Technical Limit of Minimum Curvature Radius for UHPC Single-Curved Panels

The minimum curvature radius of UHPC single-curved panels is limited by material toughness and process capability, with premium products reaching 300mm. Through material modification and mold innovation, Qinglong Group achieved a 250mm radius in special projects, expanding design possibilities.

Material toughness is key. Increasing fiber content and optimizing the matrix enhance crack resistance. Localized reinforcement in small-radius areas prevents stress concentration. Precision molds ensure forming accuracy with a tolerance of ≤±1mm.

Process control safeguards quality. Segmented curing reduces deformation, while demolding techniques prevent damage. Through technological innovation, the limits of curvature are continually being pushed.
