Density of microsilica

The bulk density of silica fume depends on the degree of densification in the silo and varies from 130 (undensified) to 600kg/m3 (densified). The specific gravity of silica fume is generally in the range of 2.2 to 2.3. Condensed silica fume is essentially silicon dioxide in noncrystalline (amorphous) form. Since…
