What is Micro Silicon?

Silica fume, also known as microsilica, is a byproduct of silicon and ferrosilicon alloy production. It consists of ultrafine, spherical particles of silicon dioxide (SiO₂), typically less than 1 micron in diameter. This unique composition makes it a highly effective pozzolanic material, widely used to enhance the properties of concrete and other cementitious products.

Silica Fume – Enhancing Concrete Performance

Silica fume, also known as microsilica, is a byproduct of silicon and ferrosilicon alloy production. It consists of ultrafine, spherical particles of silicon dioxide (SiO₂), typically less than 1 micron in diameter. This unique composition makes it a highly effective pozzolanic material, widely used to enhance the properties of concrete and other cementitious products.

Applications of Silica Fume

Silica fume is utilized across various sectors, including:

High-Performance Concrete: High-Performance Concrete: Ideal for constructing buildings, bridges, tunnels, and roadways where enhanced strength and durability are essential.
Refractory Materials: Improves the performance of refractory castables, offering better sintering capabilities and high-temperature resistance.
Oil and Gas Industry: Used in well cementing to improve the mechanical properties and longevity of cementitious seals.
Fiber Cement Products: Enhances the durability and fire resistance of roofing materials, pipes, and moldings.

Benefits of Using Silica Fume in Concrete

Increased Strength: Silica fume substantially boosts both compressive and flexural strength, allowing for more robust structural designs.
Enhanced Durability: The addition of silica fume improves resistance to abrasion, erosion, and chemical attacks, extending the service life of concrete structures.
Reduced Permeability: By refining the pore structure, silica fume decreases concrete permeability, offering superior protection against water ingress and corrosion of reinforcing steel.

Key Features of Silica Fume

Ultrafine Particle Size: With particles about 100 times smaller than average cement grains, silica fume fills microscopic voids in concrete, leading to a denser and more impermeable structure.
High Reactivity: Its amorphous nature and high specific surface area facilitate a pozzolanic reaction with calcium hydroxide in cement, forming additional calcium silicate hydrate (CSH) gel. This reaction significantly enhances the strength and durability of concrete.
