Silkeborgsøerne. Silica Fume Silica Fume is a byproduct of producing silicon metal or ferrosilicon alloys. One of the most beneficial uses for Silica Fume is in concrete. Because of its chemical and physical properties, it is a very reactive pozzolan.

Scancem silica fume

Silica fume, also known as microsilica and nanosilica, is a highly reactive pozzolanic filler, which is used to achieve high strength and dense concrete. Silica fume is a by-product of the manufacture of silicon and ferrosilicon alloys from high-purity quartz and coal in a submerged-arc electric furnace. Silica fume, also known as microsilica, is an amorphous polymorph of silicon dioxide, 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 150 nm. The main field of application is as pozzolanic material for high performance concrete. It is sometimes confused with fumed silica. … What is Silica Fume?
