摘要：
Using the thermodynamics of irreversible processes as the basis, the problem of the mass exchange between nonfreezing interlayers has been solved for the slit model of a pore filled with ice, as well as between the thawed and the frozen zone of a porous body. There was shown the important role of disjoining pressure in the formation of equilibrium thicknesses of interlayers and the phenomenon of the frost destruction of porous materials and frost heaving. Experimental corroboration of the developed theory is presented. The problems have been formulated involving further investigations in the field of the theory of motion of moisture in frozen porous bodies.
