Abstract
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.
