Colored UHPC (Ultra-High Performance Concrete) perfectly combines the material's outstanding mechanical properties with rich decorative possibilities, offering a high-end solution for modern building facades that is both expressive and durable. Producing high-quality colored UHPC places higher demands on a manufacturer's pigment selection, color matching technology, mixing processes, and surface treatment capabilities. Qinglong Group has a mature colored UHPC production line and can deliver stable, long-lasting colored UHPC products through "integral coloring" or "surface layer coloring" processes, with a color range covering various natural stone tones as well as custom colors. These products have been successfully applied to several landmark projects, including the Shanghai New World Century Plaza on East Nanjing Road.
The core of achieving long-lasting, stable color lies in "integral coloring" technology. The integral coloring process adopted by Qinglong involves uniformly mixing highly weather-resistant inorganic oxide pigments with cement, aggregates, and other materials at the batching stage, so the color is consistent throughout the body. The advantage of this process is that color becomes an inherent property of the material—even with slight surface wear, the base color will never show through, providing excellent color durability. The key lies in strict control of pigment quality: Qinglong selects top-grade inorganic pigments from internationally renowned brands such as Germany's Bayer, whose lightfastness and weather resistance reach grade 8 (the highest grade), effectively resisting UV degradation and ensuring the color remains unchanged for decades.
Precise color matching and mixing processes guarantee color uniformity. The production challenge for colored UHPC lies in avoiding color variation. Even with the same formula, subtle fluctuations in raw materials between batches, mixing duration, and curing conditions can all cause color differences. Qinglong ensures the accuracy of each batch feed through an automated precision batching system. By using forced-action mixers and optimizing the feeding sequence and mixing time, pigments and fibers achieve a molecular-level uniform distribution in the matrix. For extra-large orders, we even perform "masterbatch pre-mixing" or prepare all the coloring raw materials required for the entire project at once, fundamentally eliminating batch-to-batch color differences.
A rich variety of surface treatment processes enhance color expressiveness. After demolding, colored UHPC can achieve different gloss levels and textures through various surface treatment methods, which in turn affect the final visual effect of the color. For example, a polished finish yields vivid, saturated colors; matte or acid-washed treatments present an understated, soft texture; while sandblasting creates a texture similar to natural stone. Qinglong possesses a wide range of surface treatment techniques and experience, and can customize the most suitable surface finish for colored UHPC components according to designers' requirements. In addition, for projects with special protection requirements, a transparent fluorocarbon protective coating can be applied to further enhance color vibrancy and improve stain resistance. When choosing a manufacturer with colored UHPC production capabilities, you should visit their color sample library in person, learn about the pigment brands they use, and request photos of completed projects to ensure the color effect meets your expectations.
