The paper presents the results of diagnostic measurements realized in the reinforced concrete tanks of sewage treatment plant in Žilina. Diagnostic measurements preceded the subsequently realized reconstruction. The purpose of diagnostic was to determine the carbonation of concrete, concrete covers, diameters and type of reinforcements and corrosion of reinforcement. In some samples of concrete, there were made the chemical analysis and determined the concentration of chloride ions Cl– and concrete composition.
Keywords: diagnostic of tanks, chemical analysis, rehabilitation, reinforced concrete, sewage treatment plant.
