PDF Ultra High Performance Concrete Highway Bridge

Developed in France during the 1990s, ultra high performance concrete (UHPC) has seen limited use in North America. UHPC consists of sand, cement, and silica fume in a dense, low water-cement ratio (0.15) mix. Compressive strengths of 18,000 psi to 30,000 psi and low permeability can be achieved, depending on the curing process.
