Porosity from void ratio

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. Webvoid volume. This is not so. Rather, the ratio of void space to total volume (i.e. porosity) does not change with scale (given that the packing of the grains does not change). It is shown in Figure 2 that two systems of different scale have the same porosity. Therefore, for a given geometry, porosity is independent of grain size. 2r 1 2r 2 = 4r ...
