摘要：

It is known to use heat-insulating materials with a rigid cellular structure on cement, gypsum, liquid glass binders as a constructive fire protection. The described technologies for the manufacture of such materials do not allow combining a binder with an aggregate. The use of frame technology made it possible to obtain a material with an aggregate on a porous burned soda-lime-silicate waterproof binder. The article presents the results of studies of the fire-proof properties of samples from the obtained material. The deformation and heat-insulating characteristics of the material when heated are used as criteria for fire-proof properties. Volumetric heating of the material to a maximum temperature of 892 °C was carried out when studying the deformation characteristics. The heat-insulating characteristics of the material were studied during one-sided heating of a material sample in the form of a tile to a maximum temperature of 1050 °C. The characteristics obtained indicate that the material can be used for fire-proof lining of building structures and as for the construction of screen walls and as a filling material in fire barriers. © V.T.
