“…Долговечность всегда являлась объектом пристального внимания как разработчиков, так и эксплуатационников, оказывая существенное влияние на стоимость объекта и затраты в эксплуатационный период. Высокие требования в строительстве способствуют поиску новых эффективных технических решений, которые бы позволили увеличить качество и долговечность объектов строительства, а также снизить энергетические и финансовые затраты по их содержанию и эксплуатации [1][2][3][4][5][6][7][8][9][10][11][12]. Очевидно, что срок службы строительных конструкций зависит как от условий их эксплуатации, так и от свойств материала, из которого они произведены, в том числе способности сопротивляться внешним воздействующим факторам [13][14][15][16][17][18][19][20][21].…”

The results of the analysis of scientific and technical literature, reflecting the experience of research of Russian scientists in the field of self-healing of building materials are shown. They are presented in publications included in international bibliographic and abstract databases. The tendency of changes in the number of publications over 10 years indicates an exponential growth in the interest of researchers in the ability of self-healing, most of the works (more than 50%) published in the field of materials science. The total number of publications by Russian authors over ten years devoted to self-healing is 206 works, of which 49% are in the field of materials science. An analysis of articles in publications included in international bibliographic and abstract databases published by domestic authors shows that methods of creating a material structure, which contains additional elements in the form of a reserve volume of a structure-forming substance, are proposed to implement the self-healing effect. Such elements are capsules or functional layers with a reducing agent, the destruction of which triggers the recovery (healing) process. Works are presented where the recovery effect is achieved due to the binder's own potential, which is not fully realized at the initial stage of structure formation. The authors have proposed the implementation of the self-healing effect in composites based on a hydraulic mineral binder (cement) and an organic binder (bitumen) or polymer. At the same time, in most cases, there is no mathematical description of self-healing mechanisms.

Improving the environmental situation and obtaining hydration hardening composites with new properties for various operating conditions is possible with the use of secondary resources. The work is dedicated to the criteria study for assessing the hydration hardening binders impact on the environment. The methodological approach to the choice of a functional unit for a carbon footprint comparative assessment of cement is substantiated in the work. The study results of the properties that determine the concrete durability in transport construction and the aggressive environment of livestock farms are presented. Concrete based on Portland cement has the least resistance in the aggressive environment of livestock complexes, the cross-breaking strength of which is almost twice after 150 days of curing. Marginally better resistance coefficient indicators in an aggressive environment have binder compositions based on portland blast furnace slag cement and technogenic raw materials. At the same time, if the process of degradation and decrease in the strength properties of the binder samples on Portland cement is progressive until they are completely destroyed, then in the binder samples on modified technogenic raw materials, the strength characteristics stabilize with time, which indicates the decaying nature of the corrosion process. The investigated slag-alkaline concrete satisfies the requirements for paving concrete and concretes for under-rail structures, since compressive strength and frost resistance were 70 MPa and F600 for granulated blast-furnace slag with a basicity modulus of 0.8; 78 MPa and F700 for granulated blast-furnace slag with alkali-lime index 0.9. These concretes had comparable characteristics to concrete on Portland cement CEM 52.5, for which the values were 60 MPa and F600. The presented results contribute to the development of an ecological approach to making design decisions in construction.

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.
