Composite Reinforcement as a Way to Increase the Durability of Building Structures

The study of liquid corrosion of cement concrete was carried out, the results of which allow to determine the mass transfer parameters in the studied system and calculate the service life of the concrete product in environments of varying degrees of aggressiveness. Dates of the beginning of electrochemical corrosion of steel reinforcement in reinforced concrete and the achievement of the limit state of steel reinforcement in the conditions of liquid corrosion of reinforced concrete in a chloride-containing medium were mathematically calculated and experimentally established. Investigations of the corrosion resistance of fiberglass reinforcement in various environments have been carried out. The possibility of replacing steel reinforcement with fiberglass when reinforcing concrete products is considered.
