The particle size of silt ranges from
WebbThere are 12 classes of soil texture. For example, if most particles are large and coarse the soil is called a sand. It looks and feels sandy. A silt soil is dominated by medium-sized particles and feels like flour. Small-sized soil particles primarily make up a clay soil which feels slippery or greasy when wet.

Sand grains have a diameter ranging between 0.05 to 2 mm. Silt grains have a diameter ranging between 0.002 to 0.05 mm. Whereas clay grains have a diameter lesser than 0.002 mm. Sand, silt, and clay combine together to form loam. Combination of loam and sand is called sandy loam.
WebbIf the soil has 5–12% by weight of fines passing a #200 sieve (5% < P #200 < 12%), both grain size distribution and plasticity have a significant effect on the engineering properties of the soil, and dual notation may be used for the group symbol. For example, GW-GM corresponds to "well-graded gravel with silt.".

The Krumbein phi (φ) scale, a modification of the Wentworth scale created by W. C. Krumbein in 1934, is a logarithmic scale computed by the equation where
Webb11 apr. 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.
