| Comment |
The effects of open-system freezing can be quite different for different soil materials. During freezing of clean, medium- to coarse-grained materials, some pore water may be expelled ahead of the freezing front (compensating for the volume increase during phase change) thus reducing frost heave. During freezing of fine-grained materials, however, water often migrates to the freezing front, contributing to the formation of segregated ice, thus causing increased frost heave.
