Foam Gypsum in Modern Low-Rise Construction

The use of foam gypsum thermal insulation in the enclosing structures of low-rise buildings includes a number of advantages: the availability of gypsum raw materials, accelerated construction time, environmental friendliness during operation and fire resistance. The paper presents the technology of obtaining a foam gypsum mass. The raw material mixture containing gypsum binder, fillers and structuring additives is subjected to mechanical activation and vacuuming in a continuously operating cavitation activator-disintegrator without forced air supply with a rotor rotation speed of at least 3000 rpm. The result is a foam gypsum mass with an optimal size of bubbles forming pores, evenly distributed throughout the volume. The results of experimental determinations of the physical, mechanical and thermophysical characteristics of foam gypsum are presented. The results of the study of operational characteristics allow us to recommend the technology of pouring and slab foam gypsum in low-rise construction of houses from frame-cladding structures.
