Bridge Girders Β· Bridge Decks Β· Wet Joints Β· Railings Β· Tunnel Segments
Prestressed UHPC main girders for 20-100m spans. Factory prefabricated, on-site lifting. Short construction period, excellent structural durability.
Used with steel box girders. Pavement thickness 35-50mm, deck stiffness improved 50%, self-weight reduced 30%.
UHPC connections between prefabricated elements. High strength, excellent durability. Solves traditional bridge deck joint weakness. 15 groups (30 beams) comparative tests: joint width can be reduced from 250-600mm to 150mm. Interface bond strength >2.5 MPa meets structural requirements.
UHPC railings impact resistance 3Γ+ normal concrete. Excellent durability, maintenance-free throughout service life.
UHPC segments with high strength and excellent waterproofing. Suitable for metro tunnels and highway tunnels. Durability 5Γ+ normal concrete.
Company provides UHPC specialized mixing equipment, pumping equipment, and steam curing equipment. Also has professional construction teams. Provides full-process technical guidance from batching, mixing to curing, ensuring UHPC material properties are fully utilized.

UHPC Prefab Slab Benefits: Increased bridge deck fatigue resistance Β· Enhanced bridge deck strength Β· Enhanced structural impact/blast resistance Β· Increased corrosion resistance
| Index | Data | Vs. Normal Concrete |
|---|---|---|
| 700 freeze-thaw cycles | Relative dynamic modulus nearly lossless | C50 loses 5.8% mass at 24 cycles |
| Impermeability Grade | >P39 (High-speed rail requires >P20) | Normal concrete P6βP12 |
| Chloride Diffusion Coefficient (28d) | 0.19Γ10β»ΒΉΒ² mΒ²/s | C50 far higher |
| Electric Flux (28d) | 98 Coulombs | JTG/T 3310-2019 requires <800C (100-year life) |
| Sulfate dry-wet cycling | Mass loss approx. 0.6%, strength continues increasing | Significantly better than normal concrete |
