Description

1. Introduction:
Silica fume, also called as micro silica, silica dust, it is the cement additive. This cement additive 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 

2. Cement additive Features - silica fume
* High early strength
* Greater impermeability
* High ultimate compressive strengths
* Substantially greater resistance to corrosion

3. Parameter of cement additive - Silica fume
SiO2: *2%
Bulk Density: ******0kg/m3
Moisture: 1.5%max
LOI: 3%max

4. Applications
Non-crystalline silica is widely used in high performance concrete, high intensity concrete, shotcrete concrete, dry mortar, grouting concrete, durable floor, cement, portland cement, low cement castable, fertilizer, silicate brick, firing, ironmaking, steel-making, oil drilling, rolled steel, asbestos, steam solvent, road repairing and etc.
