Outline of Final Research Achievements

In this study, we examined the effects of pore structure on the thermal diffusivity of water-saturated rock under freezing process and obtained the following findings. The effect of pore water on the thermal diffusivity of water-saturated rocks is different in “water in clay minerals” and “water between mineral particles.” In other words, the freezing of water between mineral particles increases the diffusivity, whereas the water in clay minerals (i.e., adsorbed water, interlayer water, and constitution water) does not affect the diffusivity at all. Furthermore, we examined the presence/absence of freezing of water in clay minerals under low temperature. As a result, it could not get a clear conclusion.
