SiO₂ — Silica
>90%
Amorphous Silica Fume
High-performance micro-silica for concrete built to last.
Silpozz silica fume — over 90% SiO₂, finer than 25 microns — packs the microscopic voids between cement particles to build denser, stronger and far more durable concrete.

02 The mechanism
A super-pozzolan that fills the voids cement leaves behind.
Ordinary concrete carries microscopic gaps between cement particles. Silpozz is under 25 microns — roughly 100× finer than cement — so it settles into those voids and reacts with free calcium hydroxide to form additional binding gel.
The result is a denser, tighter molecular structure: fewer channels for water and chlorides, higher strength, and markedly better long-term durability.
- Physical void-fillingDensifies the cement matrix and refines the pore structure.
- Pozzolanic reactionConverts weak calcium hydroxide into strong binding gel.
- Sealed against corrosionBlocks the chloride ingress that attacks internal steel.

03 Where it performs
Built for demanding infrastructure.
From dams and bridges to tunnels and high-rise cores, Silpozz is engineered for the structures that cannot afford to fail.
01
Bridges & Flyovers
Stronger, lower-permeability decks and piers that resist fatigue and weathering.
02
High-Rise & Industrial
High-strength columns, cores and floors for heavy structural loads.
03
Tunnels & Underground
Low-permeability linings that hold back water and resist chemical attack.
04
UHPC & Refractory
The dense, fine-particle backbone of ultra-high-performance and heat-resistant concrete.
04 Direct from the manufacturer
Why pay an import premium to a middleman?
Most silica fume sold in India is imported from Norway, China or Bhutan and resold at a premium. Silpozz is manufactured at source — and exported worldwide — so you get the same engineered performance, direct, without the import mark-up or the wait.
Same chemistry. Same results. Manufacturer pricing and lead times.
| Parameter | Silpozz | Imported & resold |
|---|---|---|
| Source | Manufactured at source | Imported, then resold |
| SiO₂ content | >90% | ~85–95% |
| Particle size | <25 µm | Comparable |
| Lead time | Short, direct dispatch | Long, shipping-bound |
| Relative cost | No import premium | Premium + freight + duty |
| Technical support | Direct from maker | Via distributor |
