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 silica fume for cement cas 68611-44-9 silica fume per kg

Silica fume CAS 68611-44-9 is a crucial product for boosting concrete performance. This product is basically extremely fine silicon dioxide powder. We get it as a spin-off from silicon metal manufacturing. Its bits are extremely tiny. This tiny dimension creates a dense framework in concrete.

Our silica fume fulfills stringent high quality requirements. The silicon dioxide content is consistently high. It normally goes beyond 90%. This high purity guarantees strong sensitivity. The material looks like a grey powder. Its mass density is rather reduced due to the little particles. You need to manage it meticulously to avoid dust.

Making use of silica fume in concrete mixtures provides huge benefits. It fills spaces in between concrete grains. This makes the concrete much denser. Water can not pass through conveniently. The concrete becomes very immune. It withstands extreme chemicals better. The product responds strongly with calcium hydroxide. This reaction creates a lot more strength-giving substances. Concrete gains significant compressive stamina. It comes to be much tougher.

This silica fume is perfect for high-performance concrete tasks. Believe bridges, dams, aquatic structures. It greatly lowers leaks in the structure. This secures reinforcing steel from rust. The fine bits enhance the bond between concrete paste and accumulations. The concrete surface finish ends up being smoother and extra resilient.

We provide silica fume per kilogram. It is available in sealed bags. We additionally offer larger bulk containers. This gives you versatility. Shop the product in a completely dry place. Keep it far from dampness. Always wear protective equipment when managing. This stays clear of dirt inhalation.

Applications of silica fume for cement cas 68611-44-9 silica fume per kg

Silica fume is a key material for improving concrete. It makes concrete much more powerful. It additionally makes concrete last much longer. This fine powder responds chemically in concrete. It loads little areas in between cement bits. This creates a denser framework. Water and chemicals find it tougher to penetrate this dense concrete. So the concrete stands up to damages better.

Concrete with silica fume holds up against rough chemicals well. This includes acids and sulfates. It is exceptional for commercial floors or chemical plants. Marine frameworks benefit considerably also. Deep sea triggers much less damage. Bridges and piers revealed to seawater require this defense. Silica fume concrete endures less from freeze-thaw cycles. Water cold inside concrete cracks it. The dense framework stops water going into easily. Roads and car park in chilly environments use this benefit.

Silica fume considerably boosts abrasion resistance. Concrete surfaces put on down slower. This is important for heavy traffic areas like factory floors or dam spillways. It provides early stamina gain. Builders can remove kinds much faster. Building and construction schedules shorten. High-rise buildings often utilize silica fume concrete for this reason. It reduces permeability dramatically. Waterproofing is naturally far better. Cellars, water containers, and tunnels attain higher water rigidity.

The pozzolanic reaction is essential. Silica fume eats excess calcium hydroxide. Calcium hydroxide damages concrete over time. Removing it develops more durable binder. This response additionally produces additional strength-giving substances. Silica fume needs excellent mixing. It requires careful enhancement to the concrete mix. Appropriate dispersion is essential for performance. Our silica fume (CAS 68611-44-9) is excellent quality. It is marketed per kilo. It fulfills rigorous market criteria. It is packaged very carefully for risk-free delivery.

5 FAQs of silica fume for cement cas 68611-44-9 silica fume per kg

What is silica fume?
Silica fume is a very fine powder. It’s a byproduct from making silicon metal or ferrosilicon alloys. Its particles are incredibly small. This powder contains mostly pure silicon dioxide. The CAS number 68611-44-9 identifies it specifically.

Why use silica fume in cement?
Adding silica fume to cement mixtures makes concrete much stronger. It significantly improves durability. Concrete becomes denser and less porous. This powder reacts chemically with cement. The reaction creates more of the strong binding material in concrete. It fills tiny gaps between cement grains.

How does silica fume improve concrete?
The ultra-fine particles fill the smallest spaces. This creates a tighter, more solid concrete structure. Water and harmful chemicals find it harder to penetrate. Concrete gains higher compressive strength. It resists damage from chemicals much better. It also reduces bleeding and segregation in the fresh mix.

Is silica fume safe to handle?
Handle silica fume powder carefully. Avoid breathing the dust. Always wear a proper dust mask. Wear gloves and eye protection. Work in well-ventilated areas. Follow the safety instructions on the product label. Store it in a dry place away from moisture.

Where is silica fume typically used?
Use silica fume for high-performance concrete projects. It’s common in bridges, parking structures, and marine piers. It’s essential for high-rise buildings needing strong support. Repair jobs often benefit from it. Use it for industrial floors taking heavy wear. It’s good for structures needing chemical resistance.
