Product Description

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

3. Microsilica Parameter
SiO2: *3%
Bulk Density: ******0kg/m3
Moisture: 1.5%max
LOI: 3%max

4. China Microsilica Applications:

*-It is used in high performance concrete, improving the intensity and performance of concrete and extend the concrete life. 
*-It is used in dry mortar, grouting concrete, improving intensity
*-It is used in durable floor, increasing flowabiliy, improving anti-corrosive
*-It  is used in cement, improving the quality than common cement
*-It is used in chemical fertilizer and prevent it from caking
*-It 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
