Method for Assessing the Durability of Concrete of Offshore Structures at the Construction Stage

The problems that arise when implementing design indicators for the durability of concrete at the stage of construction of offshore structures under frost conditions are considered. It is shown that the standardized indicator of durability – frost resistance, due to the lack of operational methods of determination, is not controlled at the stage of manufacturing structures, which entails the production of both “eternal” concrete, the service life of which is 100 years, and concrete with a short service life. On the basis of modern theoretical principles of the structural theory of cement concrete and experience in the construction of offshore structures, a method for ensuring standardized frost resistance at the construction stage is proposed, provided that the critical maturity of the concrete structure is ensured by the beginning of frost exposure. A methodological basis for determining the critical maturity of concrete structure is given.
