Combustibility of lightweight foam concrete based on natural protein foaming agent

There is an experimental study of monolithic foam concrete "SOVBI" samples 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, and 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. Monolithic foam concrete is used for enclosure structures in the form of lightweight steel concrete structures, retaining walls, and backfill materials for highways, railways, and plazas. This material is characterized by a low density, good sound insulating properties, and high thermal insulation capacity, while it exhibits sufficient compressive strength for the load-bearing function. The use of monolithic foam concrete makes it possible to simplify and reduce the cost of construction and increase the volume of work more than ten times, compared with laying aerated concrete and foam concrete blocks, with a significant reduction in the number of workers. It also minimizes the use of cranes and lifting and reduces transport expenses and the area of the zones of materials storage.
