Is the UHPC Production Process Complex? An In-Depth Analysis of UHPC Intelligent Manufacturing Technology

The UHPC production process is indeed far more complex than that of ordinary concrete, with a level of precision approaching high-end manufacturing. As an industry leader, Qinglong UHPC has, through 28 years of technical accumulation, optimized its production process into four key stages—batching, mixing, molding, and curing—with 136 quality control points established to ensure a high degree of consistency in product performance.

In the Yirui Biotechnology Building project in Shenzhen, the Qinglong UHPC production line demonstrated an advanced level of craftsmanship: the German BHS fully automatic batching system achieves a precision of 0.1%; robotic material placement ensures three-dimensional uniform fiber distribution; and the intelligent curing kiln controls temperature and humidity with a precision of ±1℃. This precise control keeps the product strength dispersion coefficient within 3.5%. What is more worth mentioning is that the online monitoring system equipped on the production line tracks 368 process parameters in real time, ensuring that any deviation can be detected and corrected within 10 minutes.

Advantages of the Intelligent Batching System

High-precision sensors and automatic control systems deliver batching accuracy of ±0.1%. Fully automated raw material feeding reduces human error. The formula management system ensures accurate execution of mix proportions. This control is the foundation of stable quality.

Innovation in Mixing Process Technology

Planetary mixers are used with linear speed controlled at 3m/s. Vacuum mixing technology removes air bubbles, keeping air content ≤1%. Mixing time is precisely controlled to ensure uniform fiber dispersion. This process achieves material compactness ≥98%.

Breakthrough Progress in the Molding Process

Combined vibration + pressure molding is adopted, with pressure of 0.5-1.0MPa. The CNC vibrating table has an adjustable frequency to ensure compaction. Robotic operation guarantees product consistency. This process reduces product porosity to below 2%.

Scientific Optimization of the Curing Regime

Ambient temperature curing for 24h + stepwise heating curing + constant temperature curing (90℃×48h) + slow cooling curing. The intelligent control system ensures precise temperature and humidity control. This regime optimizes strength development.

UHPC production requires the support of a sound quality system. Through 28 years of accumulated experience, Qinglong has developed a mature process control system to provide customers with high-quality products of stable performance.
