Research and Analysis on the Durability of UHPC Shapes in Garden Landscapes

In contemporary landscape design, material selection not only concerns aesthetic presentation but also directly affects a project's long-term quality and maintenance costs. As an industry leader with 28 years of experience in detailed design, manufacturing, construction and installation, and after-sales maintenance of UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the core value of durability for landscape projects. This article systematically analyzes the durability advantages of UHPC shapes in landscape applications from three dimensions—material properties, environmental adaptability, and engineering practice—providing a professional reference for designers and owners.

UHPC (Ultra-High Performance Concrete), as an innovative building material, derives its durability from its unique material composition and microstructure. Compared with traditional concrete, UHPC achieves a compressive strength of over 150MPa and a flexural strength exceeding 30MPa through optimized particle grading and the addition of steel fibers or ultra-fine silica fume, while featuring extremely low porosity (typically less than 1%). This dense structure not only endows UHPC with excellent impermeability, effectively resisting erosion from rainwater and dew in landscape environments, but also significantly reduces the risk of chloride ion penetration, preventing steel reinforcement corrosion. 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 participated in formulating, further standardizes the performance indicators of UHPC in landscape components, providing authoritative assurance for durability.

The complexity of landscape environments poses severe tests on material durability, yet UHPC shapes excel in weathering resistance, freeze-thaw resistance, and wear resistance. In southern regions with intense sunlight, the high density of UHPC reduces UV-induced surface aging; in cold, snowy areas, its outstanding freeze-thaw cycle resistance (strength loss rate below 5% after 300 freeze-thaw cycles) effectively avoids the cracking problems of traditional materials. Take the translucent concrete project of the Nanjing East Road Century Plaza renovation undertaken by Qinglong Group as an example: the project adopted UHPC translucent components, which maintained good surface color and structural integrity after 3 years of outdoor exposure, confirming the durability advantages of UHPC under complex climatic conditions. Moreover, UHPC's tolerance to acidic and alkaline soils and plant root exudates makes it particularly suitable for landscape components in direct contact with soil, such as flower beds and tree pits.

From an engineering practice perspective, the durability of UHPC shapes is also reflected in full-chain control spanning detailed design, production processes, and installation and maintenance. As a National High-Tech Enterprise, Qinglong Group has a provincial-level R&D center and a comprehensive quality control system, and applies advanced processes such as automated material distribution and steam curing in the production of UHPC landscape components to ensure stable product performance. During installation, BIM technology and 3D scanning positioning enable precise component assembly, reducing the risk of cracking caused by installation stress. To meet the after-sales maintenance needs of landscape projects, Qinglong has established a nationwide service network that provides regular inspections and maintenance recommendations, such as renewing surface sealants to further extend the service life of UHPC components. This full-chain service model of "detailed design - manufacturing - construction and installation - after-sales maintenance" provides systematic assurance for the long-term durability of UHPC shapes.

As landscape design develops toward personalization and artistic expression, UHPC, with its outstanding durability and shape freedom, is becoming an ideal alternative to traditional stone and concrete. Backed by 28 years of industry experience, Qinglong Group will continue to promote innovative applications of UHPC materials in the landscape field, helping create landscape works that combine aesthetic value with long-term performance. Whether artistic benches in commercial complexes or free-form sculptures in municipal parks, UHPC shapes will inject lasting vitality into urban landscapes with their "ever-new with age" character.
