Soil Mechanics: LESSON 4. Classification of Soil
Soil with particle size in between 300 mm to 80 mm is called Cobble. The soil is called Gravel if particle size is in between 80 mm to 4.75 mm. The gravel is sub-divided as Coarse Gravel (80 mm to 20 mm) and Fine Gravel (20 mm to 4.75mm). Soil with particle size in between 4.75 mm to 0.075 mm is called Sand.

If more than half of the coarse fraction is gravel (retained on the No. 4 sieve), the soil is gravel and the first letter symbol is G. If more than half of the coarse fraction is sand, the soil is sand and the first letter symbol is S. For sands and gravels the second letter of the classification is based on gradation for clean sands and gravels and plasticity of the fines for sands and

Particle Size Fractions
Particle size fractions. The physical and chemical properties of soil are strongly influenced by the particle size distribution of soil particles. Although the particle size distribution is a continuum, it is conveniently broken down into size classes. Particle sizes range from less than 0.002 mm (e.g. clay) to greater than 2 mm (e.g. fine

Sediment Grain Size Chart for Rocks
Gravel forms coarse rocks with grains over 2 mm in size. If the fragments are rounded, they form conglomerate, and if they are angular, they form breccia. Sand, as you may guess, forms sandstone. Sandstone is medium-grained, meaning its fragments are between 1/16 mm and 2 mm. Silt forms fine-grained siltstone, with fragments between 1/16 mm and

What is the difference between Sand and Gravel?
Size classifications vary, but generally well-sorted sand has individual grain sizes of between 0.0625 mm and 4 mm, whereas gravel has individual grain sizes of between 4 mm and 75mm. The qualifiers ‘coarse’, ‘medium’, and ‘fine’ often precede ‘sand’ and ‘gravel’ to subdivide these size ranges further.

Grain Size : What is Grain Size? How is Grain Size measured?
In typical rivers the largest carried sediment is of sand and gravel size, but larger floods can carry cobbles and even boulders. In a stream, the most easily eroded particles are small sand grains between 0.2 mm and 0.5 mm. Anything smaller or larger requires a higher water velocity to be eroded and entrained in the flow.
