Inverse Analysis of UHPFRC Beams with a Notch to Evaluate Tensile Behavior [PDF]
Advances in Materials Science and Engineering, 2017 Recently, ultra high performance fiber reinforced concrete (UHPFRC) has been developed to attain considerably increased compressive cracking strength and ductile tensile behavior with high tensile strength through adding straight steel fibers in concrete

Experimental investigation of a keying joint cast in UHPFRC between precast UHPFRC bridge elements [PDF]
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 ...

Flexural behaviour and evaluation of ultra-high-performance fibre reinforced concrete beams cured at room temperature [PDF]
Scientific Reports, 2021 Heat treatment is often required for ultra-high-performance concrete (UHPC) to achieve high strength. To broad its use in construction, the effect of different curing conditions on the properties of UHPC has been developed for many years.

Structural elements made with highly flowable UHPFRC: Correlating computational fluid dynamics (CFD) predictions and non-destructive survey of fiber dispersion with failure modes [PDF]
, 2017 Structural design with highly flowable Fibre Reinforced Concrete has to duly take into account the preferential alignment of fibers, which can be governed through the rheological properties of the fluid mixture and the casting process and by the geometry

UHPFRC tensile creep at early age [PDF]
Materials and Structures, 2008 Ultra high performance fibre reinforced concrete (UHPFRC) early age viscoelastic behaviour under tension was investigated. The tests results showed a high creep potential due to the high volume paste (88%). This result is of major importance because the viscoelastic properties contribute to mitigating the high early age stresses generated under ...

Journal of Civil Engineering and Architecture, 2020 The aim of the Student Workshop “Material Optimization and Geometric Exploration” (ENSA Paris-Belleville and University of Naples Federico II) is to discover the possibilities offered by new materials, starting from their characteristics. The final goal is to build a synthetic pavilion, which—in the last session—demonstrates ultra-high performances ...
