摘要

研究考虑了导致桥梁钢筋混凝土结构断裂的因素。其中之一是冬季用于道路安全的防冰材料。对乌克兰防冰化学试剂和天然及工业复合剂市场进行了分析。采用极化电阻法研究了作为主要加固材料的 09G2S 和 St3 钢在含氯中性溶液和碱性溶液中的腐蚀断裂动力学。考虑到所研究钢材的腐蚀断裂动力学，计算了其一般腐蚀速率。

Degradation of Reinforced Concrete Construction of Bridge Structures: Corrosion Aspect

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.
