2007-8-31  In High Performance Concretes, silica fume is used for its chemical and physical benefits. The chemical reaction known, as the “Pozzolanic” reaction, takes place when the Portland cement is hydrated (mixed with water), producing many compounds, including calcium silicate hydrate (CSH) and calcium hydroxide Ca(OH)2. The calcium silicate hydrate (CSH) sometimes called the gel is the source of strength in concrete. When silica fume is added to fresh concrete, it chemically reacts with the calcium hydroxide Ca(OH)2 to produce additional calcium silicate hydrate

Silica Fume an overview ScienceDirect Topics

Silica fume is a by-product from the production of elemental silicon or alloys containing silicon in electric arc furnaces. At a temperature of approximately 2000°C the reduction of high-purity quartz to silicon produces silicon dioxide vapor, which oxidizes and condenses at low temperatures to produce silica fume.
