Детальное описание гидратационных процессов твердения включает в себя проблемы растворения клинкеров, диффузионные процессы, поверхностные явления на зародышах новых фаз, количественный состав твердого вещества и рост продуктов гидратации, пористой структуры, влаги в зависимости от времени твердения и водоцементного отношения. Термодинамическое моделирование гидратации портландцементов в рамках модели Lothenbach позволяет осуществить в значительной мере решение указанных проблем. В программном комплексе GEMs оценивается в равновесных условиях количественное содержание как исходного клинкера, так и продуктов гидратации (цементный камень, портландит и т. д.) в течение длительного времени. В статье представлены результаты моделирования содержания фаз в процессе гидратации портландцемента в программе GEMs в рамках модели B. Lothenbach при отсутствии минеральных добавок calcite, lime, angydrite, gypsum, hemyhydrate, K 2 SO 4 . Водоцементное отношение было выбрано равным 0,3; 0,4 и 0,5. Установлено, что к конечным доминирующим продуктам относятся гель CSHQ сложного состава, portlandite, нерастворимые клинкерные минералы, а также hydrogarnet, monosulfate, влага, распределенная в пористом пространстве, эттрингит отсуствует. Определено, что доля пористого пространства возрастает c увеличением водосодержания и даже после 1250 дней твердения вклад нерастворимых клинкеров составляет 20–25 г среди 150 г гидратированного портландцемента.</p></abstract><trans-abstract xml:lang="en"/><kwd-group xml:lang="ru"><kwd>термодинамическое моделирование</kwd><kwd>гидратация портландцемента</kwd><kwd>водоцементное отношение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thermodynamic modeling</kwd><kwd>Portland cement hydration</kwd><kwd>water/cement ratio</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации (тема № FEMN-2020-0004)</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the state task of the Ministry of Science and Higher Education. of the Russian Federation (subject No. FEMN-2020-0004)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lothenbach B., Winnerfeld F.
