Size ranges define limits of classes that are given names in the Wentworth scale (or Udden–Wentworth scale) used in the United States. 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 $${\displaystyle \varphi =-\log _{2}{\frac {D}{D_{0}}},}$$where

Unified Soil Classification System - Wikipedia

The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain s…

Particle size, also called grain size, means the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be used for other granular materials. In some schemes "gravel" is anything larger than sand (>2.0 mm), and includes "granule", "pebble", "cobble", and "boulder" in the above table.

Classification of Soil on Particle Size and Moisture Content

The Unified Soil Classification System is used for virtually all geotechnical engineering work except highway and road construction, where the AASHTO Classification of Soil is used. Both systems use the results of grain size analysis and determinations of Atterberg limits to determine soil’s classification. Soil components may be described as gravel, sand, silt, or clay.

Sand-sized particles range in size from 63 microns to 2 millimeters. Gravel is anything larger than that; silt and mud are finer. When we think about sand, we usually picture quartz sand, because that's what most sand is made of on Earth. But the term "sand" does not specify composition, it only specifies grain size.

To introduce the sizes most commonly used the Red Spheres denote 0.425 mm, Green 0.212mm, Yellow 0.3mm, Salmon 0.15mm and an undesirable black sphere at 0.075mm or 75 microns. Ideally the sand grains should be spread across four sieve sizes in a Bell type distribution.

media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging.
