Короткий огляд (реферат): The durability of concrete, the material which is widely used for water facilities depends on accumulation in operational environments (drain water, air-gas space) of hydrogen sulfide. Now the mechanism of corrosion destruction of concrete in drainage pipelines is represented as result of biogenous sulphuric acid aggression – influence of the sulphuric acid formed by thionic bacteria. The analysis of data on H 2 S concentration in drain waters of various industrial enterprises demonstrates that they create in gaseous operational media H 2 S concentration, sufficient for development in aerobic conditions of thionic bacteria. As the results of urban sewer networks inspection have shown, the correlation between concentration of H 2 S in aqueous phase and its concentration in air environment, between concentration of H 2 S in air environment and the corrosion rate of concrete’s coffering part is observed. Chemical and X-ray crystallography of this concrete showed that in corrosive concrete decreases pH, reaching in some examples of values 1-2, and sulfates collect. In dynamics of corrosion process the exponential growth of concentration in concrete of extremely acidophilic thionic bacteria is noted.
