Aggressive Groundwater Distribution in the City of Barnaul

Abstract

The paper focuses on the influence of aggressive groundwaters on concrete and reinforced concrete structures in Barnaul (Russia), affecting their durability. The exposure to aggressive waters can significantly reduce the reliability and safety of the operated buildings. The paper analyzes the chemical composition of groundwaters obtained from engineering and geological surveys in Barnaul. The processing of the products determined the type and intensity of the aggressiveness. The presence of aggressive groundwater was considered for each dedicated aquifer involved in the interaction between the geological environment and construction. The research resulted in the compilation of a map of aggressive groundwater distribution in Barnaul. The authors note that this problem is insufficiently studied, especially considering the technogenic load on the geological and hydrogeological environment and the accumulated experience. It is necessary to continue studies to determine the exact boundaries of the aggressive groundwaters in urban areas. Particular attention should be paid to geological processes of “flooding,” because they affect groundwater aggressiveness.
