The study evaluates corrosion resistance of steel profiles in contact with monolithic foam concrete with a thickness of 5 and 10 mm. There are two types of samples: structural steel ones and cold-formed galvanized steel ones. A visual examination of samples exposed to high temperature and relative humidity is carried out. The corrosion resistance of profiles made of structural steel and cold-formed galvanized steel in full contact with monolithic foam concrete provides. Metal passivation (formation of a protective film) occurs due to the high alkalinity of foam concrete. The pH values of concrete and concrete mixture, experimentally obtained, vary in the range of 12.18 ... 12.36 at all stages of the structural behavior. This indicates a favorable highly alkaline environment for profile steel.
