Difference Between Bulk Density and Relative Density of Silica Fume

Bulk density and relative density (also called true density or specific gravity) are two different physical properties of silica fume. Bulk Density Bulk density refers to the mass of silica fume per unit volume, including the spaces between particles.It represents how tightly the powder is packed. Typical range: Undensified silica fume: 150–350 kg/m³ Densified silica […]
