### Coarse Aggregate: Definition & Density - Video & Lesson ...

Calculating Aggregate Density. A typical range for natural coarse aggregate is 2.4 to 2.9, meaning that the coarse aggregate is 2.4 to 2.9 times the density of water. Therefore, multiplying the specific gravity and the density of water will result in the density of the aggregate itself, in units of mass per unit volume.
