Application

Comprehensive Utilization of Silica Fume:

1. Used as cement burdening in the construction industry to improve cohesion speed, corrosion resistance, insulation and wear resistance of mixture.

2. Used for mortar and concrete to fill the gap between particles, reduce the content of Ca(OH)2, and make mortar and concrete compact and uniform.

3. Used as basic material of silicic acid synthesis for precision ceramic and high-performance powder metallurgy and important filling material of organic compound in the chemical industry.

4. Used for pesticide and soil improving variety.
