silica fume- an overview | sciencedirect topics

Silica fume is an amorphous, highly reactive pozzolan. As shown in Table 3.1, silica fume has a high content of silicon dioxide, and the X-ray diffraction analysis of silica fume shows a broad hump located at the peak of cristobalite (ACI-Committee-234, 2006). The silicon dioxide content of silica fume varies with the type of alloy that is

what issilica 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. Because of its chemical and physical properties, it is a very reactive pozzolan. Concrete containing silica fume can have very high strength and can be very durable. Silica fume is available from suppliers of concrete admixtures and, when specified, is

Apr 29, 2014 · Some examples of amorphous silica are silica fume and ground glass used in sandblasting and some countertop mixes. Amorphous silica is reactive with portland cement — sometimes in good ways, sometimes in not-so-good ways. If the particle of amorphous silica is larger than about 900 um, the particle causes ASR or alkali-silica reactivity
