Abstract: | On the basis of the thermodynamics of irreversible processes, a solution has been obtained for the problem of mass transfer between nonfreezing interlayers in a slit model of a pore filled with ice, and also between the thawed and frozen zones of a porous solid. The disjoining pressure plays a role in determining the equilibrium thickneses of the interlayers and in the phenomena of frost damage and heaving of soils. The theory that is developed in this work is supported by experimental findings, and guidelines are formulated for future research in the field of the theory of moisture movement in porous solids during the freezing process. |
