Influence of the Baltic Sea water on Klaipeda seaport hydrotechnical structures

Hydrotechnical constructions in Klaipeda Seaport are constantly affected by the Baltic Sea environment (humidity, temperature changes, freezing and thawing effects, etc.). Hydrotechnical concrete is negatively affected by the Baltic Sea water, consisting of certain amounts of salts, highly repetitive moistening and drying (sorption and desorption) processes. Hydrotechnical concrete is characterized by capillary porosity, which is typical of Klaipeda Seaport hydrotechnical structures - quays, because they constantly rise in sea water at different levels of the surface. The aim of the study was to determine the influence of mineral additives on the type of gum, regulating sorbent parameters. The experimental results obtained will provide an opportunity to predict the durability of hydraulic concrete according to its sorption characteristics and damage to corrosion.
