Energy saving, operational reliability of buildings and structures for various purposes is determined by the durability of building materials and products used in their construction. To date, frame building composites have been developed on the basis of polystructural theory. The frame technology for the manufacture of building products consists in the preliminary manufacture of frames from coarse-pored mixtures, followed by filling voids in the hardened frame with a matrix-plasticized binder, fine-dispersed or fine-grained composition, while the frames and matrix can be formed on various binders. This technology makes it possible to obtain building materials and products with a combination of the most diverse and even incompatible binders with a predetermined set of properties, i.e. opens the way to directional materials science. The paper presents the results of theoretical research and calculation of the technological physical and mechanical properties of frame composite building materials. The regularities of the structure formation of frame composites at the level of the formation of frames and matrices, as well as when they are combined, are revealed. It is established that the process of impregnating the frame with a matrix obeys the laws of motion of freely dispersed or connected dispersed systems. Formulas for calculating structural stresses in hardening frame composites are derived. Analytical dependences for calculating the thermal conductivity coefficient of products are obtained from phenomenological positions. Expressions for the calculation of the modulus of elasticity are obtained for models of ordered aggregates and the kinetics of the processes of destruction of frame composites under their loading is shown. Theoretical dependences for calculating the diffusion coefficient in frame composites on the main structure-forming factors are established.

Энергосбережение, эксплуатационная надежность зданий и сооружений различного назначения определяется долговечностью применяемых при их возведении строительных материалов и изделий. К настоящему времени на основе полиструктурной теории разработаны каркасные строительные композиты. Каркасная технология изготовления строительных изделий заключается в предварительном изготовлении каркасов из крупнопористых смесей с последующим заполнением пустот в отвердевшем каркасе матрицей - пластифицированным связующим, тонкодисперсной или мелкозернистой композицией, при этом каркасы и матрица могут быть сформированы на различных связующих. Данная технология дает возможность получать строительные материалы и изделия с сочетанием самых различных и даже несовместимых вяжущих с заранее заданным комплексом свойств, то есть открывает путь к направленному материаловедению. Представлены результаты теоретических исследований и расчета технологических и физико-механических свойств каркасных композиционных строительных материалов. Выявлены закономерности структурообразования каркасных композитов на уровне формирования каркасов и матриц, а также при их объединении. Установлено, что процесс пропитки каркаса матрицей подчиняется закономерностям движения свободнодисперсных или связнодисперсных систем. Получены формулы для расчета структурных напряжений в твердеющих каркасных композитах. С феноменологических позиций получены аналитические зависимости для расчета коэффициента теплопроводности изделий. Для моделей из упорядоченно расположенных заполнителей получены выражения для расчета модуля упругости и показана кинетика процессов разрушения каркасных композитов при их нагружении. Установлены теоретические зависимости для вычисления коэффициента диффузии в каркасных композитах от основных структурообразующих факторов.
