SILICA-FUME



- Silica fume is an amorphous polymorph of silicon dioxide(Sio2), silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 0.15㎛. The main field of application is as pozzolanic material for high performance concrete.
