В настоящее время нашли широкое распространение сухие строительные смеси на базе гидравлических вяжущих материалов. Применение сухих смесей многогранно и связано в основном с приготовлением растворов и мелкозернистых бетонов. Указанные смеси получают путем регулирования реологических и физико-механических свойств за счет введения модифицирующих добавок и микронаполнителей в виде стеклянных микросфер.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для регулирования свойств смеси на микроскопическом уровне использовались фибровые полимерные и базальтовые волокна, создавая тем самым упрочненную армированную микроструктуру затвердевшего мелкозернистого бетона. Подобраны составы сухих смесей на основе полимерных и базальтовых фибровых волокон с применением суперпластификатора и аппретированных полых стеклянных микросфер марки МС-ВП-А9 в количестве 10 %. Сухая смесь на базе указанного состава с использованием суперпластификаторов, стеклянных микросфер, а также базальтовой или полимерной фибры приготавливается путем перемешивания и измельчения в линейно-индукционном вращателе, который имеет показатель индуктивности переменного поля 0,2 Тл и частоту 50 Гц. Обработка смеси осуществляется в течение 240 с. Полимерные и базальтовые волокна вводились в сухую смесь раздельно, т.е. в каждом составе использовался только один из двух представленных видов волокон.</p></sec><sec><title>Результаты</title><p>Результаты. Активированные в электромагнитном поле сухие смеси затворялись водой в количестве, необходимом для получения растворов равной подвижности. Приготовление раствора производилось в течение 4–5 мин, при этом полученные смеси имели повышенную пластичность и однородность с равным количеством воды затворения в сравнении с контрольными составами без применяемых базальтовых или полимерных волокон.</p></sec><sec><title>Выводы</title><p>Выводы. Анализ экспериментальных данных показал, что оптимальная концентрация суперпластификатора составляет 0,5 % от массы цемента, при которой наблюдается максимальный прирост прочности. Установлено, что оптимальное количество фиброволокна (как базальтового, так и полипропиленового) — 1,4 кг/м³. При этом базальтовое волокно обеспечивает увеличение прочности при сжатии на 28 % и при изгибе на 45 %, а полипропиленовое — на 29 и 42 % соответственно.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Dry building mixes based on hydraulic binders are currently widely used. The use of dry mixes is multifaceted and is mainly associated with the preparation of solutions and fine-grained concrete. These mixes are obtained by regulating rheological and physical-mechanical properties by introducing modifying additives and microfillers in the form of glass microspheres.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Polymer and basalt fibre were used to regulate the properties of the mix at the microscopic level, thereby creating a strengthened reinforced microstructure of hardened fine-grained concrete. The compositions of dry mixes based on polymer and basalt fibre were selected using a superplasticizer and 10 % coated hollow glass microspheres of the MS-VP-A9 brand. A dry mix based on the specified composition with the use of superplasticizers, glass microsphe-res, and basalt or polymer fibre is prepared by mixing and grinding in a linear induction rotator, which has an alternating field inductance of 0.2 T and a frequency of 50 Hz. The mixture is processed for 240 seconds. Polymer and basalt fibres were introduced into the dry mix separately, i.e. only one of the two presented types of fibres was used in each composition.</p></sec><sec><title>Results</title><p>Results. Dry mixes activated in an electromagnetic field were mixed with water in the amount necessary to obtain solutions of equal mobility. The solution was prepared for 4–5 minutes, while the resulting mixtures had increased plasticity and homogeneity with an equal amount of mixing water, in comparison with the control compositions, without the use of basalt or polymer fibres.</p></sec><sec><title>Conclusions</title><p>Conclusions. The influence of the type and quantity of fibre on the physical and mechanical properties of fine-grained concrete obtained on the basis of dry building mixtures activated by electromagnetic treatment was determined.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фиброволокна</kwd><kwd>сухие строительные смеси</kwd><kwd>электромагнитная активация</kwd><kwd>стеклянные микросферы</kwd><kwd>суперпластификатор</kwd><kwd>мелкозернистый бетон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fibre</kwd><kwd>dry building mixes</kwd><kwd>electromagnetic activation</kwd><kwd>glass microspheres</kwd><kwd>superplasticizer</kwd><kwd>fine-grained concrete</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kanaan D.M., Soliman A.M.
