    Heat-resistant concrete based on alumina cement from substandard raw material
    (Springer US, 2019) Vorozhbiyan, R. M.; Shabanova, G. N.; Korogodskaya, A. N.
    Results are provided for development of refractory concrete based on modified alumina cement using chemical industry waste. A quantitative ratio for mixed filler fractions, the effect of production factors on concrete strength, the dependence of its strength properties on form of filler, and solidification conditions are established. It is shown that with respect to physical mechanical and engineering properties the concretes developed is no worse than those existing in the market.With respect to all engineering properties this form of refractory product may be recommended as lining for high-temperature units.

    Effect of hydrodynamic cavitation on the absorption processes occurring in the production of nitric acid
    (Український державний хіміко-технологічний університет, 2019) Vorozhbiian, M. I.; Moroz, N. A.; Vorozhbiyan, R. M.; Mykhailova, E. A.
    The research data on the process of the formation of acid under the conditions of hydrodynamic cavitation are presented in the paper. A change in the absorption properties of activated water exposed to the hydrodynamic cavitation has been established. The physicochemical characteristics of activated water, in particular electrical conductivity, pH value and redox potential, have been studied. It was confirmed that cavitated water can be used in technological processes during 10–15 hours before returning its properties to the initial values. A positive effect of the cavitation on the adsorption capacity of liquid phase in the production of weak nitric acid was established. The use of the cavitation results in an increase in the conversion rate of nitrose gases by 20–30%. The most significant effect is observed in the region of increased concentrations of nitric acid solutions supplied to the absorption column and at increased linear velocities of gaseous phase. The fullscale testing of the cavitated water used for the absorption division of the production of weak nitric acid showed a positive effect which had been revealed during experimental investigations.

    Studying the specific features of the hydration processes of alumina cements based on the compounds of CaO–NiO–Al₂O₃ system
    (Украинский государственный химико-технологический университет, 2018) Shabanova, G. M.; Korogodska, A. M.; Vorozhbiyan, R. M.; Tsapko, N. S.; Khrystych, E. V.; Shutynskyy, O. G.
    The article gives the results of studying hydration processes occurring in cement synthesis using waste products of chemical industry. Cement clinker was synthesized with the relation of initial raw components, calcium-containing water treatment waste and rejected nickel containing catalyst of AZOT Private Joint Stock Company (Severodonetsk, Luhansk Region, Ukraine), equal to 50/50. The obtained samples were studied by Strelkov minor method: normal density, setting time and mechanical strength were determined within 1, 3, 7 and 28 days. The results regarding the setting product were analyzed by differential thermal, X-ray phase analysis, microscopic analysis and electron microscopy; this enables to control the phase relation in the synthesis of a new class of aluminate cements using waste products of chemical industry. The obtained data showed the absence of cubic hydroaluminates which deteriorate the strength. The methods of physicochemical analysis revealed that the phase composition of hydrated alumina cement is represented by calcium hydroaluminate of different basicity, whereas cleavage structure consists of prismatic crystals which give dual coalescence, and this is favorable form to provide matrix self-reinforcement. The developed composition of aluminous nickel-containing cement referred to hydraulic binders. The results of physical-mechanical tests of the synthesized cements indicated that the obtained cements are quick-setting, fast-hardening and high-strength materials.
