China silica fume grade90

タイトルまたは説明

1. Introduction:
China Silica fume also called as micro silica, silica dust, which is a by-product of producing silicon metal or ferrosilicon alloys.
Silica Powder consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). Because of its fine particles, large surface area,
 and the high SiO2 content,
China 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. Main Features of China silica fume:
* High early strength
* Greater impermeability
* High ultimate compressive strengths
* Substantially greater resistance to corrosion

3. Specification of China Silica Fume 
SiO2: *0%
Bulk Density: ******0kg/m3
Moisture: 1.5%max
LOI: 3%max

4. China Silica Fume Applications:

*-China Silica Fume is used in high performance concrete, improving the intensity and performance of concrete and extend the concrete life.
