Abstract
Sorption humidity of light polymer-silicate concrete for exterior walls of buildings with wet-gas media
Incoming article date: 16.03.2018In 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.
