Durability Assurance for UHPC Shapes in Garden Landscapes: Technical Analysis of Qinglong UHPC Outdoor Applications

The durability of UHPC shapes in landscape gardens is ensured through triple safeguards: material modification, protective treatment, and structural design. Carbonation resistance (50-year carbonation depth ≤5mm), frost resistance (≥F300), and wear resistance (abrasion loss ≤0.5g/cm²) comprehensively outperform natural stone, with a service life of over 50 years. Surface protective treatment (fluorocarbon coating with aging resistance ≥20 years) ensures long-term aesthetics.

Verified by actual projects: a waterfront landscape project, after 5 years of use, showed no significant surface changes with 95% strength retention. Anti-slip performance (BPN ≥75) and stain resistance (dirt adhesion rate ≤5%) performed excellently. Qinglong UHPC landscape components achieve a perfect combination of durability and artistry.

Material Durability Design

Water-binder ratio ≤0.20 with high compactness. Silica fume added at 10%-15% to improve pore structure. Air-entraining agents control air content at 4%-6% to enhance frost resistance. Fiber reinforcement reduces shrinkage cracks.

Surface Protection System

Fluorocarbon coating thickness ≥35μm for UV resistance. Hydrophobic treatment with contact angle ≥110° for stain prevention. Self-cleaning coatings reduce maintenance. Regular upkeep extends service life.

Structural Waterproofing Design

Drainage slopes set at ≥3%. Multiple-layer joint sealing. Designs that avoid water accumulation. Root-puncture-resistant treatment.

Maintenance System

Annual inspection. Cleaning and maintenance every 3 years. Protection renewal every 10 years. Establishment of maintenance records.

Landscape gardens require long-lasting durability. Qinglong UHPC system solutions ensure lasting beauty over time.
