Recently, a concrete manufacturer from the Netherlands contacted us with a specific request. They shared their current product data sheet, a densified silica fume used in high-performance concrete—and wanted to know which of our products would be equivalent or better for their mix designs.
Their inquiry included the following details:
- Annual consumption: 200,000 kg
- Packaging: Big bags
- Order volume: Full container load
- Application: Concrete production
- Reference specifications:
- SiO₂: 90–93%
- Fe₂O₃: ≤2.0%
- Al₂O₃: ≤0.9%
- MgO: ≤1.3%
- CaO: ≤0.7%
- Cl: ≤0.15%
- SO₃: ≤0.35%
- Bulk density (densified): 600–700 g/L
- Surface area: 20–24 m²/g
- Loss on ignition: ≤2.5%
Understanding the Customer’s Application
The client produces high-strength and durable concrete where silica fume plays a key role in improving compressive strength, reducing permeability, and enhancing resistance to chemical attack. Since the Dutch market has strict quality standards (aligned with EN 13263 and ASTM C1240), they needed a product that could match those parameters precisely.
Recommended Product — HSA Silica Fume 92D
After technical evaluation, we recommended our HSA Silica Fume 92D, a densified silica fume with the following typical parameters:
| Property | Typical Value |
|---|---|
| SiO₂ | ≥92% |
| Al₂O₃ | ≤1.0% |
| Fe₂O₃ | ≤2.0% |
| CaO | ≤0.8% |
| Loss on Ignition | ≤2.0% |
| Bulk Density | 600–700 kg/m³ |
| Surface Area | 18–25 m²/g |
| Color | Gray |
| Standard | ASTM C1240 / EN 13263 |
This grade is chemically and physically very close to the customer’s MICROSILICA , ensuring smooth compatibility with their current mix design without any requalification issues.
Packaging and Logistics
We supply silica fume in:
- Densified form (92D) for ease of transport and handling.
- Big bags (1,000 kg) suitable for forklift or crane handling.
- Each container carries approximately 20 metric tons of product.
Our production facility follows ISO 9001:2015 standards and ensures consistent quality across all batches. We can also provide customized labeling or palletized shipping according to European requirements.
Quality Standards and Testing
All our silica fume products comply with:
- ASTM C1240 (USA)
- EN 13263 (Europe)
- CAN/CSA-A23.5 (Canada)
Our technical team also provides free compatibility testing with local cement and admixtures to ensure the best performance in concrete.
