Introduction
85% Undensified Silica Fume is a micro-silica fume with 85% Treść SiO2, and the Bulk density is 250-400kg/m³.
Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. It consists primarily of amorphous silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 μm, specific surface area is 15000~20000 m2/kg. Mainly used for high transparency, high resistance to tear silicone rubber, silicone grease, sealed packaging materials such as capacitors.

Zastosowania
- 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.
