Experimental investigation of a keying joint cast in UHPFRC between precast UHPFRC bridge elements
Materials and Structures, 2022 AbstractUltra High-Performance Fiber-Reinforced Cementitious Composite (UHPFRC) is increasingly popular for new structural designs thanks to its high resistance both in tension and compression. When UHPFRC is complemented with steel reinforcing bars or prestressing tendons, the structure remains waterproof and crack-free under service conditions ...

Punching shear resistance of UHPFRC [PDF]
IABSE Reports, 2019 <p>Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) is a high performance cementitious material with enhanced strength in tension and compression and significantly high energy absorption in the post crack region. Its mix composition is not much dissimilar from that of normal strength concrete.
