Silica fume, also known as microsilica, it is a very fine pozzolanic material, composed of amorphous silica produced byelectric arc furnaces as a byproduct of the production of elemental silicon or ferro silicon can be used in a variety of cementitious products such as concrete,grouts,and mortars as well as elastomer, polymer,refractory, ceramic and rubber applications.

Chemical properties of silica fume: — Amorphous; — Silicon dioxide > 85%; — Trace elements depending upon kind of fume. Silica fume particles are incredibly small, with over 95 percent of the particles being less than 1 um (a single micrometer). Size is extremely important for both the chemical and physical gifts of microsilica in concrete.
