ICE FORMATION IN CLAYS WITH SPECIAL REFERENCE TO THEIR MICROSTRUCTURAL CONSTITUTION

Microstructural changes caused by slow freezing were investigated by means of scanning microscopy. Two soft, illiatic clays with quite different microstructural constitutions but otherwise similar compositions and properties were tested. Preliminary tests show that the typical shear distortion associated with consolidation occurred in soil regions between ice accumulations. The fairly well-preserved character of many aggregates indicates that the intra-aggregate water did not freeze. Since the number and total volume of such aggregates are larger in the fresh-water clay this would correspond to a larger amount of unfrozen water in this clay than in the marine clay. /TRRL/
