How Is the UV Aging Resistance of Outdoor UHPC Panels? Qinglong UHPC Weatherability Research

Outdoor UHPC panels offer excellent UV aging resistance. After 5000 hours of xenon lamp aging (equivalent to 25 years of natural exposure), the color difference is ΔE≤3.0 with strength retention ≥90%. This is attributed to their dense structure and inorganic material properties, making it difficult for UV rays to penetrate and degrade the panels.

In accelerated aging tests, Qinglong UHPC panels showed no surface chalking after 10000 hours of UV aging, with a mass loss rate ≤0.1%, far superior to polymer materials. Actual project tracking shows that UHPC curtain wall panels in use for 10 years maintain 95% surface color retention with no strength loss. The UHPC curtain wall of a landmark building has remained like new after 10 years of intense UV radiation.
