Одной из проблем разработки бетонов нового поколения является обеспечение рационального гранулометрического состава смеси цемента и тонкодисперсных добавок для обеспечения плотнейшей упаковки всех частиц цементной системы. В этой связи в работе рассмотрены вопросы оптимизации дисперсной структуры кварцевого наполнителя с учетом его удельной поверхности, концентрации в составе вяжущего и водотвердого отношения.Материалы и методы. В исследованиях применяли портландцемент ЦЕМ I 42,5 Н (ГОСТ 31108–2020) ЗАО «Белгородский цемент» и тонкодисперсный кварц. Образцы на прочность при сжатии испытывали на лабораторном прессе ПГМ-100 МГ4. Гранулометрический состав наполнителей определяли с помощью лазерного дифракционного анализатора размера частиц Analysette 22 NanoTec plus.Результаты. Проведенные исследования позволили определить, что оптимальные дозировки микродисперсного наполнителя тесно связаны с удельной поверхностью и В/Т смеси. Показано, что с ростом дисперсности кварцевого наполнителя наблюдается уменьшение диапазона оптимальных дозировок, который сужается с увеличением водотвердого отношения. Описаны механизмы структурообразования, влияющие на свойства дисперсно-оптимизированных цементных систем. С ростом удельной поверхности наполнителя снижается удельная активность единицы поверхности наполненного вяжущего, что сопровождается снижением количества кристаллизационно-коагуляционных связей между гидратными фазами цемента.Заключение. Полученные экспериментальные данные подтверждают, что для цементного камня из смешанного вяжущего водотвердое отношение является не менее существенным показателем, чем величина концентрации минеральной добавки, поэтому снижение В/Т смешанных цементов является необходимым условием для достижения заданной прочности бетона.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. One of the problems of developing new generation concrete is to ensure the rational granulometric composition of a mixture of cement and fine additives to ensure the densest packing of all particles of the cement system. In this regard, the paper considers the optimization of the dispersed structure of quartz filler, taking into account its specific surface area, concentration in the composition of the binder and water-solid ratio.Materials and methods. In the studies, Portland cement TSEM I 42.5 N (GOST 31108-2020) of ZAO Belgorod Cement and fine quartz were used. The compressive strength samples were tested on a PGM-100 MG4 laboratory press. The granulometric composition of the fillers was determined using Analysette 22 NanoTec plus laser diffraction particle size analyzer.Results. The conducted studies have allowed to determine that the optimal dosages of microdispersion filler are closely related to the specific surface area and the V/T of the mixture. It is shown that with an increase in the dispersion of quartz filler, a decrease in the range of optimal dosages is observed, which narrows with an increase in the water-solid ratio. The mechanisms of structure formation affecting the properties of dispersed-optimized cement systems are described. With the growth of the specific surface of the filler, the specific activity of the unit of the surface of the filled binder decreases, which is accompanied by a decrease in the number of crystallizationcoagulation bonds between the hydrate phases of cement.Conclusion. The experimental data obtained confirm that for a cement stone made of a mixed binder, the watersolid ratio is no less significant than the concentration of a mineral additive, therefore, a decrease in the V/T of mixed cements is a necessary condition for achieving a given strength.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>минеральный наполнитель</kwd><kwd>дисперсность</kwd><kwd>гранулометрия кварцевого наполнителя</kwd><kwd>водотвердое отношение</kwd><kwd>прочность цементного камня</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mineral filler</kwd><kwd>dispersion</kwd><kwd>granulometry of quartz filler</kwd><kwd>water-solid ratio</kwd><kwd>strength of cement stone</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">Калашников В.
