Zusammenfassung:Factors, which cause fracture of reinforced concrete constructions of bridge structures were considered. One of them is anti-icing material used for road safety in the winter period. The Ukrainian market of anti-icing chemical reagents and combined agents of natural and industrial origin was analyzed. The kinetics of corrosion fracture of 09G2S and St3 steels as the main material of reinforcement in neutral chloride-containing and alkaline solutions was investigated using the method of polarization resistance. Taking into account the kinetics of corrosion fracture of the studied steels, the rate of their general corrosion was calculated.
