Research on Durability Analysis and Improvement Strategies of UHPC Shapes for Garden Landscapes

UHPC in Garden Landscapes: When Artistic Forms Meet Century-Long Durability

In contemporary landscape design, materials are not merely the carrier of landscapes but a balance between artistic expression and durability. Ultra-high performance concrete (UHPC), with its outstanding mechanical properties and freedom of form, is becoming the ideal choice for shaping artistic landscape features. As an industry leader with 28 years of experience in the detailed design and engineering practice of UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the special requirements landscapes place on materials—they must carry the unlimited possibilities of artistic creation while withstanding long-term erosion by the natural environment. Starting from material characteristics, this article systematically analyzes the durability performance of UHPC in landscape applications and, drawing on Qinglong's full-chain technical advantages, proposes targeted improvement strategies.

Durability Challenges and Core Advantages of UHPC Garden Components

As outdoor open spaces, landscapes expose their decorative components to complex environments such as direct sunlight, rain washout, and drastic changes in temperature and humidity over long periods, and traditional materials often suffer from cracking, fading, and surface weathering. With its unique material composition—an ultra-high-strength cement matrix, a steel fiber reinforcement system, and extremely low porosity—UHPC inherently possesses a durability foundation that surpasses ordinary concrete. Experimental data show that high-quality UHPC components can reach an impermeability grade of P12 or above and withstand more than 300 freeze-thaw cycles, providing a fundamental guarantee for the long-term performance of garden landscapes. The industry standard General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC) (Plan No. 2024-0232T-JC), which Qinglong Group helped develop, further standardizes the durability indicators of UHPC in landscape applications.

Technical Pathways to Enhance the Durability of Garden UHPC Forms

In actual projects, the durability of UHPC landscape components must be achieved through the coordination of material optimization, structural design, and process control. Based on 28 years of full-chain experience, Qinglong Group has developed a three-in-one technical solution: at the material level, a customized mineral admixture system and nano-grade silica fume modification technology reduce UHPC's chloride ion penetration coefficient to below 1×10⁻¹² m/s; in structural design, BIM parametric modeling optimizes stress distribution within components to avoid stress concentration at abrupt form transitions; during production, vacuum high-pressure casting and steam curing processes ensure uniform internal compactness. In the renovation project of Century Plaza on Nanjing East Road, the landscape features created by the Qinglong team using translucent UHPC retained more than 90% of their surface gloss after three years of outdoor exposure, verifying the effectiveness of the technical solution.

UHPC Landscape Maintenance Strategies from a Whole-Life-Cycle Perspective

Durability management should not stop at product delivery; a comprehensive after-sales maintenance system is key to the long-term stability of garden UHPC. Qinglong Group has established a full-chain service model covering detailed design, manufacturing, construction and installation, and after-sales maintenance: in view of the particularities of garden landscapes, it provides regular inspection services, using 3D laser scanning technology to monitor component deformation; it has developed a dedicated protective coating system whose formulations can be adjusted for different climate zones—for example, emphasizing hydrophobicity in rainy regions and enhancing anti-aging performance in areas with strong ultraviolet radiation; and it has built a component identity traceability system that uses RFID chips to record production parameters and maintenance history, enabling precise maintenance. This "prevention-first, dynamic monitoring" maintenance philosophy has kept the GRC/UHPC landscape project at the Dongguan Women and Children's Activity Center, undertaken by Qinglong, in perfect artistic condition five years after delivery.

As a national high-tech enterprise and a participant in the development of UHPC/GRC industry standards, Qinglong Group has always believed that high-quality landscape materials should be a perfect fusion of artistic aesthetics and engineering technology. Through the deep integration of material innovation, technical optimization, and whole-life-cycle management, UHPC can not only realize designers' imaginative creative concepts but also sustain its charm through the passage of time. In the future, as the concept of green building materials deepens, Qinglong will continue to promote the upgraded application of UHPC in the landscape field, making every landscape work an artistic statement that transcends time.
