MICRO SILICA

Micro Silica, Silis Fume, Mikro Silika, Silis Dumanı

Micro silica, also known as silica fume, is a byproduct of producing silicon metal or ferrosilicon alloys. It consists of very fine particles, about 100 times smaller than an average cement particle. Due to its small size and high silica content, micro silica is used in various applications across different industries. Here are some of the primary usage areas:

Usage Areas

 

1. Concrete Industry

  • High-Performance Concrete: Micro silica is used to produce high-strength concrete and improve its durability and longevity.

  • Marine Structures: It enhances the resistance of concrete to chloride penetration, making it ideal for marine environments.

  • Bridges and Highways: It is used to improve the mechanical properties and durability of the concrete used in bridges and highways.

  • Industrial Floors: Improves the abrasion resistance and reduces permeability, making it suitable for heavy-duty industrial floors.

 

2. Refractory and Ceramic Products

  • Refractory Castables: Micro silica is used to produce refractory castables with high strength and low porosity, which can withstand high temperatures.

  • Ceramics: It is used to enhance the mechanical properties and durability of ceramic products.

 

3. Oil and Gas Industry

  • Well Cementing: Used as an additive in oil well cementing to improve the strength and durability of the cement under high-temperature and high-pressure conditions.

​

​

4. Construction Industry

  • Shotcrete: Micro silica is used in shotcrete to improve its bond strength, reduce rebound, and enhance durability.

  • Repair Mortars: It is used in repair mortars to improve their bond strength and durability.

 

5. Chemical Industry

  • Silicon Carbide Production: Micro silica is used as a raw material in the production of silicon carbide.

 

6. Rubber and Plastics

  • Filler Material: It is used as a filler material to improve the mechanical properties and durability of rubber and plastic products.

 

7. Environmental Applications

  • Waste Treatment: Micro silica is used in treating industrial effluents and solid waste to reduce heavy metal contamination and improve the stability of the treated material.
