SUMMARY:
Korunt is a mineral-based surface hardener with high aluminum oxide (Al₂O₃) content. Its aggregate structure provides high abrasion resistance, impact strength, and dusting protection to concrete surfaces. It offers 4-6 times higher abrasion resistance than normal concrete and compressive strength >70 MPa.
Its most important applications include factories and industrial facilities, garages, parking lots, warehouses, metro stations, helicopter and aircraft runways, and pedestrian paths.
It is applied by spreading on fresh concrete surfaces. Proper application ensures long-lasting and durable surfaces. It complies with TS EN 13813 and ASTM C779 standards.
Key Properties:
| Property | Value |
|---|---|
| Main Component | Al₂O₃ (85-95%) |
| Appearance | Dark gray/black powder |
| Density | ~2.6 g/cm³ |
| Abrasion Resistance | 4-6 times higher |
| Compressive Strength | > 70 MPa |
| Shelf Life | 36 months |
| Application Method | Broadcast on concrete surface |
CRITICAL WARNINGS:
Proper Application Timing: Must be applied when concrete begins to set (2-3 mm footprint depth). Early application causes sinking, late application causes adhesion problems.
Weather Conditions: Application temperature must be between +5 °C and +30 °C. Do not apply in windy, extremely hot, rainy, or excessively humid conditions.
Dust Control: Aluminum oxide dust inhalation may cause lung irritation. Use dust masks and adequate ventilation during application.
Joint Edges: Joint edges and heavy load areas must be reinforced with extra Korunt. These areas are subject to the highest abrasion.
Curing Period: Surface must be kept moist for 7 days after application using appropriate curing methods. This is critical for achieving full strength.
Storage: Shelf life is 36 months. Do not store in humid environments; risk of clumping and quality loss.
