Различными авторами исследованы математические модели теплового режима объемной строительной конструкции. Математическая модель уравнений теплового баланса в бетонной конструкции, коэффициент теплопроводности, зависимости уравнений теплового баланса в бетонной конструкции и примыкании, объемная теплопроводность соответственно в возведенном фрагменте и ранее возведенной части стены реализована на ЭВМ. В статье рассмотрены процессы набора прочности цементом и бетоном при раннем замерзании бетона. Предыдущими исследованиями разных авторов установлено, что при увеличении времени набора критической прочности затраты электроэнергии снижаются на 25–50% за счет использования тепловой инерции конструкции. Выявлена скорость охлаждения монолитных конструкций при отрицательных температурах. Показана химия процессов твердения цемента при раннем замерзании. Термодинамическими расчетами установлены пределы отрицательных температур, при которых прекращается набор прочности бетоном, но при действии повторных положительных температур процесс гидратации цемента возобновляется и бетон продолжает твердеть. Алюминиевые минералы портландцементного клинкера обычно первыми гидратируются при затвердевании цемента водой, а в присутствии гипса образуют гидросульфоалюминат кальция. Это соединение очень непрочно и разрушается при механическом воздействии (повторной вибрации) и со временем даже при нормальных температурах. В статье рассмотрен зарубежный опыт зимнего бетонирования и предпочтительные методы работ в этом случае.</p></abstract><trans-abstract xml:lang="en"><p>This article considers energy-saving technologies for winter concreting of building structures and constructions. Various authors have studied mathematical models of the thermal regime of a three-dimensional building structure. The mathematical model of the heat balance equations in the concrete structure, the thermal conductivity coefficient, the dependences of the heat balance equations in the concrete structure and the junction, the thermal conductivity coefficient, the volumetric thermal conductivity, respectively, in the erected fragment and the previously erected part of the wall was implemented on a computer. The article considers the processes of cement and concrete strength gain during early freezing of concrete. In previous studies by various authors, it was found that with an increase in the time for gaining critical strength, the cost of electricity is reduced by 25-50%, due to the use of thermal inertia of the structure. The rate of cooling of monolithic structures at negative temperatures is revealed. The chemistry of cement hardening processes during early freezing is shown. Thermodynamic calculations set the limits of negative temperatures at which concrete strength curing stops, but under the action of repeated positive temperatures, the cement hydration process resumes and concrete continues to harden. The aluminum minerals of Portland cement clinker are usually the first to hydrate when the cement hardens with water, and in the presence of gypsum they form calcium hydrosulfoaluminate. This connection is very fragile and is destroyed by mechanical stress (repeated vibration) and over time even at normal temperatures. The article reviews the foreign experience of winter concreting and the preferred methods of work in this case.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>зимнее бетонирование</kwd><kwd>массивность конструкции</kwd><kwd>гидратации минералов портландцемента</kwd><kwd>добавки в зимний бетон</kwd><kwd>электроразогрев бетонной смеси</kwd><kwd>бетонирование в «тепляках»</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Winter concreting</kwd><kwd>massiveness of the structure</kwd><kwd>hydration of Portland cement minerals</kwd><kwd>additives in winter concrete</kwd><kwd>electric heating of the concrete mix</kwd><kwd>concreting in "greenhouses"</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">Alexandrovsky S.V.
