Effect of concreting defects on the uptime of reinforced concrete during the construction of new Arctic settlements by the criterion of exposure to air carbon dioxide
Abstract The development of Arctic territories and waters requires the construction of new settlements with industrial infrastructure. Modified concrete is used for the construction of these facilities. However, during erection of monolithic reinforced concrete structures defects and damages are for...
