In the process of developing large bridges towards higher spans and longer lifespans, one of the core challenges is how to significantly reduce self-weight without sacrificing structural strength. Addressing this cutting-edge engineering challenge, Co-nele Machinery provided a customized UHPC preparation solution for a key research project of China Railway Bridge Science Research Institute Co., Ltd.[Qingdao, Shandong Province, China] – Co-nele Machinery, a leading domestic manufacturer of UHPC mixing equipment, announced today that its innovative UHPC (Ultra-High Performance Concrete) mixing solution has been successfully applied and is operating stably in an advanced bridge research project of China Railway Bridge Science Research Institute Co., Ltd. The core of this project involves two highly integrated mobile modular UHPC mixing plants. Their exceptional flexibility and reliability, and their core equipment – the CMP1500 planetary mixer – with its superior mixing uniformity and stability, ensured the precise production of C120 lightweight ultra-high-performance concrete (UHPC), directly producing the key material for bridge weight reduction – C120 lightweight UHPC – on-site.This provides crucial material support for the revolutionary "weight reduction" of bridge structures.
UHPC mobile modular mixing plants
What specialized equipment is needed to produce ultra-high-performance concrete (UHPC)?
Designed for challenging materials: C120 lightweight UHPC requires the uniform mixing of ultra-fine powders, microfibers, and lightweight aggregates, which is a great challenge for mixing equipment. The CO-NELE CMP1500 planetary mixer, with its unique planetary motion trajectory, achieves high-intensity shear and convection of materials in three-dimensional space, ensuring the homogeneity of the material's microstructure, which is key to achieving the expected ultra-high performance.What new technologies are used for bridge weight reduction?
The concrete produced by this solution reaches the C120 strength level while significantly reducing density. This directly means a substantial reduction in the self-weight of the bridge superstructure, which can optimize the design of the substructure, reduce foundation costs, improve seismic performance, and extend the overall lifespan.UHPC Mobile Modular Mixing Plant
Responding to the flexibility of research and construction: The deployment of two UHPC mobile modular mixing plants demonstrates high site adaptability and rapid response capabilities, perfectly matching the needs of the entire process from laboratory research and development to on-site verification and large-scale construction. This project faced the stringent challenge of achieving extreme uniformity and stability in the performance of concrete materials. The core of the solution provided by Co-nele is the CMP1500 planetary concrete mixer, integrated into each batching plant. This model, with its unique planetary mixing trajectory, achieves three-dimensional, high-intensity shearing and mixing of ultra-fine powders, fibers, and lightweight aggregates, ensuring the microstructural uniformity of C120 grade lightweight UHPC, thus guaranteeing its ultra-high mechanical properties and durability. The successful application of this lightweight, high-strength material provides crucial material science support for reducing the self-weight of bridge superstructures, optimizing substructure design, and improving overall seismic resistance and long-term service performance.
