Hydrochemical destruction and corrosion of reinforced concrete structures of large pumping stations

The work aims to study the hydrochemical destruction and corrosion of reinforced concrete structures of large pumping stations in the Republic of Uzbekistan.This article is devoted to one of the main problems of the process of hydrochemical destruction of massive reinforced concrete structures -corrosion of reinforcement in the foundation parts of buildings of large pumping stations.Based on the analysis of the studies carried out, an increased content of sulfate salts and other chemical elements in groundwater was found, which contributed to the formation of calcium sulfoaluminate (cement bacillus) in the structure of reinforced concrete structures.An analysis of the studies carried out allows us to conclude that the main factors influencing and enhancing this process are the aggressive action of ground and seepage waters, as well as the constant effect of electric current.All these factors, which contribute to the development of corrosion processes in reinforced concrete structures, lead to a significant decrease in strength properties and, in some cases, their partial destruction.In this regard, there is currently an urgent need for a detailed study of the processes under consideration and the development of necessary measures to prevent and eliminate them.
