Specific Gravity of Micro Silica

Blogs
The specific gravity of micro silica is 2.1 g/cm3~2.5 g/cm3, and the loose bulk density is 200 kg/m3~300 kg/m3. The specific gravity of silica fume is about 2/3 of that of cement, but its density is only about 1/6 of that of cement. The main quality index of micro silica…
