UHPC (Ultra‑High‑Performance Concrete) bench is a premium pre‑cast landscape seating solution for outdoor public projects.
- High Strength & Thin‑wall Design Compressive strength reaches 120‑180 MPa, 3‑5 times stronger than ordinary concrete. Enables slim‑wall, large curved, irregular artistic shapes with wall thickness only 15‑25 mm.
- Excellent Crack Resistance Mixed with steel fiber for high toughness. Modular segmented design reduces overall weight for easy transport and on‑site assembly.
- Super Outdoor Weatherability Extremely low water absorption, anti‑freeze‑thaw, UV‑resistant and salt‑spray resistant. Perfect for coastal humid environments, long service life with no chalking or sanding.
- Diverse Surface Finishes Available in plain cement, terrazzo aggregate exposed, solid integrated color, or outdoor fluorocarbon paint coating. Smooth matte texture for modern landscape.
- Low‑maintenance & Self‑cleaning Dense compact surface resists dirt and moss. Rainwater provides natural self‑cleaning effect, minimum after‑sales maintenance required.
Comparison note: GRC (Glass‑fibre Reinforced Concrete) works for complex forms yet with lower strength; UHPC delivers higher strength, thinner sections and superior weather performance at higher cost.
Application Scenarios
Suitable for outdoor commercial & public landscape projects:
- City parks, public plazas, pedestrian streets
- Shopping mall exterior, hotel courtyard, sales gallery, industrial park
- School campus, hospital outdoor areas, residential community landscape
- Waterfront zones, tourist attractions, children play zones
- Custom tree pit bench / tree surround seating, integrated planter‑bench combination
Manufacturing Process
- 3D design & modular segmentation: Split large‑size irregular benches into transportable modules, pre‑embed lifting points and connection hardware.
- Mould making: Wood mould for straight items; CNC foam master pattern + FRP mould for curved & elliptical shapes.
- UHPC material mixing: Special dry powder, quartz sand, high‑grade cement, steel fiber and admixtures under strict proportion control.
- Casting: Vibration casting / self‑compacting pouring with galvanized steel embedded parts pre‑installed inside mould.
- Curing: Static curing plus steam curing to achieve target strength and minimize shrinkage cracks.
- Demoulding, trimming & repairing for surface defects and joint positions.
- Surface finishing: polishing, terrazzo grinding, integral pigment or outdoor fluorocarbon paint coating.
- Quality inspection & wooden crate packing for shipment.
- On‑site installation: Lifting, bolt connection between modules, joint filling with UHPC repair mortar.
