Identification of a materials destruction nature with simultaneous exposure to freeze / thaw cycles and chloride environment

Abstract

The article is the first to consider the simultaneous impact on concrete structures of two destructive factors: low temperatures and aggressive environments, which are chloride-deicing agents (CDA). Then the results of experimental data obtained are presented. Finally, it is concluded that that with the simultaneous action of two factors on concrete, instantaneous destruction of concrete occurs due to the action of the Rebinder’s effect, and not to the process of chemical corrosion, as it was thought earlier.
