Silica Fume - Norchem

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 (CSH). The benefits of this reaction can be seen in the crucial interfacial zone increasing the bond strength between concrete paste and aggregates, yielding greatly increased compressive strengths and a concrete
