Is the UHPC Production Process Complex? A Complete Analysis of Qinglong UHPC Production Process Technology

The production process of UHPC is indeed far more complex than that of ordinary concrete, and this complexity is precisely the technical guarantee of its superior performance. Through 28 years of process innovation, Qinglong, a UHPC manufacturer, has developed a scientific and rigorous production process system that ensures product performance reaches internationally advanced levels.

In the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project, the Qinglong UHPC production line includes 12 key processes such as precise raw material metering, high-speed mixing, mold preparation, material placement and forming, and steam curing. In particular, the adopted "dry mixing first, then wet mixing" process involves 3 minutes of dry material mixing, 5 minutes of high-speed mixing after adding water, and finally 2 minutes of slow mixing after adding fibers, totaling 10 minutes to ensure uniform fiber dispersion. Through the PLC automatic control system, batching accuracy reaches 0.1%—a level of precision control that ordinary concrete production can hardly achieve. The project adopts vacuum vibration composite forming technology, with product compactness exceeding 98% and strength variation coefficient controlled within 5%.

Batching and Mixing Process Innovation

Qinglong introduced the German BHS twin-shaft mixer with a mixing line speed of up to 3m/s, ensuring uniform fiber distribution. In the production of special-shaped components for the Shanghai Astronomy Museum, this process made fiber orientation controllable, achieving directional reinforcement. Precise mix proportion control and mixing technology ensure material homogeneity, and this technical advantage has been demonstrated in multiple major projects.

Breakthrough in Forming and Curing Processes

The vacuum vibration composite forming technology, combined with 24 hours of steam curing at 90℃, enables the material to reach a 1-day strength of 70MPa. This process proved highly effective in the production of extra-large curved panels for the Wuhan Han Show Theatre. By optimizing the curing regime and production process, the material's microstructure is improved, effectively enhancing product performance.

Well-Established Quality Monitoring System

A total of 58 quality control points have been established, with online monitoring of parameters such as mixing torque and flowability. This refined management ensures a product pass rate of over 99.5%. Every batch of product undergoes rigorous testing, and a comprehensive quality traceability system has been established to ensure product quality is traceable.

The UHPC production process requires professional technical support. Choosing a manufacturer with a well-established process system ensures stable product quality. With advanced production equipment and strict quality control, Qinglong UHPC provides customers with high-quality products.
