How Do Products Perform in UHPC Manufacturer Cooperation Cases? An Empirical Study of UHPC Engineering Performance

The actual application performance of UHPC products needs to be verified through long-term usage conditions 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 to a commercial complex project in Shenzhen five years after completion showed that the surface color retention of UHPC curtain wall panels exceeded 95%, with no cracking or hollowing, and a flexural strength retention rate of 92%. For UHPC components that have been used for eight years in a cultural building in Shanghai, the color change was ΔE≤3.2, fully 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—this 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; there is no weathering or peeling, and surface cleanliness is high. This performance has earned 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 Functional Performance

Meets design functional requirements, with all indicators up to standard; maintenance is easy and low-cost, with annual average maintenance expenses at only 0.5% of construction cost; durability exceeds expectations, with a service life of over 50 years. This performance strengthens user confidence.

Continuously Rising 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. This recognition is the most valuable.

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