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.

Keywords Ultra High Performance Fibre Reinforced Concrete Reinforced concrete beams Strengthening Layers Jackets Ultra-high-performance concrete (UHPC) exceeds the performance of normal or high-strength concrete, allowing for the construction of more slender and efficient reinforced concrete (RC) structures. This is achieved using ultra-fine constituents and reactive powders which improve the mechanical properties and durability, yet increases the brittleness [ 1 , 2 ]. Ultra high performance fiber reinforced concrete (UHPFRC) is a concrete type with superior mechanical properties and of a relatively high tensile strength.

High-performance fiber-reinforced cementitious composites (HPFRCCs) are a group of fiber-reinforced cement-based composites which possess the unique

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. Although such concretes require large amounts of cement This research work analyses the influence of the use of by-products from a fluorite mine to replace the fine fraction of natural aggregates, on the properties of Ultra-High-Performance Fibre-Reinforced Concrete (UHPFRC). Replacing natural aggregates for different kinds of wastes is becoming common in concrete manufacturing and there are a number of studies into the use of waste from the Ultra-high-performance concrete. Ultra-high-performance concrete is a new type of concrete that is being developed by agencies concerned with infrastructure protection. 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.

Ultra‐high performance concrete with a compressive strength of more than 140 N/mm2 reacts very brittle without the addition of fibres. At designing economical and resource‐efficient building components as well as performance‐optimized materials, the supporting effects of the additional microfibres must be considered.
