How Do Products Perform in UHPC Manufacturer Cooperation Cases?

The performance of UHPC products in actual projects is the ultimate test of a manufacturer's technical capabilities and requires comprehensive evaluation across multiple dimensions, including mechanical performance, aesthetic effect, and durability. Based on 28 years of project tracking data, Qinglong Group believes that quality UHPC products should feature stable performance, lasting aesthetics, and easy maintenance.

Mechanical performance is the fundamental evaluation indicator. In the Shenzhen Yirui Biotechnology Building project, the UHPC curtain wall panels have been in service for 3 years with a compressive strength retention rate exceeding 95% and deflection controlled within L/500. The roof system of the Hainan International Convention and Exhibition Center has withstood typhoon seasons with all connection joints intact. These actual results verify the structural reliability of UHPC products.

Aesthetic effect requires the test of time. The "Chinese red lantern" design of the Wuhan Han Show Theatre has retained its vivid red color after 5 years of use, with color difference ΔE controlled within 2.0. The light-transmitting UHPC panels at Shanghai Century Plaza still deliver stunning nighttime light and shadow effects. Through regular follow-up visits, Qinglong Group has found that the surface condition of quality UHPC products remains in good state even after 10 years of use.

Durability determines service life. In coastal high-salt-spray environments, the chloride ion diffusion coefficient of Qinglong UHPC products remains below 1.5×10⁻¹²m²/s, and rebar potential monitoring shows no corrosion risk. Projects in severe cold northern regions show no surface spalling after 300 freeze-thaw cycles. These data demonstrate the long-term durability of UHPC products.

Maintenance cost is an important consideration. Compared with traditional materials, the self-cleaning properties and stain resistance of UHPC reduce maintenance frequency. In the Nanning Wuxiang China Resources MixC One project, annual cleaning averages only once, with maintenance costs 30% lower than stone curtain walls. This low-maintenance characteristic delivers long-term economic benefits to owners.
