Quantifying the morphology of crushed sand particles …
The moving average trend lines were used to characterize the evolutions of the particle size. The results indicate that a significant number of particles were crushed during the compression tests, resulting in a leftward shift of the major peak of the curve to a particle size of 0.3 mm (observed in CT-3, 4, and 5).

Particle Size Distribution Curve
And similarly D10 is the particle size for which 10 percent amount of soil has particles which are finer than this size. This particle size D10 is called Effective Size. If the value of uniformity coefficient is equal to the 1, that means D60 and D10 are the same particles. In that case the whole soil mass consists of only one grain size and ...

Calculating and Plotting Size Distributions
The size modulus is a measure of how coarse the size distribution is, and the distribution modulus is a measure of how broad the size distribution is. Size modulus for a size distribution can be determined from a graph by extrapolating the straight-line portion up to passing and finding the corresponding size value. The distribution ...
