AbstractAbout AuthorsReferences
In the course of operation, reinforced concrete structures are subjected to the impact of various aggressive media, carbon dioxide is the most common among them. As a result of this physical-chemical impact, the concrete loses protective properties with regard to reinforcement. The situation is aggravated by the presence of cracks through which the access of carbon dioxide to the zone of reinforcement location is accelerated. Main provisions for calculating the depth of concrete neutralization under the impact of carbon dioxide, without cracks as well as in case of their formation, are considered. Accounting methods for the presence of cracks in reinforced concrete structures when determining the speed of concrete neutralization are proposed.
