PROPERTIES
- Appearance - Very fine powder
- Colour - Grey
- Odour - Odourless
- Particle Size - 45 microns
- SiO2 Silica 90 % minimum

- Pozzolanic effect: It increases the performance of concrete formations. It acts physically to optimise particle packing of concrete or mixture and chemically as a high reactive pozzolan.
- Micro filler effect: It is an extremely fine material, with an average diameter much finer than the cement. It gets well distributed in the cementatious paste, thus blocking the bleed-water channels
PACKAGING Available in 25 Kg HDPE bags or Jumbo Bags (1000 Kg)
QUALITY Adicon Micro Silica Fumes is a super pozzolan - a finely powdered material which when added to cementitious matter increases durability and gives higher strength. It complies with ASTM C1240.

Micro Silica Fumes
Enhancing Concrete with Silica FumesSilica fumes act as a high-performance additive, dramatically increasing both the compressive strength and longevity of concrete. The ultra-fine powder improves particle packing, reducing permeability and resulting in more durable, resilient structures suitable for harsh environments or demanding construction tasks.
Reliable Source for Refractory ApplicationsAs a form of acid refractory, grey silica fume powder is essential in the manufacturing of linings for furnaces, kilns, and reactors. Its high SiO2 content and strength rating between 45 and 100 make it suitable for applications requiring superior thermal and chemical resistance. Leading manufacturers and exporters in India deliver consistent quality for industrial use.
FAQs of Silica Fumes:
Q: How is silica fume powder used in construction applications?
A: Silica fume powder is commonly added to concrete mixtures to enhance strength, durability, and chemical resistance. Its fine particles fill the spaces between cement grains, resulting in denser, more robust concrete structures ideal for bridges, tunnels, and industrial floors.
Q: What benefits does silica fume provide in acid refractory products?
A: Silica fume increases the thermal stability and chemical resistance of acid refractory linings. These benefits are crucial for applications involving high temperatures and aggressive substances, such as furnaces, reactors, or kilns.
Q: Where can silica fumes be sourced from within India?
A: Silica fumes with these specific attributes can be sourced from reputable manufacturers, exporters, and suppliers across India who specialize in construction and refractory materials.
Q: When should silica fume powder be incorporated into construction projects?
A: Silica fume should be added when enhanced durability, greater compressive strength, or improved resistance to chemical and environmental attack is required, particularly in large-scale or critical infrastructure projects.
Q: What is the primary chemical composition and color of this silica fume?
A: The primary chemical component of this silica fume powder is silicon dioxide (SiO2), and it typically has a grey color, making it easily distinguishable and suitable for blending with various construction materials.
Q: What is the process of manufacturing silica fume for export and supply?
A: Silica fume is collected as a by-product from the production of silicon or ferrosilicon alloys in electric arc furnaces. The resulting fumes are then processed into a fine powder, quality-tested, and packaged for export and supply.
Q: How does using silica fume benefit the longevity of concrete structures?
A: The incorporation of silica fume significantly reduces the porosity of concrete, making it less susceptible to water intrusion and chemical attack. This leads to longer-lasting structures with lower maintenance requirements over time.
