Silica fume – Wikipedia
Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) is an amorphous (non-crystalline) 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.
How Does Silica Fume Work in Concrete?
When silica fume is added to concrete, initially it remains inert. Once portland cement and water in the mix start reacting with each other (hydrating), primary chemical reactions produce two chemical compounds: Calcium Silicate Hydrate (CSH), which is the strength producing crystallization, and Calcium Hydroxide (CH), a by-product also called …
Silica Fume Topic – American Concrete Institute
Silica fume, a by-product of the ferrosilicon industry, is a highly pozzolanic material that is used to enhance mechanical and durability properties of concrete. It may be added directly to concrete as an individual ingredient or in a blend of portland cement and silica fume.

High Performance Concrete Using Fumed Silica – nbmcw.com
The combustion process creates silicon dioxide molecules, which condense to form particles. Fumed silica is being used in various fields such as pharmaceuticals, paints, adhesives and sealants, plastics, rubber and ink except for concrete. Properties of the fumed silica and silica fume have been shown in Table – 1.

Compressive strength versus fibre volume fractions for the 0.36 water–cement ratio: (a) without silica fume and (b) with silica fume. It can be seen that, for both water–cement ratio specimens (A1 and B1), the compressive strength of the fibre-reinforced specimens increased compared with those without fibres.
