Microsilica - an overview | ScienceDirect Topics

Silica fume, also known as microsilica, is an extremely fine noncrystalline polymorph of silica and is produced in electric arc furnaces (EAFs) as a by-product of silicon and ferrosilicon alloy production. While the first trials of silica fume as an additive in concrete were in the 1950s, at that time much of the silica fume was simply
