product introduction
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.
