AbstractAbout AuthorsReferences
External enclosing structures of premises of residential and public buildings are often constructed with the use of building materials containing hygroscopic salts and their mixes which are introduced as technological additives regulating properties and processes of material hardening, come from the environment, either present in the initial raw material. The presence of salts contributes to improving sorption properties and moisture content of wall materials that worsens the sanitary condition of the premises. The necessity to take into account the influence of salts when establishing the humidity conditions in premises of such buildings is shown; the procedure of engineering calculation of the partial pressure of saturated water vapour at presence of some salts in the wall material of premises as well as their mixes at different temperature corresponding to the operation conditions of external enclosing struc- tures is proposed.
