【 摘 要 】

In the article the popular finishing material for civil construction, gypsum-fibrous boards, is considered. The importance of using fireproof materials in construction is discussed. The mechanism of resistance of known types of gypsum-fibrous boards to fire burning is considered. A method is proposed for improving the quality characteristics of gypsum-fibrous boards by replacing the currently used paper fiber with mineral or polymeric ones. It was suggested that it is possible to increase the fire resistance of gypsum-fibrous boards by the introduction of incombustible asbestos fibers. The properties of gypsum-fibrous boards with a full or partial replacement of paper fibers on glass fiber, basalt fiber, asbestos fiber and polymeric fibers have been studied. Densities, surface water saturation, coefficient of thermal conductivity and strength characteristics of boards were investigated, based on the developed compositions. The expediency of using asbestos fiber as a fiber for the production of gypsum-fibrous boards is established.
