HYDRO CHEMICAL CRUSHING AND CORROSION OF METAL CONCREATE CONSTRUCTIONS OF BIG PUMPING STATIONS

Abstract

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 conducted studies, it was found out the increased content of sulfuric acid salts and other chemical elements in groundwater, which promote the formation of calcium sulfoaluminate (cement bacillus) in the structure of reinforced concrete structures. The analysis of the conducted researches allows to draw a conclusion that the main factors that influence and intensify this process are: aggressive action of groundwater and filtration water, as well as constant influence of electric current. All these factors, contributing to the development of corrosion processes of reinforced concrete structures, lead to a significant decrease in strength properties, and in some cases, their partial destruction. In this connection, there is now an urgent need for a detailed study of the processes under consideration and the development of necessary measures to prevent and eliminate them.
