The Density of Common Rocks and Minerals

 · The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn''t as complex as you may think because water''s density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

Railroad Ballast (Rock): Specifications, Sizes, Background

Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).

Some even claim that dumping in gravel and crushed rock will result in 95 percent compaction meaning that the density of the dumped soil is 95 percent of the maximum density for that soil. In reality, the dumped density is only about 80 percent of the maximum density. The support for a buried pipe depends on the embedment soil stiffness.
