AbstractThe parallel alignment of particles causes clay sediments to be anisotropic to thermal conduction. In marine sediments with a flocculated structure the anisotropy is small, while in fresh water clays that have a regular alignment of clay particles it is shown to be large. The anisotropy was shown to be related to particle alignment by comparing it with shrinkage results and particle orientation observed in thin sections. The sensitive relationships between anisotropic thermal conduction and particle arrangement are useful for investigating soil structure and because of this the transient heat flow method used is described in some detail.
