Popis: The effect of a fireproof vermiculite-concrete layer on the bearing capacity of the reinforced cement layer was tested by testing single-layer and two-layer armocement elements under pure bending under the conditions of a "standard fire". Temperature fields were obtained for single-layer and double-layer structures with one-sided heating by the Vanichev's method of thermal balances. It has been revealed that a fireproof layer made of vermiculite concrete with a thickness of 15 mm makes it possible to increase the load-bearing capacity of a thin-walled reinforcement cement structure in comparison with a single layer of the same thickness by 25% under the conditions of the "standard fire" temperature for one hour.
