Is the UHPC Production Process Complex? An In-Depth Analysis of Its Technical Challenges and Production Workflow

In the field of contemporary architecture, Ultra-High Performance Concrete (UHPC) is becoming the “new favorite” of landmark buildings thanks to its outstanding mechanical properties and artistic expressiveness. However, the complexity of its production process often deters industry professionals. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group will provide an in-depth analysis of the “precision code” of UHPC production from the perspectives of technical challenges and the entire process.

I. UHPC Production: The Dual Challenge of Materials Science and Engineering Technology

UHPC's “ultra-high performance” stems from its unique material composition and microstructure, which also determines the complexity of its production process. Compared with ordinary concrete, UHPC requires strict control over the particle gradation of raw materials—for example, quartz sand must undergo multi-stage sieving to achieve micron-level precision, and the aspect ratio and dispersion of steel fibers directly affect the crack resistance of components. Through 28 years of process refinement, Qinglong Group has established a full-process quality control system from raw material selection to mix ratio optimization, ensuring the homogeneity of every batch of materials.

II. Production Process Decoded: Precision Control from Laboratory Formula to Engineering Implementation

The UHPC production process can be summarized into four core stages: “precise batching—efficient mixing—mold systems—curing techniques.” In the batching stage, Qinglong adopts an automated metering system with errors controlled within ±0.5%; the mixing stage requires twin-shaft forced mixers to achieve nano-level material dispersion and prevent steel fibers from clumping; for molds, when it comes to components with complex shapes, Qinglong introduces BIM parametric design and CNC machining technology to ensure mold precision at the 0.1mm level. Notably, the UHPC curing process requires the coordination of steam curing and natural curing—Qinglong's original “gradient temperature-controlled curing method” enables components to stably exceed 150MPa in 28-day compressive strength.

III. Solving Industry Pain Points: Technical Empowerment through Qinglong's Full-Chain Services

UHPC production currently faces three major industry pain points: first, the forming challenges of complex components; second, stability control in large-scale production; and third, the balance between cost and performance. As a national-level high-tech enterprise, Qinglong has built solutions through 58 patented technologies: for irregular components, it adopts 3D scanning and 3D printing pre-forming technologies; intelligent production lines achieve a stable daily output of 300㎡ of components; and in material formulas, dedicated mineral admixtures have been developed to replace part of the cement, reducing overall costs by 15%. This technical accumulation is precisely what gives Qinglong the confidence to undertake benchmark projects such as the translucent concrete project at Century Plaza on Nanjing East Road.

IV. Future Trends: Collaborative Innovation of UHPC with GRC/GRG/GRP

With the diversified development of architectural aesthetics, a single material can no longer meet complex design needs. Qinglong Group takes UHPC as its technical core, integrating the shaping freedom of GRC, the acoustic performance of GRG, and the lightweight advantages of GRP to form an “UHPC+” composite system. For example, in the Dongguan Women and Children's Activity Center project, the combination of UHPC and GRC achieved both the structural safety of long-span components and the artistic effect of curved-surface decoration. This integration capability across a full material system is precisely Qinglong's core competitiveness as an industry leader.

The UHPC production process is both a technical barrier and a quality threshold. Qinglong Group's 28 years of deep industry experience have not only unlocked the technical code of material production, but also built full-chain service capabilities from detailed design to after-sales maintenance. For architects and developers pursuing ultimate performance and aesthetic expression, choosing a UHPC manufacturer with full-process control is the key to project success. In line with Qinglong's mission of “Creating Beautiful Architecture,” we will continue to drive the upgrading of building materials through technological innovation, contributing more “impossible” engineering marvels to the industry.
