Material Foundation for Complex Shapes of UHPC Double-Curved Wall Panels: The Core Code Behind Qinglong's 28 Years of R&D

Materials empower creativity — UHPC double-curved wall panels unlock new possibilities for architectural forms. With their ultimate design freedom, UHPC double-curved wall panels have become the material of choice for high-end buildings seeking complex artistic forms, and behind all of this lies the support of a strong material foundation. As a national high-tech enterprise with 28 years of UHPC R&D and production experience, Qinglong Group reveals the core material secrets behind the complex forms of UHPC double-curved wall panels, showcasing the innovative power of new building materials.

Ultra-High Plasticity: The Core Enabling Power of the Fiber Reinforcement System The primary material foundation enabling UHPC double-curved wall panels to achieve complex forms is ultra-high plasticity. Qinglong's UHPC material adopts a composite reinforcement system of high-performance steel fibers and alkali-resistant glass fibers. The fibers are uniformly dispersed in the matrix, which not only improves the material's toughness but also endows it with exceptional shaping capability. During mixing, the material exhibits excellent flowability, allowing it to fully fill the mold and precisely replicate the complex contours of the double-curved surface; after forming, the fibers bond tightly with the matrix, effectively suppressing crack formation and ensuring the integrity and stability of the double-curved form. In the Shanghai Astronomy Museum public art project, UHPC double-curved sculpture components over 3 meters in size achieved perfect forming precisely thanks to this material characteristic.

Low Shrinkage: Volume Stability Ensures Forming Precision Low shrinkage is the key for UHPC double-curved wall panels to maintain the precision of complex forms. By optimizing the cementitious material system and incorporating specialized admixtures, Qinglong keeps the drying shrinkage rate of UHPC at an extremely low level, effectively avoiding deformation caused by volume shrinkage after forming. Meanwhile, a steam curing process is adopted to accelerate the material's hydration reaction, further enhancing volume stability and ensuring that the dimensional accuracy of the double-curved wall panels matches the design. In the Guangxi New Media Center project, no two double-curved UHPC wall panels are alike, and their forms are highly complex — it was precisely by relying on the low-shrinkage material properties that precise forming and installation alignment of every panel were achieved.

High Strength Support: Thin-Section Design Expands Form Possibilities High strength performance makes the thin-section design of UHPC double-curved wall panels possible, thereby expanding design freedom. Qinglong's UHPC material achieves a compressive strength of over 150MPa and a flexural strength far exceeding that of ordinary concrete, allowing double-curved wall panels to adopt thin-section designs while realizing complex forms, reducing self-weight and structural loads. Taking the Shanghai New World Century Plaza project on Nanjing East Road as an example, the 12-square-meter extra-large UHPC double-curved light-transmitting panel is only half the thickness of conventional materials yet remains structurally stable. This is precisely the advantage brought by high-strength material properties, freeing designers from over-worrying about structural load-bearing and allowing them to focus on creative forms.

Precision Forming Technology: Collaborative Innovation of Materials and Processes The material foundation must be combined with advanced processes to fully unleash the potential of forms. Qinglong employs customized mold technology, designing dedicated steel molds or flexible molds for different double-curved forms to ensure mold precision and conformity; during production, BIM technology is used to simulate the forming process, optimize material flow paths, and prevent bubbles and defects; later-stage curing adopts precise temperature and humidity control technology to guarantee stable material performance. This collaborative innovation between processes and materials enables the complex forms of UHPC double-curved wall panels to be perfectly realized.

The complex forming capability of UHPC double-curved wall panels is the comprehensive result of material performance, R&D strength, and process innovation. With 28 years of technological accumulation, Qinglong Group continuously optimizes its material system, providing strong support for architectural creativity.
