How Effective Are the Products in UHPC Manufacturer Cooperation Cases? An Empirical Study of Qinglong UHPC Project Performance

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

A follow-up visit 5 years after the completion of a commercial complex project in Shenzhen showed: UHPC curtain wall panels retained over 95% of their surface color, with no cracking or hollowing, and a flexural strength retention rate of 92%. UHPC components in use for 8 years at a cultural building in Shanghai showed a color change of ΔE≤3.2, entirely within the acceptable range. These long-term data verify the product's durability. More importantly, users are satisfied with the performance and willing to choose UHPC again—such recognition is the most valuable.

Long-Term Appearance Retention

Surface color remains stable over the long term, with a 5-year color difference of ΔE≤3.0; joints are uniform and neat, with no warping or deformation; no weathering or peeling, and a high level of surface cleanliness. This performance has won user recognition.

Stable and Reliable Structural Performance

Load-bearing capacity remains stable, with an annual strength decay rate of ≤0.5%; connection joints are reliable, with no loosening; waterproofing performance is long-lasting, with no leakage issues. This stability ensures safe use.

Complete and Compliant Functionality

Meets design functional requirements, with all indicators up to standard; easy to maintain at low cost, with annual maintenance costs of only 0.5% of the construction cost; durability exceeds expectations, with a service life of over 50 years. This performance enhances user confidence.

Continuously Improving User Satisfaction

Owners are satisfied with the performance, with a satisfaction rate above 98%; they are willing to choose UHPC again, with a renewal rate exceeding 90%; they actively recommend it to other projects, demonstrating a clear word-of-mouth effect. Such recognition is the most valuable.

Long-term use performance is the best proof. We recommend focusing on projects that have been completed for more than 3 years to understand their real usage conditions. Qinglong UHPC products have been verified through long-term use, with stable and reliable performance.
