Abstract
Based on a long-term studies and research: the changes of carbonization in time along the cross-section of concrete of various classes in strengths; its effect on the change of the protective properties of concrete in relation to steel reinforcement; the conditions of steel reinforcement and concrete of the protective layer,- the graphical dependences have been obtained, allowing to estimate and predict the depth of corrosion damage of steel reinforcement; the average rate of its corrosion, the time of the onset critical damage to steel reinforcement and the formation of cracks with development of critical width from the thickness of protective layer for concrete of various classes on the strength, which are operated in conditions of open atmosphere. The nature of the dependencies obtained makes it possible to obtain in an analytical form the regression dependencies of the change in corrosion rate of steel reinforcement in carbonized concrete on various technological and operational parameters. That will allow much more objective predictions of the durability of reinforced concrete water pipes (culverts) much more objectively, both at the design stage and during operation.
