The first property listed, the ultimate tensile strength of 4.6 MPa, is slightly larger than the accepted tensile strength of standard fiber-reinforced concretes, (4.3 MPa). More notable, however, is the extremely high ultimate strain value of 5.6% when compared to most FRC's ultimate strain values ranging in the few hundredths of a percent. To evaluate the vulnerability of ultra-high performance fibre-reinforced concrete (UHPFRC) infrastructure to rigid projectile penetration, over the last few years CEA-Gramat has led an experimental and numerical research programme in collaboration with French universities. Dear Colleagues, In the mid-1990s, reactive powder concrete, which is a precursor of ultra-high-performance fiber-reinforced concrete (UHFFRC), currently available in several countries, was first introduced by French engineers in order to overcome several drawbacks of ordinary concrete, including a low strength-to-weight ratio, high brittleness, and low durability.

This paper addresses the mix design and properties assessment of an UHPFRC. The design of the concrete composites is based on the modified Andreasen & Andersen particle packing model. Limestone and In the past decade significant advances have been made in the field of high performance concretes (HPC). The next generation of concrete, ultra-high performance concrete (UHPC), exhibits exceptional tensile and compressive strength characteristics that make it well suited for use in highway bridge structures. of ultra-high performance concrete such as, Compressive strength, modulus of elasticity, Poisson’s ratio, flexural strength under the name. and (RPC) with 2.5% of short slender steel fibers (lf = 13 mm), tensile strength.

Fibre-reinforced Concrete for Industrial Construction 2017-11

UHPC is characterized by being a steel fibre-reinforced cement composite material with compressive strengths in excess of 150 MPa, up to and possibly exceeding 250 MPa. Superior performance was observed in terms of stiffness, yield & maximum strength, when three side UHPFRC jacket was used.
