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.
What is 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.
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 …

Condensed Silica Fume – Penn State Engineering
Condensed silica fume is used as a replacement for portland cement. Silica fume can replace portland cement in the range of 9-15% by mass of cement. Since it has a high surface area, condensed silica fume increases the amount of water needed in the mixture, so it is recommended to use it along with …
