How Do Products Perform in UHPC Manufacturer Cooperation Cases? An Empirical Study on the Practical Effectiveness of Qinglong UHPC Projects

The actual application performance of UHPC products needs to be verified through the long-term service conditions of completed projects. Qinglong UHPC establishes tracking files for finished projects, collecting long-term product performance data through regular follow-up visits and testing, providing empirical support for material applications.

A follow-up visit conducted 5 years after the completion of the Shenzhen Yirui Biotechnology Building project showed: UHPC curtain wall panels retained over 95% of their surface color, with no cracking or weathering, and a flexural strength retention rate of 96%. In the Wuhan Han Show Theater project, the red UHPC panels after 8 years of use showed a color change of ΔE≤3.2, well within the acceptable range. In a coastal project in Hainan, after 8 years of exposure to the marine environment, the carbonation depth of components was only 0.3mm, with a chloride ion diffusion coefficient of 1.2×10⁻¹²m²/s. These long-term data strongly verify the durability of UHPC and provide strong support for the promotion and application of the material.

Appearance Retention

Surface color remains stable over the long term, with no obvious staining or weathering. Joints are uniform and neat, with no deformation. This appearance has been well recognized.

Structural Performance Stability

Load-bearing capacity remains stable with no degradation. Connection joints are reliable, with no loosening. Waterproofing performance is long-lasting, with no leakage. This stability reflects the advantages of the material.

Functional Completeness

Meets design functional requirements, with convenient maintenance and low cost. Durability exceeds expectations. This performance enhances user confidence.

User Satisfaction Feedback

Owners are satisfied with the performance and willing to choose UHPC again. They actively recommend it to other projects. This recognition is the most convincing.

Long-term service performance is the best proof. Qinglong UHPC welcomes customers to visit completed projects—letting the facts speak for themselves.
