Micro Silica Fume (scientific name "silica fume," Micro-silica or Silica Fume), in the smelting of ferrosilicon and industrialsilicon, silicon through the flue gas emitted by steam oxidation, the specially designed filter collected the amorphous powder like silica (SiO 2).Microsilica fume average 0.1-0.15 μ m in diameter, the size of several cement average 1.0%. Surface area for the 15-27 m 2 / g, with strong surface activity.
When it is used in concrete, it acts as a filler and as a cementitious material. The small microsilica particles fill spacesbetween cement particles and between the cement past matrix and aggregate particles. Microsilica also combines with calcium hydroxide to form additional calcium hydrate through the pozzolanic reaction. Both of these actions result in a denser, stronger and less permeable material.

Practical guidance
Microsilica is slightly hygroscopic. A slight increase in moisture content is to be expected from production through shipment and
during storage. Normally an equilibrium value in the range of 0.8-1.2% is attained depending on the ambient conditions.
Specific limit values for moisture content is restricted to material condition at the time of delivery, unless otherwise
specified, and tested according to Elkem Standard Test Methods for Microsilica, Test M-1; Water Content.
