Применение минеральных добавок (МД) в составах цементных бетонов дает возможность снижать расход портландцемента (ПЦ), что при возрастающих темпах строительства уменьшает негативное воздействие на экологию при его производстве. Однако высокая стоимость и территориальная ограниченность производства наиболее эффективных модификаторов (микрокремнезем, метакаолин) не позволяют в полном объеме удовлетворить возрастающий на них спрос. Разработка МД из широко распространенного сырья поможет решить проблему дефицита наиболее распространенных добавок, а также снизить объемы потребления ПЦ. Механизм твердения ПЦ с широко распространенными МД достаточно подробно изучен. При этом работы, описывающие процессы гидратации цементного вяжущего, модифицированного МД на основе термоактивированных глинистых и карбонатных пород, практически отсутствуют.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В качестве МД использованы: термоактивированная глина (Никитское месторождение, г. Саранск, Республика Мордовия), доломит (с. Ельники, Республика Мордовия), термоактивированная смесь глины и известняка (с. Атемар, Республика Мордовия). С применением метода рентгенофазового анализа исследованы механизмы действия указанных МД на процессы гидратации.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что применение рассматриваемых МД позволяет повысить степень гидратации ПЦ и направлено изменять фазовый состав цементного камня.</p></sec><sec><title>Выводы</title><p>Выводы. Полученные данные свидетельствуют о перспективности и актуальности направления по разработке бетонов с модифицирующими добавками на основе термоактивированных полиминеральных глин и карбонатных пород, что позволяет расширить номенклатуру выпускаемых на сегодняшний день модифицированных цементных композитов за счет более полного использования местной минеральной сырьевой базы.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The use of mineral additives in cement concrete compositions makes it possible to reduce the consumption of Portland cement, which, with increasing construction rates, reduces the negative impact on the environment during its production. However, the high cost and territorial limitation of the production of the most effective modifiers (microsilica, metakaolin) do not allow to satisfy the growing demand for them. The development of mineral additives from widely used raw materials will help solve the problem of the deficit of the most common additives, as well as to reduce the consumption of Portland cement. The mechanism of hardening of Portland cement with widespread mineral additives was studied in sufficient detail. At the same time, there are practically no works describing the processes of hydration of cement binder modified with mineral additives based on thermally activated clay and carbonate rocks.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The following mineral additives were used: thermally activated clay (Nikitskoye deposit, Saransk, Republic of Mordovia), dolomite (Elniki village, Republic of Mordovia), thermally activated mixture of clay and limestone (Atemar village, Republic of Mordovia). Using the method of X-ray phase analysis, the mechanisms of action of these mineral additives on hydration processes are considered.</p></sec><sec><title>Results</title><p>Results. It was established that the use of these mineral additives makes it possible to increase the degree of hydration of Portland cement and change the phase composition of the cement stone in a targeted manner.</p></sec><sec><title>Conclusions</title><p>Conclusions. The data obtained indicate the prospects and relevance of the direction for the development of concretes with modifying additives based on thermally activated polymineral clays and carbonate rocks, which makes it possible to expand the range of modified cement composites produced today due to more complete use of the local mineral resource base.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цементный камень</kwd><kwd>полиминеральная глина</kwd><kwd>доломит</kwd><kwd>известняк</kwd><kwd>пластифицирующая добавка</kwd><kwd>фазовый состав</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cement stone</kwd><kwd>polymineral clay</kwd><kwd>dolomite</kwd><kwd>limestone</kwd><kwd>plasticizing additive</kwd><kwd>phase composition</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">Хозин В.Г., Хохряков О.В., Сибгатуллин И.Р. «Карбонатные» цементы низкой водопотребности.
