96% Yoğunlaştırılmamış Mikrosilika (Silika Dumanı) 96U
96% Özgürleştirilmemiş silika duman, also known as Microsilica or Condensed Silica Fume, is an ultrafine, amorphous silica byproduct generated during the production of silicon and ferrosilicon alloys. This highly reactive pozzolan is characterized by its high silica content (96%), low bulk density (250-350 kg/m³), and extensive specific surface area (15,000-30,000 m²/kg).
The remarkable properties of 96% Undensified Silica Fume can be attributed to its ultrafine particle size, yüksek saflık, and vast specific surface area. These features enable it to fill microscopic voids within the concrete matrix, thereby improving the overall density, kuvvet, and durability of the material.

Başvuru
96% Undensified Silica Fume is extensively used in the construction industry to enhance the performance of concrete and cementitious materials. Some of its key applications include:
- High-strength concrete: Its use in concrete mixtures results in improved compressive and flexural strength, making it suitable for constructing high-rise buildings, bridges, and other infrastructure projects.
- Durable concrete: The incorporation of silica fume in concrete mixtures enhances resistance against chemical attack, abrasion, and freeze-thaw cycles, making it ideal for use in harsh environments and structures with long service life requirements.
- Shotcrete and refractory materials: Due to its ability to improve bonding and cohesion, silica fume is widely used in shotcrete applications for tunnel linings, slope stabilization, and refractory materials.
- Specialty applications: Silica fume is also utilized in various specialty applications, such as oil well cementing, grouts for pre-stressed concrete, and self-compacting concrete.
