Аннотация: It was revealed that the influence of soluble salts on the hydrophysical properties of clayed minerals depends on the nature of minerals, the properties and state of salt (in solution or sorbing), and the region of fundamental hydrophysical characteristics (FHCH). The treatment of clayed minerals by NaCl, MgCl2, Ca(CH3COO)2, and ZnCl2 solutions increased their water-retention in the range NaCl > MgCl2 > Ca(CH3COO)2 ≈ ZnCl2. Pb(CH3COO)2 decreased the water-retaining ability of clayed minerals in all the FHCH range. A differential characteristic of the action MgCl2, Ca(CH3COO)2, and ZnCl2 on smectite is decrease of capillary water deduction.
