A modified method for estimating fine and coarse fractal dimensions of soil particle size distributions based on laser diffraction analysis

Purpose Particle size distribution (PSD) is one of the most commonly measured physical properties of soil. The fine fractal dimension, Df, and the coarse fractal dimension, Dc, are, respectively, based on the fine and coarse size fractions of soil particles. Laser diffraction effectively determines the volume PSD of soil. Original and modified methods for determining the Df and Dc of the volume PSD of soil are derived and presented in this work.
