説明
It has been suggested that plasticity of clay has been connected with the water in the vicinity of the surface of clay particles. Previously, we have revealed that the plasticty of clay was strongly related to the thickness of the water (bound water) on the surface of clay particle obtained from the measurement by the Pfefferkorn method. In the present work, we have investigated the relation between the plasticity and the thickness of the unfrozen water obtained from measurement of DSC (Differential Scanning Calorimetry) for many kind of natural clays, and compared both the thickness of bound water and the unfrozen water. Following results were obtained: 1) a linear relationship was observed for the thickness of unfrozen water and bound water. 2) the thickness of bound water was about 1/3 of that of unfrozen water. 3) the thickness of unfrozen water was applicable to the index for the plasticity of clay as well as that of bound water. 4) DSC peak suggested micro pores (for example which were in halloysite).
