Introduction. Methodological approaches and validation of the emergence of a new transdisciplinary area -geonics, which is considered as the art of applying knowledge of the inorganic world, are presented.Materials and methods. The concept of technogenic metasomatism as a stage in the evolution of building materials, characterized by the adaptation of the composite to changing conditions is formulated. The Law of affinity of structures, which consists in the selection of raw materials for a composite with similar physical and mechanical characteristics, is described.Results. The examples of non-traditional raw materials use in the areas of construction materials science (intelligent composites, restoration mixtures) and architecture (the building of the Belarusian Potash Company in Belarus, the 'Reflection of the mineral’ building in Japan, the design concept of the monument to the Kursk magnetic anomaly) are presented.Discussion and conclusions. It is proved that the development of a transdisciplinary approach to geonics will improve the comfort of human stay in the environment.
Construction 3D printing is one of the advanced construction technologies in the era of widespread digitalization. The main idea of construction printing is to create a finished product or structure with one installation according to a given digital model. One of the obstacles to widespread implementation is the lack of integrated solutions for the construction of printed walls, ensuring the fulfillment of both structural and thermal engineering requirements, as well as the lack of available materials that allow obtaining mixtures for construction printing, maximally optimized for the features of a 3D printer. At the same time, an important condition for the commercial attractiveness of 3D technologies is the minimization of initial costs, as well as the availability of raw materials that contribute to their development by small and medium-sized businesses. The article offers a comprehensive solution for the development and creation of wall structures, consisting in alternating printing with one device (in different modes) of a fixed formwork made of fine-grained concrete with filling the interior space with a foam concrete mixture based on gypsum cement binder. This solution ensures the fulfillment of structural and thermal engineering requirements based on available standard components (commodity binders), maximally optimized for the features of the construction printer.
The article considers the solution of the urgent problem of the development of 3D additive technologies in Russia by creating a new model of the forming device and the development of composite materials. The purpose of this work is to study the physical, technological and thermal properties of coarse-pored expanded clay concrete. The required characteristics are determined by standard methods and requirements of regulatory documents, including modern physico-chemical methods of analysis and a wide range of modern and original research methods corresponding to modern scientific knowledge. Results. Compositions of coarse-porous expanded clay concrete with compressive strength up to 9.2 MPa, water absorption up to 25% by weight and shrinkage deformations in the range of 0.1...0.3 mm/m were obtained. To simulate the behavior of the studied systems, a two-factor three-level experiment was conducted for each type of mixture of coarse-pored expanded clay concrete, which allowed us to obtain regression equations characterizing the relationship of variable parameters with certain properties of the system. It was revealed that the value of the average density is most affected by the specific consumption of the binder. While the strength depends most on the I/O ratio. Moreover, in this case, the amount of water is less related to the porosity of the cement stone itself, and more to the consistency and stickiness of the resulting glue, its ability to evenly cover the filler particles. It is established that rationally selected compositions of structural and thermal insulation KPKB for the internal filling of a three-layer "printed" wall, homologation and thermal insulation will ensure the formation of the required technical and operational indicators.
