UHPC Production Process Explained: The Standardization and Refinement Behind the Complex Workflow

"UHPC's ultra-high performance stems from millimeter-level control and process innovation across the entire production process." For UHPC, the production process is the core bridge connecting raw materials and final products, and its complexity directly determines product performance and application results. As an industry benchmark integrating detailed design, manufacturing, and construction installation, Qinglong has developed a UHPC production system that combines standardization and refinement through 28 years of technical accumulation.

#Key Production Stages: Rigorous Control of Four Core Processes ????

- Precise Batching and Mixing: UHPC batching errors must be controlled within ±1%. Qinglong uses a fully automated metering system to achieve precise proportions of aggregates, cementitious materials, fibers, and admixtures. The mixing process is divided into two stages—dry mixing and wet mixing—with low-speed mixing ensuring uniform fiber dispersion and preventing clumping. This is a key step in ensuring the stable performance of the translucent UHPC components for Shanghai New World Plaza.

- Casting and Molding: Mold casting is carried out according to product shapes, with mold design for complex components incorporating BIM technology. Qinglong has a production capacity of 600,000 square meters and is equipped with a dedicated mold workshop, enabling precise molding of various shapes including flat panels, double-curved surfaces, and hollow-out patterns. Complex components for projects such as the Wuhan Han Show Theatre were all produced through this process.

- Curing and Hardening: High-temperature steam curing or standard curing is adopted to ensure complete hydration. Qinglong has established a professional curing workshop and customizes curing curves according to different product characteristics, allowing UHPC strength to reach design requirements within the specified cycle and ensuring no strength loss in components for over 20 years.

- Finished Product Testing: Each batch of products must undergo multiple tests including compressive strength, flexural strength, and durability. Qinglong has a well-equipped testing laboratory, with testing methods covering the entire process from raw materials to finished products, in compliance with national and industry standards.

#Process Complexity: Balancing Technical Barriers and Large-Scale Production

The complexity of the UHPC production process is reflected in two core requirements: "precision" and "stability". On one hand, stages such as fiber dispersion and water-binder ratio control place extremely high demands on equipment and technology, which ordinary manufacturers struggle to overcome; on the other hand, large-scale production requires resolving the contradiction between mold reuse, production efficiency, and quality consistency. Through technological innovation, Qinglong has standardized complex processes, ensuring both product quality and efficient delivery. Its production base in Nanning, Guangxi can meet the batch supply demands of large-scale projects.

From laboratory formulas to industrial production, upgrading UHPC processes depends on long-term technical accumulation and practical refinement. Building on 28 years of industry experience, Qinglong continuously optimizes its production processes, making complex procedures controllable and replicable, providing solid assurance for the application of UHPC in various high-end construction projects.
