Silpozz Micro-Silica or Silica Fume

 

Welcome to Silpozz Micro-Silica | Silica Fume 

Silpozz is a very good super-pozzolan.Silpozz is an organic micro-silica / amorphous silica also known as Silica Fume, with silica content of above 90% having particle size of 25 microns mostly. Our product – Silpozz can be used as a admixtureig way to make special concrete mixes. There is a growing demand in a bfor fine amorphous silica in the production of special cement and concrete mixes. This market is currently filled by silica fume or micro silica , being imported from Norway, China and also from Bhutan . Due to limited supply of silica fumes in India and the demand being high, the price of silica fume has risen to as much as US$ 550 / ton in India.

TECHNICAL SPECIFICATIONS :

Silica Fume or Micro-Silica Application

The particle size of the cement is about 35 microns. There may be formation of void in the concrete mixes, if curing is not done in properly. This reduces the strength and quality of the concrete.

Our product – Silpozz micro-silica (silica fume) – which is rich in reactive silica is finer than cement having most particles size of 25 microns and below, so much so that it fills the interstices in between the cement in the aggregate. That is where the strength and density comes from. And that is why it can reduce the amount of cement in the concrete mix besides improving strength and quality of concrete.

Application Areas:

  • High performance concrete
  • High strength, low permeability concrete
  • Concrete in marine environments
  • Industrial flooring
  • Water tanks and sumps
  • Chemical storage tanks
  • Basements and sewerage pipelines
  • Refractory mixes etc.
 
Micro-Silica Advantages

Micro-Silica Advantages

Here are some of the top advantages of Silpozz Micro-Silica or Silica Fume that you can expect using Micro Solica or Micro Silica Fume:

For Strength:

Silpozz micro-silica is used in place of silica fumes or micro silica at a much lower cost, without compromising on the quality aspect. Adding Silpozz to the concrete mix even in low replacement will dramatically enhance the workability, strength and impermeability of concrete mixes, while making the concrete durable to chemical attacks, abrasion and reinforcement corrosion, increasing the compressive strength by 10% – 20%.

For water proofing:

Silpozz has excellent water resistance (impermeability) properties and is used in waterproofing compounds to give amazing results. It reduces the water penetration by as much as 60%.

For Better Concrete in Marine environment:

Adding Silpozz to concrete and paints helps to reduce the chloride ion penetration by as much as 50% into the structure, thus improving life of the building.

For Lower heat of Hydration:

Adding Silpozz to concrete lowers the heat of hydration by as much as 30% and prevents formation of cracks during casting.

For Better Concrete in Marine environment:

Adding Silpozz to concrete and paints helps to reduce the chloride ion penetration by as much as 50% into the structure, thus improving life of the building.

For Lower heat of Hydration:

Adding Silpozz to concrete lowers the heat of hydration by as much as 30% and prevents formation of cracks during casting.

FAQs about Silpozz Micro-Silica

Silpozz is an organic micro-silica (amorphous silica) with over 90% silica content. It is a fine powder with particles typically under 25 microns in size. Silpozz is primarily used as an admixture to enhance concrete mixes, improving their strength, durability, and impermeability.

  • Silica (SiO2): >90%
  • Humidity: <2%
  • Particle size: < 25 microns
  • Colour: Grey
  • Loss on ignition at 800°C: <4%
  • pH value: 8.0

Silpozz micro-silica fills the interstices between cement particles in concrete, enhancing strength and density. It reduces the amount of cement required in mixes, improves workability, and boosts concrete’s overall quality.

  • High-performance concrete
  • High-strength, low permeability concrete
  • Concrete used in marine environments
  • Industrial flooring
  • Water tanks and sumps
  • Chemical storage tanks
  • Basements and sewerage pipelines
  • Refractory mixes
  • Cost-Effective: Silpozz is a more affordable alternative to imported silica fume from countries like Norway, China, and Bhutan.
  • Enhanced Concrete Strength: It improves compressive strength by 10-20% even at low replacement levels.
  • Waterproofing: Silpozz significantly reduces water penetration by up to 60%, enhancing the impermeability of concrete.
  • Durability in Marine Environments: It reduces chloride ion penetration by 50%, making concrete more resistant to marine conditions.
  • Lower Heat of Hydration: By lowering the heat of hydration by up to 30%, Silpozz helps reduce cracking during concrete curing.

The demand for high-quality, fine amorphous silica like Silpozz is increasing as the construction industry requires stronger, more durable, and waterproof concrete. Traditional silica fume supply is limited in some regions, driving up prices, which makes affordable alternatives like Silpozz more attractive.

Silpozz enhances concrete’s resistance to chemical attacks, abrasion, and reinforcement corrosion. Its water-resistant properties also prevent water penetration, making it highly effective for structures exposed to harsh environments such as marine conditions and industrial settings.

Silica fume prices in India can rise as high as US$ 550 per ton due to limited supply. Silpozz, as a local and cost-effective alternative, provides similar benefits at a much lower cost.

Yes, Silpozz can also be used in refractory mixes, paints, and coatings to enhance their performance, particularly in environments exposed to high temperatures or chemical aggression.

Silpozz lowers the heat of hydration in concrete by as much as 30%, reducing the potential for thermal cracking during the curing process.

Industries that require high-strength, durable concrete for demanding applications benefit the most. These include:

  • Construction (especially for marine, industrial, and infrastructure projects)
  • Chemical storage and water containment
  • Flooring and sewage systems
