96% Undensified Microsilica (실리카 연료) 96유
96% 결정되지 않은 실리카 연료, 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, high purity, and vast specific surface area. These features enable it to fill microscopic voids within the concrete matrix, thereby improving the overall density, strength, and durability of the material.

응용 프로그램
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:
- 고강도 콘크리트: 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.
- 내구성있는 콘크리트: 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.
