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
3. Grade*2 Silica Fume Parameter
SiO2: *2%
Bulk Density: ******0kg/m3
Moisture: 1.5%max
LOI: 3%max
4. Grade*2 Silica Fume Applications:
*-Silica Fume is used in high performance concrete, improving the
intensity and performance of concrete and extend the concrete
life.
*-Silica Fume is used in dry mortar, grouting concrete, improving
intensity
*-Silica Fume is used in durable floor, increasing flowabiliy,
improving anti-corrosive
*-Silica Fume is used in cement, improving the quality than common
cement
*-Silica Fume is used in chemical fertilizer and prevent it from
caking
*-Silica Fume is used in silicate brick
*-As a additive material for resin and another high polymer
material and subsitute for black,
silicon dioxide, talc stone, asbestos, steam solvent and tec
