Abstract
Resource potential of the mountainous part of the Chechen Republic for the production of modern repair and restoration binders and compositions
Incoming article date: 28.06.2023Repair and restoration binders and compositions based on them are needed primarily 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 have been identified that are promising for the identification of deposits of carbonate, halogen and clay raw materials, mainly as lime, cement and multi-purpose. The work uses methods of analytical research and scientific generalizations, expert assessments, process modeling and system analysis. 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. As a result 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. To assess and correct the scientific problem associated with the development of repair and restoration binders and repair and restoration compositions, a review of historical experience was made. 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.
