How to Judge Whether a UHPC Manufacturer's Formula Technology Is Advanced?

In the field of architectural decoration materials, UHPC (Ultra-High Performance Concrete), with its outstanding mechanical properties and design plasticity, is becoming the material of choice for high-end construction projects. However, the technical levels of UHPC manufacturers on the market vary widely, and how to judge whether their formulation technology is advanced has become a core concern for designers, owners, and purchasers. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze the selection criteria from three dimensions: material performance, technological innovation, and engineering practice.

Advanced UHPC formulation technology is first reflected in breakthroughs in core performance indicators. High-quality UHPC must combine high strength (compressive strength ≥150MPa), high toughness (fracture energy ≥30kJ/m²), and excellent durability, which depends on precise control of raw material gradation and fiber dispersion technology. For example, by optimizing the proportions of active admixtures such as silica fume and ultra-fine quartz sand, combined with its self-developed steel fiber dispersion process, Qinglong Group has raised the flexural strength of its products to over 25MPa and achieved an impermeability grade of P12, meeting long-term service requirements in extreme conditions such as marine environments and severely cold regions. Industry companies such as Nanjing Beilida also stand out in high performance indicators, jointly pushing forward the boundaries of UHPC technology.

The advancement of formulation technology must also be verified through innovative application scenarios. Traditional UHPC is mostly limited to structural components, while advanced formulations can achieve a fusion of function and aesthetics. In the renovation project of Century Plaza on Nanjing East Road, in which Qinglong participated, light-transmitting UHPC panels were adopted. By adjusting the ratio of the cement matrix to light-transmitting aggregates, the components achieved a light transmittance of 15%-20% while maintaining structural stability, and this technology won the Silver Award of the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award. In addition, in the Dongguan Women and Children's Activity Center project, the application of GRC and UHPC composite components demonstrated the formulation design capability of multi-material synergy, confirming the practical value of the technology.

Judging a manufacturer's technical strength also requires examining its R&D system and its participation in standard-setting. As a national high-tech enterprise, Qinglong Group has a provincial-level R&D center, has obtained 58 patents in total, and has led or participated in the formulation of multiple industry standards, including "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)." This closed-loop capability of "R&D-Practice-Standardization" is an important guarantee of advanced formulation technology. In contrast, manufacturers that lack their own R&D teams or rely solely on purchased formulations find it difficult to meet the customization needs of complex projects.

Choosing a manufacturer with advanced UHPC formulation technology is essentially choosing full-chain technical service capability. From parametric modeling in the detailed design stage, to automated casting in the production process, and then to whole-life-cycle management of installation and maintenance, Qinglong's integrated "Design-Production-Construction-Maintenance" service ensures the effective implementation of formulation technology. For designers and owners, examining the manufacturer's project case library, the standardization of its test reports, and the response speed of its technical team is far more critical than simply comparing material prices—after all, the value of UHPC lies not only in the material itself, but also in the technical support and innovation capability behind it.
