Restoration of urban monuments: the resource potential of the Northern Caucasus

Introduction. Repair and restoration binders and compositions based on them are necessary, first of all, for the repair, restoration and restoration of cultural heritage sites, both in the Russian Federation and abroad. They are subject to special requirements, so the conduct of related engineering and survey, research and development work is an important condition for the development of modern scientifically verified, practically tested and in demand in practice repair and restoration materials. One of the main conditions for the practical implementation of the proposed investment project is the presence of a mineral resource base in the region and the country. The resource potential of carbonate, halogen and clayey rocks is fully represented in the mountainous part of the Chechen Republic (CR). Based on the results of research and prospecting work on the territory of the Czech Republic, 6 forecast areas were identified, promising for the identification of deposits of carbonate Purpose of research. Development of compositions of binders for repair and restoration work based on the resource potential of the rocks of the mountainous part of the Czech Republic. Materials and methods. The work uses methods of analytical research and scientific generalizations, expert assessments, process modeling and system analysis. Results and discussion. The classification of inorganic binders was performed, which for the first time included organic-inorganic binders and additives in repair and restoration binders and compositions. Because of exploratory research, it was proposed to repair, restore and restore historical and cultural monuments using the ones developed at the Kh.I. Ibragimov RAS of modern technologies and materials for repair and restoration work. A concept for the development of a new scientific direction "High-strength composite materials based on lime (hydraulic and hydrate), gypsum (gypsum and anhydrite) and magnesia binders for the repair and restoration of cultural heritage sites" has been developed. Conclusions. The article presents the results of studies of repair and restoration binders and compositions based on them. It is shown that they are subject to special requirements, therefore, carrying out related engineering and survey, research and development work is an important condition for the development of modern scientifically verified, practically tested and in demand in practice repair and restoration materials. The paper shows that the new developed classification is more complete and allows more accurate determination of the compositions necessary for restoration work. According to the results of the work, it is clear that it is possible to carry out the repair, restoration and restoration of historical and cultural monuments using the proposed technology. When carrying out such work on the territory of the Chechen Republic, it is possible to do these using local raw materials. Resume. It is planned to continue work in this direction and analyze the sources of raw materials for restoration work in more regions of the North Caucasus.
