Differences Between Coarse-Grained and Fine-Grained Soil

Coarse-grained soils have 50% or less material passing the No. 200 sieve. Fine-grained soils have 50% or more material passing the No. 200 sieve. Engineering properties such as strength and compressibility of coarse-grained soil are governed by the grain-size of the particles and their structural arrangement.

The most common engineering classification system for soils in North America is the Unified Soil Classification System (USCS). The USCS has three major classification groups: (1) coarse-grained soils (e.g. sands and gravels ); (2) fine-grained soils (e.g. silts and clays ); and (3) highly organic soils (referred to as "peat").

In addition, certain soils containing shells, cinders and other non-soil materials in sufficient quantities are also grouped in this division. 1. Coarse grained Soils. Coarse grained soils are further divided into two sub-divisions: a) Gravels (G): In these soils more than 50% of the coarse fraction (+75 micron) is larger than 4.75 mm sieve size.

It should be noted that the GSD of coarse-grained materials is always changed with particle breakage. This phenomenon is unavoidable for rockfill materials when the consolidation pressure reaches 1.5 MPa, as mentioned in section 3.1. Once crushing, granular material behaviors would be dominated by not only initial GSD but also GSD evolution.
