Грунтоцементный композит — тщательно перемешанная смесь грунта, цемента и воды — играет важнейшую роль в строительстве различных объектов гражданской инфраструктуры, таких как фундаменты мостов, тоннелей, насыпи автомобильных дорог, фундаменты сооружений портов и гаваней и др. Несмотря на эффективность, традиционные цементные составы с высоким содержанием цемента вызывают серьезные экологические проблемы, что заставляет искать альтернативные материалы, способные обеспечить экологическую устойчивость строительства.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Изучено влияние молотого гранулированного доменного шлака на технические характеристики грунтово-цементных смесей. Использовалась сканирующая электронная микроскопия для изучения микроструктуры грунтово-цементного композита, выявления расположения частиц, структуры пор и распределения цементирующих материалов.</p></sec><sec><title>Результаты</title><p>Результаты. Глинистый грунт смешивается с 20 % портландцемента и молотым гранулированным доменным шлаком в разных пропорциях (20, 25 и 30 % по весу цемента) в качестве замены портландцемента. Композитная смесь несколько раз подвергается испытаниям прочности на одноосное сжатие недренированной смеси грунта, цемента и молотого гранулированного доменного шлака на разных этапах твердения (7, 14 и 28 дней).</p></sec><sec><title>Выводы</title><p>Выводы. Результаты показывают, что состав, содержащий глинистый грунт и 20 % цемента, замененного на 20 % молотого гранулированного доменного шлака, обладает максимальной прочностью по сравнению со всеми другими испытанными составами со значительным увеличением на 24 % по сравнению с обычной грунтоцементной смесью на основе глинистого грунта.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. A soil-cement composite, comprising a thoroughly blended mix of soil, cement, and water, has played a crucial role in the construction of various civil infrastructures like bridge foundations, tunnels, highway embankments, foundations for port and harbour structures, and many more. Though efficient, traditional high-cement formulations pose severe environmental concerns, leading to the exploration of alternative materials that can bring sustainability to construction practices.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. This study focuses on utilizing “Ground-Granulated Blast-Furnace Slag” (GGBS) to explore its impact on the engineering characteristics of soil-cement mixtures. In this investigation, clay soil is blended with 20 % of OPC and varying proportions of GGBS (20, 25 and 30 % by weight of cement) as a replacement for OPC.</p></sec><sec><title>Results</title><p>Results. The composite mixture is subjected to several Unconfined Compressive Strength (UCS) tests to assess the undrained shear strength of soil-cement-GGBS mixtures at distinct curing intervals (7, 14, and 28 days). Field emission scanning electron microscopy (FE-SEM) is also employed to examine the microstructure of the soil-cement composite, revealing the arrangement of particles, pore structures, and the distribution of cementitious materials.</p></sec><sec><title>Conclusions</title><p>Conclusions. The results show that the composition having clay soil and 20 % cement, replaced with 20 % GGBS, yields maximum strength among all tested compositions with a significant increase of 24 % compared to the conventional soil-cement mixture of clay soil and 20 % cement only.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>грунт – цемент</kwd><kwd>молотый гранулированный доменный шлак</kwd><kwd>обычный портландцемент</kwd><kwd>прочность на одноосное сжатие</kwd><kwd>смесь грунт – цемент – молотый гранулированный доменный шлак</kwd><kwd>сканирующая электронная микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>soil – cement</kwd><kwd>ground-granulated blast-furnace slag (GGBS)</kwd><kwd>ordinary portland cement (OPC)</kwd><kwd>unconfined compressive strength (UCS)</kwd><kwd>soil – cement – GGBS mixture</kwd><kwd>scanning electron microscopy (SEM)</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы выражают искреннюю благодарность кафедре гражданского строительства Индийского технологического института в Индоре за обеспечение необходимых условий для проведения данного исследования.
