What is Silica Fume

Silica Fume originates from the oxidation of the SiO gas produced during the fabrication of Silicon metal, Ferrosilicon alloys and CaSi alloys in electric furnaces. The SiO2 formed is then condensed into spherical particles and recovered in bag house filters. 

 Silica Fume

Silica Fume 

is a concrete admixture that increases its strength and durability and reduces porosity and permeability.

Silica fume is a co-product from the production of silicon or ferrosilicon metal. Silica fume is a mineral admixture, a very fine powder of spherical particles that average 0.1 to 0.3 microns in diameter with a surface area of 17 to 30 m2/g.  Silica fume is used in a variety of cementitious concrete, grouts and mortars, refractory, elastomer and polymer applications. Silica fume powder is gray to off-white in color

When silica fume is used in concrete, shotcrete and repair products, it performs as a filler, improving the physical structure by occupying the spaces between the cement particles, and as a reacting chemical (pozzolanic) to create greater strength and durability to concrete.
 

Silica Fume originates from the oxidation of the SiO gas produced during the fabrication of Silicon, Ferrosilicon alloys and CaSi alloys in electric furnaces.   The SiO2 formed is then condensed into spherical particles and recovered in bag house filters.


Silica Fume consists in individual ultrafine particles of silicon dioxide with a high specific surface and an average diameter of 150nm which gives Silica Fume its high pozzolanic properties.

Silica Fume is an amorphous product.  Its color ranges from white to dark grey and is available in densified and undensified forms.
