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 Microsilica silica fume concrete cement additive with high SiO2 content(more than 99.8)

Microsilica silica fume is a superfine powder additive for concrete and cement. It has an incredibly high degree of silicon dioxide, exceeding 99.8% SiO2. This severe purity enhances concrete performance significantly. The particles fill microscopic gaps between concrete grains. This develops a much denser concrete matrix. Denser concrete gains higher compressive stamina. It additionally gains far better flexural strength. The enhanced density minimizes permeability dramatically. Water absorption drops considerably. Chemical resistance enhances especially. Aggressive materials like chlorides and sulfates struggle to pass through. Freeze-thaw damages resistance rises. Abrasion resistance rises also. These benefits prolong the life span of structures.

Microsilica works well in high-performance applications. Bridges take advantage of its strength improvement. High-rise buildings utilize it for long lasting structural elements. Marine structures depend on its chloride defense. Repair jobs value its bonding ability with old concrete. Industrial floorings exploit its abrasion resistance. Precast aspects achieve superior surface area top quality.

Including microsilica to concrete is straightforward. Include it during the regular blending process. The normal dose arrays from 5% to 10% by concrete weight. Precise proportioning is essential. Uniform dispersion needs expanded blending time. Workability may reduce a little. Modifications with superplasticizers typically help. Correct healing continues to be crucial. Wet curing guarantees optimum stamina development.

Applications of Microsilica silica fume concrete cement additive with high SiO2 content(more than 99.8)

Microsilica is a powerful concrete additive with very high silicon dioxide web content. This SiO2 level exceeds 99.8%. This makes it exceptionally efficient. Microsilica fragments are exceptionally great. They are much smaller sized than cement grains. This fineness fills up little rooms in between cement bits. It creates a much denser concrete mix. Water finds it harder to relocate through this thick structure. This considerably lowers concrete leaks in the structure. Less water penetration means better security for the steel support inside. Rust risks are decreased. This is important for structures subjected to harsh problems.

The high SiO2 content responds highly with calcium hydroxide in wet cement. This reaction forms added calcium silicate hydrate. This is the main binder in concrete. Much more binder suggests greater compressive toughness. Concrete with microsilica commonly shows toughness gains above 30%. It also greatly enhances the bond in between concrete and strengthening steel. This is vital for structural honesty. The concrete becomes far more resistant to chemical assault. Acids and sulfates cause less damage. This is necessary for commercial floorings, wastewater plants, and aquatic frameworks.

Including microsilica enhances concrete’s abrasion resistance. Surfaces last longer under heavy wear. This benefits factory floors, parking garages, and bridge decks. It reduces blood loss and partition during positioning. The fresh concrete is much more cohesive. Workers discover it easier to complete efficiently. It assists stop dusting and efflorescence on hardened surface areas. The last concrete looks much better and lasts much longer. Microsilica improves longevity versus freeze-thaw cycles. It decreases damage from deicing salts. This makes it valuable for roads and bridges in cool environments. Making use of microsilica expands the service life of concrete structures. Upkeep expenses decrease gradually.

5 FAQs of Microsilica silica fume concrete cement additive with high SiO2 content(more than 99.8)

What is microsilica silica fume?
Microsilica silica fume is a super-fine powder. It comes from making silicon metal or ferrosilicon alloys. This powder has very high silicon dioxide content. Our product contains over 99.8% SiO2. It gets added to concrete and cement mixes. It makes them much stronger and more durable.

Why is high SiO2 content important?
High SiO2 content matters greatly. Silicon dioxide reacts powerfully with cement. Over 99.8% SiO2 means almost pure reactive material. This high purity gives the best reaction. Impurities are almost gone. You get maximum performance improvement in your concrete.

What benefits does it give concrete?
Adding microsilica offers key advantages. It fills tiny spaces between cement particles. This creates a much denser concrete structure. Denser concrete is stronger and less porous. Water and chemicals struggle to penetrate. This improves strength, durability, and resistance to corrosion and abrasion. It also reduces bleeding and segregation.

How is it different to handle?
Microsilica needs careful handling. Its particles are extremely fine. This powder can easily become airborne. Use proper dust masks when handling it. Add it directly to the concrete mix. Sometimes it comes pre-blended with water. Follow supplier mixing instructions exactly. The water demand in your mix may increase slightly.

Is it safe?
Microsilica silica fume is safe when handled correctly. The material itself is inert. Avoid breathing the dust. Fine dust can harm your lungs. Wear appropriate protective equipment. This includes gloves, eye protection, and a respirator. Store it in a dry place. Keep containers sealed when not in use.
