Microsilica - Product
Microsilica
Microsilica, also known as Silica Fume, is a byproduct of the silicon and ferrosilicon production process. It consists of very fine, amorphous silicon dioxide (SiO₂) particles that are collected from the flue gases of electric arc furnaces. Microsilica is used as a supplementary cementitious material in concrete and other applications due to its high pozzolanic reactivity and particle fineness.
- Product Category: Abrasive & Material
- Key Features:
- Fine Particle Size: Microsilica particles are extremely fine, typically ranging from 0.1 to 1.0 micrometers, providing a high surface area for chemical reactions.
- High Pozzolanic Reactivity: Reacts with calcium hydroxide in cement to form additional calcium silicate hydrate, improving the strength and durability of concrete.
- Enhanced Durability: Improves the durability and resistance of concrete to environmental factors such as moisture, chemicals, and high temperatures.
- Low Bulk Density: The fine particles result in a low bulk density, which can enhance the workability and consistency of concrete mixtures.
Applications:
Concrete: Used as a supplementary cementitious material in concrete to enhance strength, durability, and workability. Commonly applied in high-performance concrete, self-compacting concrete, and in applications requiring resistance to aggressive environments.
