Silica Fume
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 alloys.Silicafume 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.
