Microsilica – Enhancing Concrete
Strength and Durability
Product Overview
Microsilica
Product Type:
Supplementary Cementitious Material (SCM)
Description:
Microsilica, also known as silica fume, is an ultrafine powder produced as a byproduct of the silicon and ferrosilicon alloy production process.
It consists of very fine spherical particles rich in silicon dioxide (SiO2).
Microsilica is a highly reactive pozzolan and is used to enhance the properties of concrete and other construction materials.

Unlocking the Full Potential of Microsilica
Key Features
High Reactivity
Microsilica is highly reactive and provides excellent pozzolanic properties, improving concrete strength, durability, and other properties.
Reduced Heat of Hydration
It helps in controlling the heat generated during the cement hydration process.
Reduced Permeability
It significantly reduces the permeability of concrete, making it highly resistant to chloride ion penetration and sulfate attack.
Enhanced Durability
Microsilica improves resistance to alkali-silica reactivity (ASR) and enhances freeze-thaw resistance.
Increased Strength
Microsilica contributes to increased compressive and flexural strength in concrete.
Environmental Benefits
Using microsilica in concrete reduces the carbon footprint, making it a sustainable choice for construction projects.
Versatile Applications
Microsilica enhances durability and strength, making it ideal for critical infrastructure and challenging environments.
High-Performance Concrete
Microsilica is used in high-strength and high-performance concrete to enhance strength, durability, and impermeability.
Self-Compacting Concrete
It is used in self-compacting concrete mixes to enhance flowability and strength.
Shotcrete
It is utilized in shotcrete applications, such as tunnel linings, to achieve high strength and resistance to harsh environmental conditions.
Pre-cast Concrete
Microsilica is valuable in pre-cast concrete products, including panels, beams, and columns.
Bridge Decks
Microsilica improves the durability of bridge decks, making them more resistant to corrosion and extending their service life.
Grouts and Repair Materials
It enhances the properties of grouts and repair materials for structural repairs.
