Abstract
It is important to analyze quantitatively the micro-structure of clay and to correlate the results with the mechanical behavior of clay. Studies are conducted on consolidated Illite and DL-soil samples, and the Color Laser 3D Profile Microscope is used. Sm-value, Fractal dimension and Fourier transformation are employed for the analysis. The results from these quantifications show some influence of measurement conditions. Thus, the measurement conditions must be carefully selected. The results of the analysis indicate the difference of the particle size of the samples and the change of the micro-structure of the samples before and after the consolidation, especially by Fractal and Fourier methods.
