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 fume is SiO2 content and fineness. The higher the content of SiO2 and the finer the fineness, the greater the pozzolanic activity, and the better modification effect on concrete.
Due to small specific gravity of silica fume, large natural inclination, bulky, easy to fly, so transportation and packaging costs are high. Henan Superior Abrasives packaging & delivery of silica fume:
10kg soluble paper bags x 84 on the pallets.
20kg soluble paper bags x 42 on the pallets.
950kg plastic woven bags x 2 on the pallets(with or without bottom output )
1000kg plastic woven bags x 2 on the pallets(with or without bottom output )
500kg plastic woven bags x 2 on the pallets (with or without bottom output )
We can also produce according to your requirement.
