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 Micro Silica Fume,Silica Powder Be Used For Mortar/ Concrete/refractory

Micro silica fume is an ultra-fine powder. It originates from silicon steel manufacturing. This powder is primarily pure silica. The particles are unbelievably tiny. This provides it unique homes helpful in developing products.

Add mini silica to mortar. It makes the mortar much more powerful. The tiny fragments fill up the smallest rooms between sand and cement. This develops a denser mix. Denser mortar bonds much better to blocks or blocks. It additionally withstands water penetration much better. This means less fracturing and longer-lasting structures. Workers find it boosts workability as well.

Concrete advantages substantially from micro silica. Adding it significantly boosts compressive stamina. The concrete comes to be much harder and much more long lasting. It fills up the tiny gaps regular cement leaves behind. This leads to a much less permeable concrete. Less permeable concrete withstands chemicals, water, and freeze-thaw cycles much better. It safeguards steel reinforcement from deterioration. High-performance concrete often includes silica fume.

Refractory products require silica powder. Refractories deal with extreme heat. Silica fume improves these materials. It makes them denser and stronger under heats. The powder helps form strong ceramic bonds throughout shooting. This causes refractories that resist thermal shock better. They last longer in furnaces, kilns, and burners. The high silica content, generally over 94%, is key for warmth resistance.

The powder is very fine. Over 95% of fragments are smaller sized than 1 micron. This excellence is critical for its performance. The details surface is large, around 15-30 square meters per gram. It reacts swiftly with concrete. The material is usually grey or white. It can be found in compressed or undensified kinds. Manage it meticulously to stay clear of dirt.

Applications of Micro Silica Fume,Silica Powder Be Used For Mortar/ Concrete/refractory

Micro silica fume is an exceptionally fine powder. It originates from making silicon steel or ferrosilicon alloys. This powder is primarily pure silica. It is incredibly small. People utilize it to make structure products much better. It functions well in mortar, concrete, and refractory items.

Including micro silica fume to mortar aids a whole lot. It makes the mortar much more powerful. The mortar sticks much better to bricks or blocks. It lowers water leakages via the mortar joints. This makes wall surfaces extra watertight. The mortar also becomes more immune to chemicals. This is good for areas like manufacturing facilities or near the sea. The mortar lasts longer without breaking down.

Concrete gets huge improvements from micro silica fume. The little bits fill up the gaps in between concrete grains. This makes the concrete much denser. Denser concrete is a lot stronger. It likewise keeps water out much better. This secures the steel bars inside from rusting. Concrete with micro silica resists damage from salt or chemicals better. It is outstanding for bridges, parking garages, and aquatic structures. The surface area of the concrete also becomes smoother and harder. This makes it more immune to wear and abrasion.

Refractory items need to manage severe warmth. Micro silica fume is crucial right here. It aids make dense, solid refractory shapes or castables. These materials stand up much better under high temperatures. The micro silica assists create solid bonds at high warm. This makes the refractory cellular lining last much longer in heating systems or kilns. It minimizes fracturing and disintegration. This saves cash on repair work and downtime.

5 FAQs of Micro Silica Fume,Silica Powder Be Used For Mortar/ Concrete/refractory

Micro silica fume is very fine powder. Builders use it in mortar, concrete, and refractory materials. People often ask these questions.

What exactly is micro silica fume? It comes from making silicon metal or ferrosilicon alloys. Factories collect the tiny dust particles from furnace gases. This dust is nearly pure silica. The particles are incredibly small.

Why add micro silica fume to concrete? It makes concrete much stronger and more durable. The tiny particles fill the smallest gaps between cement grains and sand. This creates a denser mix. Water cannot penetrate as easily. The concrete resists chemicals better too. It also significantly improves abrasion resistance.

How much micro silica fume goes into a concrete mix? Usually builders add 5% to 10% by weight of the cement. Sometimes they use a little more or less. The exact amount depends on the project needs. Always follow the specific mix design instructions. Adding too much can make the concrete very sticky and hard to place.

Is micro silica fume safe to handle? No, it requires careful handling. Breathing in the fine dust is dangerous. It can cause serious lung disease over time. Always wear proper protective gear. Use a good respirator approved for fine dust. Wear gloves and eye protection too. Work in well-ventilated areas. Follow all safety data sheet instructions strictly.

What about the particle size? The fineness is key. Micro silica particles are about 100 times smaller than cement particles. This extreme fineness allows it to pack tightly. It fills voids effectively. This creates the dense structure needed for high performance.
