Dependence of foam concrete properties on technological factors


The dependences of foam concrete properties on various factors, which are divided into four groups, are considered. The dependence of physical and mechanical properties on the properties of materials, conditions for maintaining foam concrete, on the brand and mineralogical composition of cement was revealed. Joint and separate methods of preparing a foam concrete mixture are considered using pressure-chamber turbulence cavitation mixers and modernized standard forced-action mortar mixers. The importance of the technological influence of temperature in foam concrete technology is determined. Methods of transporting foam concrete mix, which also affect the material's properties, are considered. Foam concrete is a light cellular concrete obtained by hardening a cement, sand, water, and foam solution. The foam provides the necessary content and even air distribution in the concrete. The foam is obtained from a foam concentrate (foaming agent). Various organic and inorganic compounds can be used as a foaming agents: those obtained based on natural protein and synthetic ones obtained in the production of detergents. The physical and mechanical properties of foam concrete depend on several factors, which can be divided into four groups: factors due to the properties of materials and their quantitative ratios; technological factors; structural and technological parameters of equipment; conditions for maintaining foam concrete. Varying the number of components makes it possible to obtain heat-insulating, heat-insulating, and structural foam concrete: super light, light, medium density, and heavy with a density, respectively, of 100 - 300 kg/m3, 300 - 600 kg/m3, 600 - 1000 kg/m3, 1000 - 1600 kg/m3. At the same time, a mixture of foam concrete with a density of 100 - 600 kg/m3 is prepared without sand. The type of foaming agent significantly impacts the quality of foam concrete. So, to obtain high-density foam concrete, synthetic foaming agents are usually used, which affect the strength of the foam concrete, but increase the time of setting and strength gain.
