“…The researches [23,24] provide information about fire resistance lightweight steel concrete structures, composed of profiled steel filled with a monolithic foam concrete with a 200 kg/m 3 -400 kg/m 3 density, and with fiber cement sheets sheathing. The actual fire resistance limit of samples of the wall panel fragment is REI 60 with a uniformly distributed load of 20 kN/m [23]. Actual fire resistance limit of samples of the slab panel fragment at least REI 60 with a uniformly distributed load of 4 kN/m 2 [24].…”

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.

There is an experimental study of samples of monolithic foam concrete “SOVBI” with a density of 205 kg /m3 (grade D200) for combustibility. The evaluation criteria are the following values of combustion characteristics: temperature increment in the furnace, duration of the stable flame burning, sample mass loss. The experimental results show the following values for foam concrete: temperature increment in the furnace of 2 °C, duration of the stable flame burning of 0 s, and sample mass of 24.4%. Thus, monolithic foam concrete with a density of 205 kg/m3 is noncombustible material. It is proposed to use monolithic foam concrete and other lightweight monolithic cellular foam concrete, as a structural fire protection for lightweight steel concrete structures. It, in turn, can increase the fire resistance of external walls and floor structure with the steel frame of cold-formed zinc-coated profiles.
