Determination of particle size distribution
WebApr 11, 2024 · The statistical analysis results indicate that D50 and Cu ( Cu ′) are the most appropriate indexes to represent the PSD of standard sands. As mentioned above, D50 indicates the size for which the mass fraction of smaller particle size is equal to 50%, and is the integral result of particle size distribution density function. WebOct 4, 2014 · The particle size distribution derived from this method is the size distribution of spheres that, when applied to the mathematical model, most closely reproduce the experimental penetration data. Considering this, MIP could be a suitable technique to determine the PSD of fly ashes.
