What is Siica Fume? How about the applications and features?
1. Introduction:
Silica fume, also called as micro silica, silica dust, which is a
by-product of producing silicon metal or ferrosilicon
alloys.
Silica fume consists primarily of amorphous (non-crystalline)
silicon dioxide (SiO2). Because of its fine particles, large
surface area,
and the high SiO2 content,
silica fume is a very reactive pozzolan when used in concrete. The
quality of silica fume is specified by ASTM C ***0 and AASHTO M
**7.
2. Silica Fume Main Features:
* High early strength
* Greater impermeability
* High ultimate compressive strengths
* Substantially greater resistance to corrosion
