Freezing phenomenon of water including small particle has two special characteristics : (1) the particles are swept from freezing front; (2) the particles are trapped by the progress of freezing. In this paper, we investigate the difference in behavior of glass particle and bentonite particle due to freezing. Two kinds of experiment had been investigated; there are single particle interactions with solidification surface and bulk particles interaction with solidification surface. From these results, it became clear that the critical freezing velocity of bentonite is larger than glass particle. And it became clear that the critical freezing velocity of bentonite strongly depends on the bulk particle concentration.
