections it is performed for longitudinal force and bending moment from its own weight and wind load, for vertical sections – for temperature forces after the temperature drop along the thickness of the barrel wall. This approach doesn't fully reflect the real work of the masonry, which is in a complicated state of stress. Purpose. To perform a comparative calculation of the various trunks of masonry chimney, analyze the factors affecting the stress-strain state of the masonry trunks. Conclusions. It is proposed carry and calculation of the masonry trunks for the temperature impact in elastic stage with regard to join work masonry and clamping rings, taking into account not only the tangential, but also the longitudinal temperature stresses and analyze the work of the masonry in the plane stress state. Proposed calculation makes it possible to determine the moment of formation of force and temperature cracks in the masonry. It is necessary to clarify the stress-strain state and criteria of the trunks strength of masonry chimney under a two-dimensional stress state with the help of numerical and experimental models.

  • Modified gypsum binder

    • Authors: N. V. Kondrateva, L. V. Moroz, V. Yu. Moroz, A. I. Begun
      Pages: 93 - 100
      Abstract: Statement of the problem. A disadvantage of the gypsum binder is the limited water resistance of products that historically led to the use of gypsum products mostly for internal construction and finishing works. To regulate the process of hydration and structure formation of the use of chemical additives that are introduced with the mixing water or in the production of the binder. As a rule, substances that increase the solubility of the gypsum binder referred to as the hardening accelerator, and substances which retard the solubility of the inhibitors of hardening of the mixture. Most accelerators and retarders hardening affect adversely on the final strength of the mixture. More effective impact on gypsum binder additives have plasticizers. The purpose of the article. Getting gypsum binder modified with the aim of improving its water resistance and improvement of some technological factors (the time of hardening, water gypsum ratio, etc.) would reduce its shortcomings and expand the scope of application of the binder. Conclusion. The result of the research reviewed changes in the basic properties of the gypsum binder with the introduction of additives, plasticizers, and selected the most effective supplements to significantly reduce water gypsum ratio, to improve strength properties and to obtain gypsum binder more dense structure.

The complex of repair and restoration works should be divided into three stages (preparatory, main and final). A significant period of production takes the preparatory stage (41 %). Performing repair and restoration works by the flow method allows to maximize the use of labor resources and a set of construction machines. The use of scaffolds and a modern formwork system for the re-establishment of the central vault allowed to reduce the labor intensity of work, which in turn led to a reduction in the number of employed workers and an increase the pace of work.
