85% Densified Silica Fume is a micro-silica fume with 85% SiO2 content, and the Bulk density is 550-700kg/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.

Introducing our top-quality 85% Densified Silica Fume, a game-changer in the construction industry. This highly effective concrete additive is designed to enhance the physical properties and longevity of concrete structures, making it an essential component for demanding construction environments.





Contains 85% SiO2, ensuring high-performance results.

Densified for efficient transport and utilization.

Significantly reduces concrete permeability, boosting durability and resistance to environmental factors.

Enhances the bonding between cement and aggregates, leading to stronger and more resilient structures.

Environmentally friendly, contributing to sustainable construction practices.
