Жаростойкие пенобетоны приобретают начальную прочность за счет процессов гидратационного твердения глиноземистого цемента, обеспечивают фиксирование пористой структуры пенобетонов и набирают конечную прочность 0,3–3,2 МПа после отжига при 1000 °С за счет процессов твердофазного спекания глины с другими компонентами сухой смеси при их нагревании до 1000 °С, которые в отличие от пенобетонов на основе портландцемента и глиноземистого цемента не снижают, а наоборот, увеличивают свою прочность. Введение в состав сухой смеси ускоряющей и пластифицирующей добавки «Цитрат-Т» приводит к повышению реологических свойств вспененной пеномассы и сокращению времени ее схватывания и твердения. Установлена существенная роль водотвердого отношения при получении пенобетонов: с повышением водотвердого отношения с 0,45 до 0,70 увеличиваются объем пеномассы после вспучивания, неоднородность пор и их размеры, что приводит к уменьшению плотности пенобетонов и прочности на сжатие.</p></abstract><trans-abstract xml:lang="en"><p>The composition of dry mix on the basis of two-component cementing agent (aluminous cement and clay of the “Kustikha” field), mineral additives (a metakaolin, the RSAM sulfoaluminate modifier, waste of basalt fiber), Ufapore foamer and the accelerating and plasticizing “Citrate-T” additive is developed. When mixing “Citrate-T” additive with water at Water/Solid = 0.45–0.70, the subsequent mechanical binder and hardening of a foam mass heat-resistant foam concretes with a density of 300–650 kg/m3 are formed (depending on Water/Solid value). Foam concretes have strength on compression of 0.2–2.5 MPa before warming up when their initial strength depends on processes of hydration curing of aluminous cement that provides fixation of their porous structure. After annealing at 1000 °C foam concretes have final strength of 0.3–3.2 MPa due to processes of solid-phase agglomeration of clay with other components of dry mix at their heating. Foam concretes after annealing unlike foam concretes on the basis of a Portland cement and aluminous cement have big strength. Introduction of the accelerating and plasticizing “Citrate-T” additive into composition of the dry mix leads to an increase of rheological properties in expanded foam mass and time reduction of its drying and curing. It has been established that an essential role is played by the relation Water/Solid: at increase in the relation Water/Solid (with 0.45 to 0.70) occurs increase in volume of foam mass after a mechanical binder, and also heterogeneity of pores and their sizes increases that leads to reduction of density of foam concretes and strength on compression.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сухая смесь</kwd><kwd>жаростойкий пенобетон</kwd><kwd>минеральные добавки</kwd><kwd>пенообразователь</kwd><kwd>ускоряющая и пластифицирующая добавка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dry mix</kwd><kwd>heat-resistant foam concrete</kwd><kwd>mineral additives</kwd><kwd>foamer</kwd><kwd>accelerating and plasticizing additive</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">Gorlov Yu.
