The analysis of concrete fracture in the process of exhaustion of its frost resistance. Statistical regularities and kinetics of ultimate strength upper limit of microdestruction and deformative values are established. A steady decline in the fracture toughness was found during cyclical freezing and thawing (FTC). Fatigue transformation of concrete long-term operation in severe climatic conditions is characterized with an increase in the danger of brittle fracture.
