Permeability of ultra high performance fiber reinforced concretes (UHPFRC) under high stresses

Materials and Structures, 2006
Ultra High Performance Fiber Reinforced Concretes (UHPFRC) present outstanding mechanical properties and a very low permeability which make them very attractive for the rehabilitation of existing structures and for new conceptions. UHPFRC are characterized by a significant tensile strain hardening (multiple cracking stage) that can be used to optimize ...

Compressive Behavior of Ultra-High-Performance Fiber-Reinforced Concrete

ACI Materials Journal, 2007
An experimental program aimed at determining ultra-high performance fiber-reinforced concrete (UHPFRC) uniaxial compressive behaviors was conducted. Overall stress-strain behavior, strain capacity, modulus of elasticity, and strength of both steam-treated and untreated UHPFRC were determined by analyzing results of compression tested cylinders ...

Dynamic mechanical behaviour of ultra-high performance fiber reinforced concretes

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2008
Ultra-high performance fiber reinforced concretes (UHPFRC) were prepared by replacing 60% of cement with ultra-fine industrial waste powder. The dynamic mechanical behaviour of UHPFRC with different fiber volume fraction was researched on repeated compressive impact in four kinds of impact modes through split Hopkinson pressure bar (SHPB).

Shear behavior of fiber-reinforced ultra-high performance concrete beams

Engineering Structures, 2018
Abstract Twenty I-shaped beams made of ultra-high performance concrete (UHPC) with different steel fiber content (up to 2% by volume) and with varying degrees of shear reinforcement (no stirrups or with diameter 10 mm stirrup, 125–300 mm spacing) were tested in shear. The mean compressive strength of the concrete was around 170 MPa.

French Standards for Ultra-High Performance Fiber-Reinforced Concrete (UHPFRC)

2017
The French standard NF P18-470 related to UHPFRC specification, performance, production and conformity, published in July 2016, is a self-supporting document with distinct scope, however with the same outline as NF EN 206/CN, the French standard for ordinary structural concrete consistent to the European standard.
