KING Construction Products Group Launches Ultra High-Performance, Fiber-Reinforced Concrete (UHPFRC) UP-FX Poly is the result of an excellent research and development program conducted by Montreal Polytechnique, a proud partner of King Packaged Materials Company.

Fine silica sand and short steel fibres are also included in the material. Keywords: compressive strength, fiber-reinforced concrete, macrocrack, microcrack, tensile strength. Date: 12/1/2001. Abstract: Ultra-high-performance fiber-reinforced concretes (UHPFRC) are the outcome of a quest that began in the 1930s to find means of increasing the mechanical strength of concrete, in particular its compressive strength.

Abstract. An original concept is presented for the durable rehabilitation and strengthening of concrete structures. The main idea is to use ultra-high performance fibre reinforced concrete (UHPFRC) complemented with steel reinforcing bars to protect and strengthen those zones of the structure that are exposed to severe environmental influences and high mechanical loading. 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.

The main goal is to find an.

Dog-bone shaped specimens have been tested under direct tensile loading, and standard cubes have been tested in compression. 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.
