From March 13th to 15th, the Second National Conference on the Technological Development and Innovative Application of Ultra-High Performance Concrete (UHPC) was successfully held in Wuhan. With the core theme of "Cultivating New Productive Forces and Promoting the High-Quality Development of UHPC", the conference set up four sub-forums and gathered more than 300 experts, scholars, enterprise representatives, and industry practitioners from across the country. Ganzhou Daye Metal Fiber Co., Ltd., as a representative enterprise in the field of metal fiber materials, was invited to participate in the conference and deeply engaged in technical exchanges, showcasing its technological achievements in the field of UHPC reinforcing materials.

The Conference Focuses on the Innovation of the Entire UHPC Industry Chain

Through four sub-forums, this conference systematically sorted out the latest progress of UHPC technology:

1、Structural Innovation and Application

The sub-forum focused on the engineering practices of UHPC in the infrastructure field. Chief Engineer Sun Xiangdong from Guangdong Provincial Transport Planning and Design Institute proposed the UHPC thin-layer reinforcement technology, which has achieved a 30% increase in flexural strength in bridge repairs. Associate Researcher Xu Xiaoqing from Tongji University discussed the application of GFRP bars combined with UHPC in wind turbine towers, providing a new solution for offshore anti-corrosion structures.

2、Architectural Innovation and Application

In the Hefei Art Museum project, UHPC hanging panels achieved the unity of artistic modeling and structural performance through refined prefabrication. Shanghai Sandali Company used the UHPC integrated technology in the South Bund Sanitation Building project, shortening the construction period by 40%, highlighting the advantages of industrialized construction.

3、Molding and Construction Technology

The Ultra-High Performance Shotcrete (SUHPC) technology developed by Hunan Renjianbaogu Company, combined with intelligent equipment, reduced the rebound rate to below 8%. Director Gao Liqiang from China Railway Bridge Bureau showed the construction system of lightweight and high elastic modulus UHPC bridge decks, reducing the self-weight of the bridge by 15%.

4、Material Performance Enhancement and Application Development

This forum mainly discussed the modification direction of UHPC materials. Director Lu Ya from Jiangxi Provincial Building Materials Research Institute interpreted the latest reinforcement technology standards. General Manager Yin Shi from Ningbo Shike Company proposed that polyolefin notched fibers can improve the crack resistance of UHPC, attracting industry attention.

Ganzhou Daye Shows the Technological Achievements of Metal Fibers

As a supplier of metal fiber reinforcing materials, Ganzhou Daye Company actively participated in the discussions in the sub-forum on "Material Performance Enhancement". The company's technical representative pointed out that the dispersibility and interfacial bonding performance of metal fibers are the key to improving the toughness of UHPC. The company's independently developed chopped copper-plated steel fiber products have passed national inspections, with a tensile strength of 2850MPa. They have been applied in the UHPC bridge deck pavement of a cross-sea bridge in Guangdong, effectively suppressing the development of micro-cracks.

Collaborative Innovation Drives Industry Upgrading

During the conference, Ganzhou Daye had exchanges with participating enterprises on topics such as the standardization of UHPC materials and the collaborative optimization of fibers and the matrix. The person in charge of the company said that in the future, it will deepen cooperation with design institutes and construction enterprises, focus on breaking through the research and development of corrosion-resistant fibers for marine environments and formulations with low dosage and high toughening, and help the application of UHPC in scenarios such as cross-sea projects, wind power, and nuclear power facilities.

Conclusion

This conference comprehensively demonstrated the innovation chain of UHPC technology in China, from material research and development to engineering implementation. By participating in technical discussions and industrial docking, Ganzhou Daye Metal Fiber Co., Ltd. further clarified the value of metal fibers in the high performance of UHPC. With the industry's increasing requirements for material durability and construction efficiency, reinforcing material technologies represented by metal fibers will become the key support for promoting the high-quality development of UHPC.
