Silica Fume is a very fine pozzolanic material composed of amorphous silica produced during the production of silicon-metal or ferro-silicon alloys. It can be used in a variety of cementitious products such as concrete, grout, shotcrete and mortar. Densified silica fume has a bulk density of about 650-750 kg/m3 whereas for undensified silica fume it is about 150-300/m3.
