Microsilica‘s Info
Microsilica 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.
Microsilica's benefits
Dense castables
Improved flow
Hot strength
Strength during heat-up
Areas of application
Steel and foundry: Blast furnace troughs and runners, ladle linings, sliding gates, etc.
Cement: Preheater linings, lining in the chain system and lining of in- and outlet zones of rotary kilns
Glass and ceramics: Kiln furniture

Practical guidance
Storage
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.
Dosage
In order to give best results, Elkem Microsilica should be used in quantities of 3-8 wt% of the total dry mix. When optimum
particle packing is applied, the water demand is normally 4 - 5 % of the total dry weight, depending on the microsilica quantity.
Deflocculants
For microsilica to have the desired flow enhancing properties, it is vital that it is well-dispersed. It is generally advised to
use a deflocculant. Among a variety of different additives available, we highly recommend to use SioxX in microsilica containing
castables.
