    Processes of structure formation and neoformation of basalt fiber in an alkaline environment
    (IOP, 2020) Berdnyk, O. Yu.; Lastivka, O. V.; Maystrenko, A. A.; Amelina, N. O.
    Several approaches can be used to determine the effect of an alkaline environment on glass materials (basalt fibers). One of the most common approaches for the determination of the alkali resistance of a substance is to measure the relative mass loss after the interaction of the object of research with the alkaline environment. According to the practice guidelines, the approach involves determining the alkali resistance of a glass by measuring the mass loss per unit area of the glass under test after boiling it in an alkaline solution. But the disadvantage of this approach is it can’t be applied to basalt or another multicomponent fiberglass as it doesn’t introduce different speeds of fiber dissolution.

    Production of modified basalt fibre for heat-insulating products manufacturing
    (IOP Publishing, 2019) Gots, V. I.; Berdnyk, O.Y.; Rogozina, N. O.; Maystrenko, А. А.
    As a result of the research flexible heat-insulating materials were developed based on basalt fiber with increased effectiveness, which can be achieved due to directed fiber microstructure forming through fusion modification. It is known that chemical composition of initial fusion not identically influences on physical and chemical and mechanical properties of basaltic fibres. Structural descriptions of fusion and basaltic fibre got from him appear main factors the nearer, than high speed of cooling. This index mainly depends on such constituents: а) ambient temperatures; b) coefficient of heat conducting; c) heat conducting of fusion; d) areas of surface. By researches influence of temperature of basaltic fusion was shown on the structure of fibres. Structural characteristics of the basalt fiber (number of active zones, coefficient of its distribution on the basalt fiber surface, as well as a correlation of three groups of active zones) depend on rheological properties of basal fusion, speed of drawing through the die plate and cooling speed.

    Модифікація структури стабілізованого базальтового волокна
    (Харків: ХНУБА, 2020, 2020-05) Гоц, В. І.; Пальчик, П. П.; Омельчук, В. П.; Тимошенко, С. А.
    Розвиток будівельного виробництва, підвищення вимог до конструктивних і теплофізичних характеристик споруд вимагає створення матеріалів, які по своїм властивостям повинні значно перевищувати існуючи.
