   <abstract xml:lang="ru">
    <p>Исследование посвящено изучению структуры и свойств гипсозольных композиций, которые представляют собой экологически чистые строительные материалы. Для их изготовления используются смеси, включающие помимо гипсового вяжущего модификатор на основе золы сухого удаления с высоким содержанием оксида кальция (свободной извести). Именно эта особенность их химического состава препятствует широкому применению таких зол в строительной индустрии. Свободный оксид кальция в достаточно большом объеме (свыше 5 %) является причиной протекания деструктивных процессов в затвердевшем гипсовом камне. Поэтому основной целью данного исследования являлось изучение влияния свободного оксида кальция в составе высококальциевых зол на процесс синтеза гипсовой высокопрочной композиции, поскольку это позволит эффективно утилизировать многотоннажный технологический отход. &#13;
В статье представлены результаты экспериментального исследования, включающего анализ свойств высокопрочных композиций, полученных варьированием золы в составе композиций на основе гипсового вяжущего α-модификации. Результаты исследования показали, что применение золы с высоким содержанием «свободной извести» в качестве активного компонента в составе композиции, позволяет достичь прочности более 95 МПа.  что почти в 3 раза превышает прочность чистого гипсового камня. Введение высокодисперсного зольного компонента обуславливает повышение свойств композиции за счет синергии механического и физико-химического воздействия на ее структуру и свойства модифицированного камня. Общую оценку структурных и физико-механических свойств возможно сформировать по результатам исследований основных характеристик модифицированного камня в сопоставлении с данными химического и микроструктурного анализа. Кроме того, исследование порового пространства камня подтвердило высокую эффективность введения золы сухого удаления в составе модифицированной высокопрочной гипсовой композиции.</p>

    <p>This study examines the structure and properties of gypsum ash composites, which are environmentally friendly building materials. They are manufactured using mixtures containing, in addition to gypsum binder, a modifier based on dry-stripped fly ash with a high calcium oxide content (free lime). This particular chemical composition hinders the widespread use of such ash in the construction industry. Free calcium oxide, in large quantities (over 5%), is the cause of destructive processes in hardened gypsum. Therefore, the primary objective of this study was to investigate the influence of free calcium oxide in high-calcium fly ash on the synthesis of high-strength gypsum composites, as this will enable the efficient disposal of large-scale industrial waste. &#13;
This article presents the results of an experimental study analyzing the properties of high-strength composites obtained by varying the ash content in composites based on an α-modified gypsum binder. The study demonstrated that the use of ash with a high content of &quot;free lime&quot; as an active component in the composite allows for a strength of over 95 MPa, which is almost three times greater than that of pure gypsum. The introduction of a highly dispersed ash component enhances the composite's properties due to the synergy of mechanical and physicochemical effects on its structure and the properties of the modified gypsum. A general assessment of the structural and physicomechanical properties can be formed based on the results of studies of the modified gypsum's key characteristics in comparison with chemical and microstructural analysis data. Furthermore, a study of the pore space of the gypsum confirmed the high efficiency of introducing dry-stretched ash into the modified high-strength gypsum composite.</p>
