What Are the New Development Directions of UHPC Technology? Material Innovation and Qinglong's R&D Achievements

UHPC technology is developing rapidly in four major directions: functional integration, low-carbon environmental protection, digital production, and expanded application scenarios. Technological innovation continues to break through traditional limitations, bringing new possibilities to the construction industry. As a national-level high-tech enterprise backed by a provincial-level R&D center, Qinglong has achieved breakthrough results in multiple technical directions, driving the upgrade of UHPC technology from “high performance” to “multi-functionality, low energy consumption, and wide application.”

Functional Integration: Extending from a single performance to multiple functions. Traditional UHPC centers on high strength and high durability, while the new direction focuses on functional integration, such as light transmission, thermal insulation, antibacterial properties, self-cleaning, and colored decoration. Qinglong's translucent UHPC technology has already been put into practice. In the Shanghai New World Nanjing East Road Century Plaza project, UHPC wood-effect translucent panels with built-in light guide rods deliver uniform light transmission and an artistic texture, winning the first UHPC Construction Engineering Innovation Award; thermally insulated integrated UHPC panels, with a composite insulation layer, achieve a thermal conductivity of ≤0.03W/(m·K), meeting building energy efficiency requirements; colored UHPC, through the combination of mineral pigments and aggregates, achieves natural effects such as imitation stone and imitation wood—the colored hollow carved panels at the Nanning Liyuan Hotel require no post-coating, and their colors remain long-lasting without fading. Functional integration upgrades UHPC from a structural material into an integrated “structure + decoration + function” material, expanding application scenarios.

Low-Carbon Environmental Protection: Green transformation and resource recycling. Guided by the “dual carbon” goals, UHPC technology is advancing toward low carbon, with core approaches including: reducing cement content, increasing the proportion of industrial solid waste, and lowering production energy consumption. The low-carbon UHPC formula developed by Qinglong uses industrial solid waste such as fly ash and slag powder to replace 20%-30% of cement and reduces silica fume usage by 15%, cutting carbon emissions by 25% compared with traditional UHPC; this technology has obtained an invention patent and passed the Guangdong Province scientific and technological achievement appraisal. On the production side, Qinglong's automated production lines adopt energy-saving equipment, and its intelligent curing kilns reduce energy consumption by 30% through waste heat recovery. In terms of recycling, discarded UHPC components can be crushed and reused as aggregates, with a recycling rate of 80%, achieving resource circulation. Low-carbon technology makes UHPC better meet green building requirements, earning policy support and market recognition.

Digital Production: Upgraded precision, efficiency, and intelligent control. Digital technology is deeply integrated into UHPC production, covering the entire process of design, molds, manufacturing, and testing. On the design side, Qinglong adopts BIM + parametric design to achieve precise segmentation and optimization of complex components—for the Shanghai Astronomy Museum sculpture project involving pieces over 3 meters, Rhino + Grasshopper parametric design ensures geometric precision. On the mold side, the application of CNC engraving and 3D printing shortens the production cycle of complex molds by 50%, with precision reaching ±0.5mm. On the production side, intelligent batching, automated mixing, and online monitoring systems keep the entire production process under control, improving fiber dispersion uniformity by 40%. On the testing side, non-destructive testing technologies (ultrasonic and radar detection) replace traditional destructive testing, enabling rapid product quality screening. Digital production increases UHPC production efficiency by 30% and keeps the defect rate within 1%, providing a guarantee for large-scale mass production.

Expanded Application Scenarios: Cross-sector integration and special-function breakthroughs. UHPC technology is extending to more specialized scenarios, such as extreme environments (severe cold, high salt spray), the new energy sector, and marine engineering. The frost-resistant UHPC developed by Qinglong for severely cold regions has a frost resistance grade of ≥F500 and is suitable for low-temperature areas such as Northeast and Northwest China; the UHPC designed for high salt spray environments improves chloride ion penetration resistance by 50% through the addition of rust inhibitors and optimized compactness, making it suitable for coastal bridges and offshore platforms; in the new energy sector, UHPC wind power foundations, with their high strength and fatigue resistance, replace traditional concrete and extend service life to 25 years; in addition, UHPC is also used in emerging scenarios such as 3D-printed buildings and emergency disaster relief components—Qinglong's 3D-printed UHPC components have completed laboratory verification, with printing precision reaching ±2mm.

The new development directions of UHPC technology essentially meet the market demand for high-quality, low-energy-consumption, multi-functional building materials. Through continuous R&D and project practice, Qinglong has achieved substantive results in all four major directions—functional integration, low-carbon environmental protection, digital production, and scenario expansion—both leading the industry's technological upgrade and providing customers with more valuable products and solutions. In the future, as the technology continues to mature, UHPC will see innovative applications in more fields and become a core growth point of the building materials industry.
