Recent advances in artificial aggregate production
The increase in particle density of AAs may also be related to the density of the raw materials used. For instance, apparent particle density of carbonated BOFS aggregates produced by Morone et al. (2014) reached as high as 2900 and 3200 kg/m 3, which was probably related to the significant amount of iron content (density of about …

An Introduction to Density: Definition and Calculation
A material's density is defined as its mass per unit volume. Put another way, density is the ratio between mass and volume or mass per unit volume. It is a measure of how much "stuff" an object has in a unit volume (cubic meter or cubic centimeter). Density is essentially a measurement of how tightly matter is crammed together.
