92% Densified Microsilica (Kieselschneider) 92D
92% Verdichteten Kieselsäure -Rauch (92D) is a type of silica fume that has been processed to increase its bulk density. This makes it easier to handle and transport, and can also improve its performance in concrete.
92% Densified Silica Fume is a type of microsilica that is produced as a byproduct of the production of silicon metal and ferrosilicon alloys. It is a highly reactive pozzolanic material with a high silica content of over 92% and a bulk density of around 550-700 kg/m3. The specific surface area of 92% Densified Silica Fume is very high, ranging from 20,000 Zu 30,000 m2/kg, making it an ideal additive for concrete and cement-based products.

Advantages
- Increased strength
- Improved durability
- Reduced permeability
- Increased bond strength
Anwendungen
- Hochfestes Beton: 92D is often used in high-strength concrete applications, where its pozzolanic properties can help to achieve very high compressive strengths.
- Langlebiger Beton: 92D is also used in concrete applications where durability is important, such as in marine environments or in areas with severe freeze-thaw cycles.
- Concrete with reduced permeability: 92D can be used to reduce the permeability of concrete, which can improve its resistance to water and other fluids.
- Concrete with improved bond strength: 92D can be used to improve the bond strength of concrete to steel reinforcement, which helps to improve the overall performance of the concrete structure.
