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. 2011-02-01 · Since CFRP tendons and concrete are brittle materials, ultra high performance fibre reinforced concrete (UHPFRC) is used in this study because of its main characteristics, i.e. high strength in compression and tension, excellent durability, and ductility which prevents brittle fracture of the elements.

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. Modelling the behaviour of ultra high performance fibre reinforced concrete Kenneth Awinda *1, Jiye Chen 1, Stephanie Barnett 1, Dominic Fox 1 1School of Civil Engineering and Surveying, University of Portsmouth *Corresponding author, email Kenneth.awinda@port.ac.uk Abstract The Cohesive Crack Model (CCM) is the most commonly accepted discrete Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) is a potential candidate for protective constructions. 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.

What's more, the Abstract. This study investigates the behavior of ultra-high-performance fiber- reinforced concrete (UHPFRC) with hybrid macro-micro steel and macro The optimised material composition results in high compressive strength and Structural implications of ultra-high performance fibre-reinforced concrete in High-performance fiber-reinforced cementitious composites (HPFRCCs) are a group of fiber-reinforced cement-based composites which possess the unique Ultra-high-performance fiber-reinforced concrete. (UHPFRC) is a breakthrough in modern concrete mix design with compressive strengths benchmarking 150. 6 Sep 2017 The term UHPC stands for Ultra-High-Performance Fibre-Reinforced Concrete. It did not appear from nowhere, but from decades of evolution The aim of this work is to describe the resistance of ultra high performance fibre reinforced concrete (UHPFRC) to projectile impact. The main goal is to find an.
Ultra-high performance fibre reinforced concrete (UHPFRC) may be an alternative for some structure types, especially in very aggressive environments, because it draws from the latest concrete industry developments to deliver high strength and durability.
