Introducing Microsilica

What is Ferro-Silicon Based Microsilica?

Ferro-silicon based Microsilica is a fine powder created as a byproduct during the production of ferro-silicon, an alloy of iron and silicon. This powder, composed of tiny particles of silicon dioxide (SiO₂), is much finer than cement particles. When added to concrete, it fills in the gaps between cement particles, resulting in a denser and more compact concrete mix.

Why Choose Buildrock Microsilica?

• Increased Strength: The tiny particles of Microsilica bond with cement particles, creating a stronger and more durable concrete mix, perfect for high-performance projects.
• Improved Durability: Buildrock Microsilica helps your concrete resist environmental damage such as corrosion, freeze-thaw cycles, and chemical attacks, making it ideal for harsh conditions.
• Reduced Permeability: By filling microscopic gaps, Microsilica reduces the permeability of concrete, protecting the steel reinforcement inside and extending the structure’s lifespan.
• Enhanced Workability: Our Microsilica improves the workability of concrete, making it easier to mix, pour, and finish, ensuring a smooth, professional-grade result.

How Does Ferro-Silicon Based Microsilica Work?

The effectiveness of Ferro-silicon based Microsilica lies in its ultra-fine particles. When added to concrete, these particles fill the spaces between larger cement particles, creating a more tightly packed structure. This process, known as the pozzolanic reaction, occurs when Microsilica reacts with calcium hydroxide produced during cement hydration, resulting in additional calcium silicate hydrate (C-S-H), which is the compound responsible for the strength and durability of concrete.
