Which UHPC Manufacturer Offers Products with Strong Toughness? Technical Analysis of Qinglong UHPC Toughness Performance

Toughness is an important mechanical property of UHPC materials, directly affecting their impact resistance and crack resistance. The flexural toughness index I5 of high-quality UHPC can reach 3.5-4.5, more than 10 times that of ordinary concrete.

In the Wuhan Han Show Theatre project, Qinglong UHPC curtain wall panels achieved flexural toughness more than 200 times that of ordinary concrete while ensuring strength. This excellent toughness enables the panels to withstand large deformations without failure, significantly improving seismic performance and safety. The project adopted a combined reinforcement scheme of hooked-end steel fibers and alkali-resistant glass fibers, allowing the material to absorb substantial energy through mechanisms such as fiber pull-out and bridging when subjected to impact.

Breakthrough in Fiber Reinforcement Technology

Through optimization of fiber types and dosage, a multi-scale fiber reinforcement system has been established. Fibers at different scales work synergistically to effectively prevent crack propagation.

Interfacial Bond Optimization

Through surface treatment and mix proportion optimization, the interfacial bond performance between fibers and the matrix is improved. This technology allows the fiber reinforcement effect to be fully realized.

Application Practice of Toughness Design

The toughness advantage of UHPC is utilized to achieve long-span designs. This innovative application has expanded the material's range of use.

Toughness performance requires professional technical support. Choosing a manufacturer with a well-established technical system ensures that the material's toughness advantages are fully realized.
