Degradation effects of chloride ions on structures

Popis výsledku v původním jazyce

Structures located near roads are subject to increased environmental degradation because of the presence of airborne chlorides, primarily originating from de-icing salts such as sodium chloride (NaCl). This study investigates the deposition of chloride ions on a noise barrier located along the I/11 road in the Czech Republic using the wet candle method, as defined by ISO 9225. Measurements were carried out over multiple seasons on the obverse (road facing) and reverse (road opposite) surfaces of the barrier at various heights and distances from the road. The results clearly demonstrate seasonal variability, with significantly higher chloride ion deposition in the winter months and substantial differences between the obverse and reverse surfaces. The calculated deposition ratios indicate that the presence of the noise barrier substantially reduces the exposure of chloride ions on protected surfaces, especially near the road. These findings highlight the importance of structural orientation, surface positioning, and barrier design to mitigate chloride-induced corrosion. The results support more effective planning, maintenance strategies, and life-cycle assessments of infrastructure in chloride-rich environments.
