A promising direction for further development of composite materials is the employment of pre-bound aggregate materials. Their production is a two-stage process, which involves at first creating an optimal aggregate mix and gluing the grains to each other and secondly filling the voids of the obtained aggregate framework with a high-workability matrix. Presented research is an experimental investigation of physical and technical properties of pre-bound aggregate composite materials. Composites with complex binders are also considered in this study. In such cases, the aggregate framework and the grouting matrix were made of binders of different nature, which are incompatible when the components are mixed ordinarily. When studying composites, a complex of physical and mechanical methods was used. Improvement of physical and mechanical properties of framework composites in comparison with composites obtained according to conventional techno- logy has been established. These advantages are identified primarily for such properties as deformability, impact strength, creep.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Применение при строительстве и реконструкции зданий и сооружений различного назначения новых строительных материалов и изделий, обеспечивающих улучшение их эксплуатационных показателей, повышение эффективности, снижение материалоемкости, стоимости и трудоемкости изготовления, является актуальной задачей. Перспективным направлением дальнейшего развития строительных композитов представляется получение и внедрение материалов каркасной структуры. Технология их изготовления включает предварительное создание оптимальных смесей заполнителей и склеивание зерен друг с другом с последующим заполнением пустот полученного каркаса высокоподвижной матрицей. Исследование посвящено экспериментальному изучению физико-технических свойств каркасных композиционных материалов. В качестве исследуемых объектов рассматривались композиты, составленные на различных связующих, в том числе на комплексных. В последнем случае каркас и пропиточная матрица изготавливались на связующих различной природы, порой несовместимых при обычном смешивании компонентов. При исследовании композитов использовался комплекс физико-механических методов. Установлено улучшение физико-механических свойств каркасных композитов при сравнении их с композитами, полученными по общепринятой технологии. Данные преимущества выявлены в первую очередь для таких свойств, как деформации, ударная прочность, ползучесть.</p></trans-abstract><kwd-group xml:lang="en"><kwd>composites</kwd><kwd>framework structures</kwd><kwd>framework</kwd><kwd>matrix</kwd><kwd>flexural strength</kwd><kwd>fracture toughness</kwd><kwd>deformability</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сompressive strength</kwd><kwd>композиционные материалы</kwd><kwd>каркасные структуры</kwd><kwd>каркас</kwd><kwd>матрица</kwd><kwd>материалы</kwd><kwd>армированные волокнами</kwd><kwd>прочность на сжатие</kwd><kwd>прочность на изгиб</kwd><kwd>ударная вязкость</kwd><kwd>деформативность</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Solomatov V.I., Bobryshev A.N., Himmler K.G.
