Chemical factors in soil freezing and frost heave / J. Kenneth Torrance, Fons J. Schellekens.

Title: Chemical factors in soil freezing and frost heave / J. Kenneth Torrance, Fons J. Schellekens.
Author(s): Torrance, J. Kenneth.
Schellekens, Fons J.
Date: 2006.
In: Polar Record. (2006.), Vol. 42(220) (2006)
Abstract: Examines chemical factors essential in frost heaving of soils through consideration of process of ice formation and role of temperature gradients in generating water potential gradients in freezing soils. Identifies osmotic re-supply of unfrozen films between ice-lens base and underlying soil as source of force that lifts overlying material to generate frost heave, with osmotic pressure being controlled by local temperature.
