There have been carried out calculations that show the efficiency of using high-strength and highly mobile repair compound «Gidrobeton Nalivnoj-2» (manufactured by LLC «Kalmatron-SPb») to strengthen reinforced concrete bending elements exposed to freezing and thawing cycles. The results of experimental studies were used as initial data. As a result of calculations, it has been found out that the greatest effect is achieved for beams with a small, close to minimal, and high (exceeding µ<sub> R </sub>) percentage of reinforcement.
