Aggregate is a mix of rock fragments or particles that are used in construction, primarily for making concrete. It includes materials such as sand, gravel, crushed stone, and slag. The bulk density of aggregate is an important factor that determines the volume occupied by the aggregates in a given concrete mixture.

If soil has >10 % gravel or the stones are >2 cm conventional bulk density readings will be inaccurate, as most coarse fragments have bulk densities of 2.2–3.0 g/cm 3 (McKenzie et al., 2002). This is important to recognise when using bulk density measurements to calculate nutrient levels on an area basis, as an over-estimation will occur.

For gravel, the bulk density can be higher up to 130 lbs/cf as the voids are filled with sand and smaller (than 3/4") stone. We need to know the gradation of the gravel to answer this question (which has yet to have been asked. However, it is up to Mr. Guest to clarify this point and he seems to have stepped away.

If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm –3 and that of the soil as 1.20 g cm –3. Even though sand is made of rock fragments, its density is less because the porosity of sand lowers its bulk density (as shown below). (Note that the negative exponent in the units cubic ...
