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.

5 FAQs 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 premium additive for high-performance concrete, widely exported from India. Here are five FAQs about the product:

**1. What is undensified silica fume, and how does it improve concrete?**
Undensified silica fume is a byproduct of silicon metal production, consisting of ultra-fine, amorphous silicon dioxide particles. When added to concrete, it fills microscopic gaps between cement particles, enhancing density, compressive strength, and durability. It reduces permeability, making concrete resistant to chemicals, water penetration, and corrosion, ideal for marine structures, bridges, and industrial floors.

**2. What are the key benefits of using microsilica in concrete?**
Microsilica improves mechanical properties like strength (up to 30% higher) and abrasion resistance. It reduces bleeding and segregation, ensuring uniform concrete consistency. Its pozzolanic reaction with calcium hydroxide produces additional cementitious compounds, increasing long-term durability. It also minimizes alkali-silica reaction (ASR), extending the lifespan of structures.

**3. How is undensified silica fume different from densified silica fume?**
Undensified silica fume is in its loose, non-agglomerated form, with particles as small as 0.1 microns. It disperses easily in concrete mixes, offering better reactivity. Densified silica fume is processed into larger granules for easier handling but may require longer mixing to break down. Undensified variants are preferred for high-precision applications requiring immediate dispersion.

**4. What packaging and storage options are available for exported silica fume?**
The product is typically packed in moisture-resistant, multi-layer kraft paper bags (25 kg or 1-ton bulk bags) to prevent contamination. Suppliers ensure airtight sealing and compliance with international shipping standards. Storage recommendations include keeping bags in dry, cool environments away from direct sunlight to maintain quality.

**5. Are Indian silica fume exports compliant with global quality standards?**
Yes, Indian undensified silica fume meets ISO 9001, ASTM C1240, EN 13263, and IS 15388 certifications. Reputable exporters provide detailed material test reports (MTRs) confirming SiO2 content (85–98%), low carbon content, and controlled particle size distribution. Indian suppliers are recognized for cost-effective pricing without compromising quality, making them a preferred choice globally.

This product is essential for engineers and contractors seeking to optimize concrete performance in demanding environments. Indian exports ensure reliability, sustainability, and adherence to technical specifications for global construction projects.
