Poorly graded
WebGravel typically has a void ratio about 0.4, regardless of whether it is well or poorly graded, although the void ratio can be affected by the presence of impurities, such as clay or silt. Gravel with clay has a void ratio of about 0.25, while gravel with silt can have a void ratio of 0.2 or less. Cite this Article.
