The life cycle of a capital construction facility is an economically feasible program for the design, construction, operation and abandonment of a building or structure. This article reveals the role of the life cycle project in the redevelopment of industrial facilities, such as above-ground plants and factories within the city and mining facilities. The article provides a methodology for drawing up a life cycle program for redevelopment of industrial (above-ground and underground) objects, a mine field.

The structures of the external walls of buildings of non-ferrous metallurgy enterprises are destroying under the influence of an aggressive production environment. The results of scientific research on the development of material for partial or complex repair of the external walls of buildings of non-ferrous metallurgy enterprises are presented. The material developed by the author belongs to the group of polymer silicate compositions. It is lightweight polymer silicate shungizit concrete (LPSHС). This material is highly resistant to acidic wet gas production environment, typical for non-ferrous metallurgy enterprises. Building structures made of this material do not need to be additionally protected with chemically resistant materials. Shungizite gravel was selected as a lightweight porous aggregate. This lightweight porous aggregate is obtained by firing a chemically resistant shungite mineral. Several polymer silicate compositions have been selected. The properties of compositions affecting the durability, chemical resistance and energy efficiency of exterior walls have been studied. The article presents the results of comprehensive studies of the physico-mechanical properties of a material, its chemical resistance, and thermal performance. It is also shown that the reinforcement in LPSHC is well preserved. Studies have shown that the use of the developed material can provide high operational reliability of the external walls of buildings of non-ferrous metallurgy enterprises. According to regulated quality indicators and a combination of properties, LPSHС meets the requirements for exterior walls of non-ferrous metallurgy enterprises. The article also provides a list of production workshops for the application of LPSНС. The material can be used in other industries with similar aggressive environments.

In many industries, production processes are connected with acidic wet-gas environments. These environments adversely affect building structures. The author suggests a light polymer-silicate schungisite concrete as a corrosion-resistant material of external walls. The use of this material will increase the service life of the walls of enterprises in a number of industries, where building structures are exposed to corrosive environments. Acid-resistant schungite and schungisite components were used in the material. The article presents the results of studies of the sorption humidity of a light polymer-silicate schungisite concrete. Sorption humidity was studied as a property that actively influences the energy efficiency and durability of external walls. It was concluded that the most favorable conditions for the work of the material from the point of view of its sorption-wetting are created at a relative humidity of air not exceeding 80%. The internal environment with relative humidity of air close to 90% can cause a sharp moistening of the material with sorption moisture.
