Nanjing Yangtze River Cable-Stayed Bridge
Ultra-high performance concrete deck panels and precast diaphragms engineered for exceptional durability in chloride-rich marine exposure zones. Fiber-reinforced UHPC achieved 150 MPa characteristic compressive strength with self-compacting rheology for complex formwork geometries.

Project Overview
This landmark infrastructure project leveraged UHPC for critical structural elements where conventional HPC could not meet the combined demands of flexural capacity, crack-width control, and 120-year design life under aggressive environmental loading.
Technical Highlights
- Mix Design: Low water-binder ratio (W/B ≈ 0.18) with optimized silica fume and steel fiber dosage
- Durability: Chloride diffusion coefficient reduced by 85% vs. C50/60 reference concrete
- Production: Fully automated batching with real-time rheology monitoring via ICAR rheometer
