Research into the causes of cement stone corrosion in the event of emergency destruction of reinforced concrete bridge structures

Artur Onyshchenko Valentyna Kovalenko Oleksii Rykovtsev Vitalii Kovalchuk

The article is dedicated to the investigation of the condition of the bridge structures on Povitruflotsky Avenue over the Lybid River in Kyiv. To this end, methods of selective assessment of reinforced concrete superstructure elements were applied, along with express techniques for microstructural, micro-X-ray spectral, and fractographic analyses. Objective – To investigate and identify the causes of the emergency failure of bridge structures over the Lybid River. Methodology – The causes of the emergency failure of the bridge superstructure were studied by examining the microstructure and chemical composition of samples of concrete damaged by corrosion as well as intact concrete from the bridge. Results – It was found that the concrete at the interface between sand aggregates and cement stone contains an elevated amount of alkali metals and halogens, exceeding national standard requirements several times. The average sulfur oxide concentration is 4.93% by mass. Localized increases in its concentration reach 6.15% by mass, significantly exceeding the regulatory limit of 3.5% by mass. In addition, a significant carbon content in the cement stone structure of all samples indicates its carbonation, which further reduces the mechanical properties of the concrete in the bridge structures. Conclusions – To prevent premature concrete failure in bridges, overpasses, and highways, it is recommended to monitor the quality of concrete in existing structures and during the construction of new facilities using express microstructural analysis methods. For visual monitoring of corrosion rates, it is suggested to install a gypsum marker on cracks in the bridge support columns on the sidewalk side. To mitigate the active influence of halogens on structural transformations in concrete in service, it is proposed to investigate the possibility of using less aggressive substances that will have a lower impact on corrosion processes in concrete and reinforcement of reinforced concrete structures while still effectively assisting in the removal of snow from sidewalks and roadways
