Grain Size Distribution
|
The grain size distribution “determines the mass percentages of the various grain size ranges found in a soil sample”. The particle size distribution is illustrated using the grading curve (grain size distribution curve) and determined by dry screening. The grading curve y(d) defines the mass percentage y of the particles with a diameter smaller than d in a given sample [ASTM D422] [DIN18123]. |
