Density of Rocks and Soils

2021-7-12 · For example, sandstone (characteristically quartzose) has a typical dry bulk density of 2.0–2.6 g/cm 3, with a porosity that can vary from low to more than 30 percent. The density of quartz itself is 2.65 g/cm 3. If porosity were zero, the bulk density would equal the grain density.

Aggregate Base Density Data

 · The (150-180) density data comes from a "Design and Control of Concrete Mixtures" book and appears to refer to the "particle" density of aggregate. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3).
