The use of innovative technologies, minimum construction time, durability, reliability, the ability to perform work in various climatic conditions, architectural individuality contribute to the development of monolithic construction. Concrete and reinforced concrete are the main materials of modern construction. The quality of structures depends not only on the composition of concrete, the amount of portland cement, the chemical additives used, the water-cement ratio, the quality of fillers, etc., but also significantly on the heat and humidity regime of concrete holding. To ensure the necessary temperature conditions for hardening and strength gain of concrete, various methods of heating structures are used. One of the methods of concrete care is thermal processing during the hardening period and the acquisition of critical or design strength. The aim of the study is to improve the technology of erection of monolithic concrete and reinforced concrete structures using thermal processing of concrete by means of infrared radiation. The technology of thermal processing of the laid and compacted concrete mixture using infrared heating and a two-chamber transparent shelter for infrared rays has been developed. The obtained results permit us to provide conditions for the normal course of the chemical reaction of hydration, hardening and strength gain. This allows successfully solve the problems of concreting in the erection of buildings and structures made of monolithic concrete and reinforced concrete.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">В настоящее время все большую актуальность приобретает строительство зданий из монолитного бетона и железобетона. Применение инновационных технологий, минимальные сроки строительства, долговечность, надежность, возможность выполнения работ в различных климатических условиях, архитектурная индивидуальность способствуют развитию монолитного строительства. Бетон и железобетон являются основными материалами современного строительства. Качество конструкций зависит не только от состава бетона, количества портландцемента, применяемых химических добавок, водоцементного отношения, качества наполнителей и др., но и существенным образом от тепловлажностного режима выдерживания бетона. Для обеспечения необходимых температурных условий твердения и набора прочности бетона используют различные методы прогрева конструкций. Одним из них является тепловая обработка в период твердения и приобретения критической или проектной прочности. Цель исследования - совершенствование технологии возведения монолитных бетонных и железобетонных конструкций с использованием тепловой обработки бетона посредством инфракрасного излучения. Разработана технология тепловой обработки уложенной и уплотненной бетонной смеси с использованием инфракрасного обогрева и двухкамерного прозрачного для инфракрасных лучей укрытия. Полученные результаты обеспечивают условия для нормального протекания химической реакции гидратации, твердения и набора прочности, что позволяет успешно решать задачи бетонирования при возведении зданий и сооружений из монолитного бетона и железобетона.</p></trans-abstract><kwd-group xml:lang="en"><kwd>concrete</kwd><kwd>temperature</kwd><kwd>heating</kwd><kwd>infrared radiation</kwd><kwd>monolithic reinforced concrete structures</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>бетон</kwd><kwd>температура</kwd><kwd>обогрев</kwd><kwd>инфракрасное излучение</kwd><kwd>монолитные железобетонные конструкции</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Rizzuto J.P., Kamal M., Elsayad H., Bashandy A., Etman Z., … Shaaban I.G.
