Description
Overview of Fumed Silica
Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.
Features of Fumed Silica
- High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
- Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
- Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
- Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.
- Enhances free-flowing properties and stability.

Specification of Top Quality Undensified Silica Fume Microsilica Grey Powder Micro Silica Fume for Concrete from India Export
Top Quality Undensified Silica Fume Microsilica Grey Powder is a high-performance material used in concrete applications. This product comes from India and meets global standards for construction materials. The silica fume has a high silicon dioxide (SiO2) content, typically above 90%. This ensures strong chemical reactivity in concrete mixes. The particles are extremely fine, with an average size of 0.1 to 0.3 microns. This fine size allows the material to fill tiny gaps between cement particles. The result is denser, more durable concrete structures.
The product is undensified, meaning it stays in its original loose form. This makes it easy to mix into concrete without clumping. The low bulk density of 200-300 kg/m³ ensures efficient handling. The high surface area of 15-30 m²/g improves bonding with cement. This boosts the concrete’s compressive strength and reduces permeability. The material also resists chemical attacks from chlorides or sulfates. This makes it ideal for marine environments or industrial settings.
The microsilica is packaged in moisture-proof bags. Each bag holds 25 kg for easy transport and storage. Custom packaging options like jumbo bags are available for large orders. The moisture content is kept below 3% to prevent hardening during storage. Proper storage in dry conditions ensures long shelf life.
This silica fume works well in high-strength concrete, shotcrete, and precast elements. It reduces bleeding and segregation in fresh concrete. This leads to smoother finishes and faster construction times. The material complies with ASTM C1240 and EN 13263 standards. Quality checks are done at every stage, from production to delivery.
Indian exporters provide reliable supply chains and competitive pricing. The product is tested for consistency in chemical and physical properties. Technical support is available to help customers optimize mix designs. Samples can be provided for testing before bulk orders. Global clients trust this silica fume for infrastructure projects like bridges, dams, and tunnels.

Applications of Top Quality Undensified Silica Fume Microsilica Grey Powder Micro Silica Fume for Concrete from India Export
Top-quality undensified silica fume microsilica grey powder from India serves critical roles in improving concrete performance. This material is a byproduct of silicon metal production. It consists of ultra-fine particles rich in silica. The powder enhances concrete strength significantly. It fills gaps between cement particles. This creates a denser mix. The result is higher durability.
Builders use this silica fume in high-performance concrete projects. Examples include bridges, dams, and high-rise buildings. The material boosts resistance to chemical attacks. It prevents water penetration. This reduces corrosion in steel reinforcements. Structures last longer with minimal maintenance.
Industrial floors benefit from silica fume. The powder increases abrasion resistance. Surfaces withstand heavy machinery and traffic. Warehouses, factories, and parking lots use such concrete. It handles wear and tear better than standard mixes.
Marine environments require tough concrete. Silica fume helps here. Saltwater damages ordinary concrete over time. The powder reduces chloride ion penetration. This protects ports, piers, and offshore platforms.
Chemical plants need concrete resistant to acids and sulfates. Silica fume improves this resistance. Storage tanks and containment structures use it. Leaks and spills cause less damage.
Shotcrete applications rely on silica fume. The material improves adhesion to surfaces. Tunnel linings and rock stabilization projects use it. The mix stays cohesive during spraying. This reduces rebound waste.
Refractory materials incorporate silica fume. High-temperature environments demand stability. Furnace linings and kiln components last longer. The powder withstands extreme heat without cracking.
India exports this undensified silica fume globally. Suppliers ensure consistent quality. The product meets international standards. Strict testing guarantees particle size and purity. Buyers receive reliable material for specialized projects.
Silica fume reduces cement usage in mixes. This lowers carbon footprints. Sustainable construction practices prioritize such materials. Builders achieve eco-friendly goals without sacrificing performance.
Packaging options cater to bulk buyers and small-scale users. Moisture-resistant bags prevent clumping. Transport remains efficient. Delivery timelines match project schedules. Technical support is available for mix design guidance.

5 FAQs of Top Quality Undensified Silica Fume Microsilica Grey Powder Micro Silica Fume for Concrete from India Export
Undensified silica fume microsilica grey powder improves concrete strength. Here are common questions about the product.
What is undensified silica fume?
Undensified silica fume is a byproduct of silicon metal production. It is an ultra-fine powder collected from furnace gases. Unlike densified versions, it has not undergone compression. This makes it lighter and more reactive in concrete mixes.
How does it benefit concrete?
The powder fills gaps between cement particles. This creates a denser concrete structure. It increases strength, reduces permeability, and improves resistance to chemicals. Concrete lasts longer in harsh environments.
Is it different from densified silica fume?
Yes. Undensified silica fume has a lower bulk density. It is not processed to reduce volume. This means higher surface area and faster reaction with cement. Densified versions are compressed for easier handling but may require more mixing time.
How is it added to concrete?
The powder is typically mixed with cement during batching. The usual dosage is 5-10% of cement weight. Proper dispersion is crucial. Mixing equipment must ensure even distribution to prevent clumping. Workers should wear masks to avoid inhaling fine particles.
What packaging options are available?
The product is packed in moisture-resistant bags. Standard sizes include 25 kg or 1-ton bulk bags. Custom packaging is possible for large orders. Storage requires dry conditions to prevent moisture absorption.
The product meets international standards like ASTM C1240 and EN 13263. It is exported from India to global markets. Buyers receive quality certifications with shipments. Technical support is available for dosage guidance and application tips.
