RELATIONSHIP BETWEEN THE ICE AND UNFROZEN WATER PHASES IN FROZEN SOILS AS DETERMINED BY PULSED NUCLEAR RESONANCE AND PHYSICAL DESORPTION DATA

An experiment is described that demonstrates the balance between the ice and the unfrozen water in a frozen soil as water is removed.Nuclear magnetic resonance (NMR) is used to monitor the unfrozen water content as the soil is dehydrated by a molecular sieve material.Our results show that the unfrozen water content of a Morin clay soil remains constant until the total water content has been reduced to the point where no ice remains in the system Once the ice is depleted,the unfrozen water content determined by NMR corresponds to the total water content of the soil determined by the weight of water removed by the molecular sieve material. Thus the validity of utilizing NMR in determining unfrozen water contents vs.temperature is established.
