Introduction
98% Densified Silica Fume is a high-performance pozzolanic material widely used in concrete, shotcrete, and refractory applications. With a SiO₂ content of up to 98% and excellent densification, it offers superior flowability, easy handling, and improved mixing efficiency. Its ultra-fine particles significantly enhance concrete strength, durability, and permeability resistance, making it ideal for bridges, tunnels, high-rise buildings, and industrial flooring. Our product meets international quality standards and ensures consistent performance for demanding projects. Choose our 98% densified silica fume for enhanced strength, long-term durability, and reliable supply.

Applications
- Water conservancy and hydropower engineering: in the anti-seepage and anti-abrasion parts, after mixing with micro-silica powder, it can greatly improve the anti-seepage, anti-cracking, anti-abrasion and anti-cavitation performance.
- The production of high-strength concrete: silica powder as admixture to make high-strength concrete, the actual application of its strength level can be achieved 100Mpa.
- Seaport engineering: concrete mixed with silica powder can improve the concrete’s anti-abrasion performance, anti-seepage performance, to prevent electrochemical corrosion of reinforcing steel.
- Traffic engineering: silica powder concrete used in highway pavement and aircraft runway, can greatly improve the early strength and wear resistance of concrete, in the maintenance and repair of highway pavement, you can advance the opening time and increase the economic benefits.
- Shotcrete: significantly improve the adhesion performance and cohesion of plastic concrete, significantly reduce the amount of rebound, increase the thickness of shotcrete once formed, shorten the construction period and save the cost of the project.
