Abstract
Difference in the micro-structure of clay can be shown qualitatively by the electron microscope, but there are few researches that have evaluated it quantitatively. Studies are conducted on Tokyo Alluvial Clay, and the Color Laser 3D Profile Microscope was used. Fractal dimension and Fourier transformation were employed for the analysis. After the measurement and analysis on the undisturbed and reconstituted samples, the present study indicate quantitatively the difference in the micro-structure of clays. Changes in the micro-structure of clay by the consolidation are also detected. Moreover, difference of the results by the sample preparation process between air-drying and freeze-drying is discussed quantitatively.
