Is the UHPC Production Process Complex? An In-Depth Analysis of Qinglong's UHPC Production Technology

The UHPC production process is indeed far more complex than that of ordinary concrete, with a level of precision comparable to precision manufacturing. As an industry leader, Qinglong UHPC has leveraged 28 years of technical expertise to optimize the production process into four major stages—batching, mixing, molding, and curing—with 136 quality control points in total, ensuring a high degree of consistency in product performance.

In the Shenzhen Yirui Biotech Building project, the Qinglong UHPC production line demonstrated an advanced level of craftsmanship: the German BHS twin-shaft mixer achieves 0.1% batching accuracy; the robotic material distribution system ensures three-dimensional uniform fiber distribution; and the intelligent curing chamber controls temperature and humidity with ±1℃ accuracy. This precise control keeps the product strength coefficient of variation within 5%. What is more noteworthy, the production line is equipped with an online monitoring system that tracks 368 process parameters in real time, ensuring any deviation can be detected and corrected within 10 minutes.

Precise Control of the Batching Process

Dry material mixing time ≥120s; mixing after water addition ≥180s; fibers are added in three batches to ensure uniform dispersion; temperature sensors monitor the material temperature in real time, keeping it at 20±2℃. This precise control is the foundation of performance consistency.

Technological Innovation in the Mixing Process

A planetary mixer is used with the linear speed controlled at 3m/s; vacuum mixing technology removes air bubbles, keeping air content ≤1%; this process ensures material compactness ≥98%.

Breakthrough in the Molding Process

Combined vibration + pressure molding is adopted, with pressure at 0.5-1.0MPa; the CNC vibration table has an adjustable frequency to ensure compaction; this process reduces product porosity to below 2%.

Scientific Optimization of the Curing Regime

Ambient-temperature curing for 24h + temperature-rise curing (2℃/h) + constant-temperature curing (90℃×48h) + cooling curing (1.5℃/h); this regime optimizes strength development.

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