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 High Quality Microsilica SiO2 Powder Silica Fume Microsilica Grey Powder for Concrete for Export

This high quality Microsilica SiO2 Powder, also called Silica Fume, is a grey powder made for concrete. It is great for export. We make it carefully to meet top standards.

The main part is Silicon Dioxide (SiO2). Our powder has over 90% SiO2. This high purity is important. It makes the concrete much stronger and more durable. You get better performance.

The particles are very, very fine. Almost all particles are smaller than 1 micron. This fineness is key. The tiny particles fill the small gaps between cement grains. This creates a tighter concrete mix. So, concrete gets stronger and water can’t pass through easily. It lasts longer.

This powder is grey in color. It looks like a fine, dry powder. There is very little carbon in it. Low carbon is good. It means the powder works well in concrete without causing problems. You get reliable results.

Builders and concrete makers use this Microsilica powder for many jobs. It improves high-strength concrete. It is good for structures that need to last a long time. It helps concrete resist chemicals better. It makes concrete less porous. It makes concrete tougher against wear. It works well in shotcrete.

Applications of High Quality Microsilica SiO2 Powder Silica Fume Microsilica Grey Powder for Concrete for Export

High quality microsilica, also called silica fume, is a very fine grey powder. It’s made from silicon metal or ferrosilicon alloy production. This powder is mostly pure silicon dioxide (SiO2). Its particles are extremely tiny. This makes it different from regular cement or fly ash. Adding microsilica to concrete mixes brings big improvements. It makes concrete much stronger and more durable. This powder fills the tiny gaps between cement particles. It creates a denser concrete mix. Water finds it harder to penetrate this dense structure. So concrete lasts longer against weathering and chemicals.

Concrete mixed with microsilica shows much higher compressive strength. It gains flexural strength too. The bond between the concrete and steel reinforcement becomes stronger. This is crucial for building structures like bridges, parking garages, and industrial floors. These places need tough concrete. Microsilica significantly reduces concrete permeability. This stops water and harmful chemicals like chlorides from getting inside. It protects the reinforcing steel from rusting. Structures exposed to seawater or de-icing salts benefit greatly.

Using microsilica gives concrete a smoother, tighter surface finish. It reduces bleed water and minimizes surface defects. This leads to less maintenance over time. Builders value this for architectural concrete projects needing a perfect look. Our microsilica powder is processed carefully. It meets strict quality standards for export. We ensure consistent particle size and high reactivity. The powder is packed securely in moisture-proof bags. It’s ready for safe shipping worldwide. Buyers get a reliable product for demanding construction applications.

5 FAQs of High Quality Microsilica SiO2 Powder Silica Fume Microsilica Grey Powder for Concrete for Export

What is Microsilica powder? Why use it in concrete?
Microsilica powder is very fine silica. It comes from making silicon metal or ferrosilicon alloys. This powder is mostly silicon dioxide (SiO2). Builders add it to concrete mixes. It makes the concrete much stronger and more durable. The powder fills tiny spaces in the concrete. This creates a denser material. Concrete with microsilica lasts longer and resists damage better.

What are the biggest advantages of adding microsilica?
Adding microsilica brings several key improvements. First, it significantly increases the concrete’s compressive and flexural strength. Second, it greatly reduces permeability. This means water and chemicals struggle to penetrate the concrete. This improves resistance against corrosion, sulfate attack, and freeze-thaw cycles. Third, it leads to a tighter bond between the cement paste and aggregates. The result is a tougher, longer-lasting concrete structure.

How do you mix microsilica powder into concrete?
You must add microsilica correctly. Typically, it is used as a partial replacement for cement. The usual addition rate is between 5% and 10% of the cement weight. Often, the powder is pre-blended with the cement. Sometimes it is added separately during concrete batching. Good mixing is essential. It ensures the microsilica spreads evenly throughout the concrete mix. This guarantees consistent performance in the final product.

What packaging options are available for export?
We offer packaging suitable for international shipping. Our high-quality microsilica powder comes in durable, sealed bags. Common options include 500 kg or 1000 kg flexible intermediate bulk containers (FIBCs), also called big bags. We also provide smaller 25 kg polypropylene bags. All packaging is designed to keep the powder dry and safe during transport. It prevents moisture and contamination.

How is the microsilica powder shipped for export?
We follow strict procedures for export shipments. The bagged microsilica powder is securely loaded into shipping containers. We use 20-foot or 40-foot containers depending on the order size. The containers are carefully sealed. We provide all necessary shipping documentation. This includes the material safety data sheet (MSDS), certificate of analysis (COA), and commercial invoice. We work with reliable freight forwarders to ensure timely delivery.
