На практике требуется получение смесей равной удобоукладываемости, оцениваемой стандартными техническими показателями (осадка конуса, расплыв и др.), но в то же время с различными реологическими характеристиками. Эффективно снижают предел текучести и вязкость добавки-разжижители, однако влияние минеральных добавок в комбинации с органическими ПАВ на реологические показатели цементных дисперсий мало изучено. Работа посвящена исследованию данного вопроса.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Использовали тонкодисперсные кварц (Sуд=340 м2/кг) и мрамор (Sуд=320 м2/кг), полученные помолом в лабораторной мельнице; вяжущее ЦЕМ I 42,5 Н ЗАО «Осколцемент» (τн.схв=230 мин; НГ=26%, C3S=61,59%, C2S=14,2%, C3A=6,83%, C4AF=3,73%); суперпластификатор «Полипласт СП-1», гиперпластификатор Sunbo 2021. Реологические показатели цементных дисперсий определяли при малых градиентах скорости сдвига έ до 25 с-1, что позволяет обеспечить подобие потока в лабораторных и в реальных условиях.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что чистые и смешанные цементные дисперсии без добавок-разжижителей являются реологически сложными телами с наибольшим предельным напряжением сдвига и пластической вязкостью. Минеральные модификаторы в комбинации с пластифицирующими добавками эффективно снижают пластическую вязкость и напряжение сдвига, их течение переходит в режим ньютоновской жидкости с вязкостью, не зависящей от градиента скорости сдвига. Реологические показатели бездобавочных смешанных цементных дисперсий зависели от вида минерального наполнителя. При этом с вводом добавок-разжижителей преобладающее влияние на реологические показатели оказывают дозировки и химическая основа добавок.</p></sec><sec><title>Заключение</title><p>Заключение. Смешанные цементно-мраморные и цементно-кварцевые дисперсии с вводом добавок разжижающего действия характеризуются более высокой текучестью, чем чисто цементные. Введение пластифицирующих добавок при определенных дозировках позволяет полностью снимать нелинейность, а ввод минеральных наполнителей усиливает эффективность действия ПАВ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. In practice, it is required to obtain mixtures both of equal workability, estimated by standard technical indicators (cone sediment, spreading, etc.) and of diﬀerent rheological characteristics. Diluent additives eﬀectively reduce the yield strength and viscosity, however, the eﬀect of mineral additives in combination with organic surfactants on the rheological parameters of cement dispersions has been poorly studied. The paper is devoted to the study of this issue.</p></sec><sec><title>Research methods</title><p>Research methods. Finely dispersed quartz (Sud=340 m2/kg) and marble (Sud=320 m2/kg) obtained by grinding in a laboratory mill were used; binder CEM I 42.5 H of Oskolcement CJSC (tn.cw=230 min; НГ=26 %, C3S=61,59 %, C2S=14,2 %, C3A=6,83 %, C4AF=3,73 %); superplasticizer Polyplast SP-1, hyperplasticizer Sunbo 2021. Rheological parameters of cement dispersions were determined at low shear rate gradients έ up to 25 sec-1, which makes it possible to ensure the similarity of ﬂow in laboratory and real conditions.</p></sec><sec><title>Results</title><p>Results. It has been established that pure and mixed cement dispersions without diluent additives are rheologically complex bodies with the highest shear stress and plastic viscosity. Mineral modiﬁers in combination with plasticizing additives eﬀectively reduce plastic viscosity and shear stress, and their ﬂow transitions to the Newtonian ﬂuid regime with a viscosity independent of the shear rate gradient. Rheological parameters without additional mixed cement dispersions depended on the type of mineral ﬁller. At the same time, with the introduction of diluent additives, dosages and the chemical base of additives have a predominant eﬀect on rheological parameters.</p></sec><sec><title>Conclusion</title><p>Conclusion. Mixed cement-marble and cement-quartz dispersions with the introduction of diluting additives are characterized by higher ﬂuidity than cement dispersions. The introduction of plasticizing additives at certain dosages makes it possible to completely remove non-linearity, and the use of mineral ﬁllers enhances the eﬀectiveness of surfactants.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цементные системы</kwd><kwd>минеральный наполнитель</kwd><kwd>пластификатор</kwd><kwd>предел текучести</kwd><kwd>пластическая вязкость</kwd><kwd>реологические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cement systems</kwd><kwd>mineral filler</kwd><kwd>plasticizer</kwd><kwd>yield strength</kwd><kwd>plastic viscosity</kwd><kwd>rheological properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет средств гранта Российского научного фонда (проект №25-19-00866).
