85% Unensified Silica Fume is a micro-silica fume with 85% SiO2 content, and the Bulk density is300-450kg/m3.

The main component of silica fume is SiO2, with a small amount of impurities such as C, Fe2O3, K2O, CaO, Na2O, etc. Due to its inherent characteristics, the average particle size is 0.23 um, the specific surface area is 20 m2/g, and the sieve residue of 45 um is less than 3%. By adding silica fume into concrete, the compacting, impermeability, corrosion resistance, frost resistance and other properties of concrete can be greatly improved. In concrete, the amount added is 5-10% of the cement content.

Presenting our 85% Undensified Silica Fume, a premium additive for advanced concrete applications. This product is essential for achieving superior concrete properties, ideal for modern and sophisticated construction projects.




High SiO2 content (85%) for enhanced concrete strength.

Lightweight and natural form, ensuring ease of handling and mixing.

Improves concrete's mechanical properties and longevity.

Increases resistance to harsh environmental conditions.

Eco-friendly, contributing to greener construction practices.
