Ultra High Performance Concrete(UHPC) What is UHPC It is also known as Reactive Powder Concrete (RPC) It is a high strength, ductile material formulated by combining portland cement, silica fume, quartz flour, fine silica sand, high-range water reducer, water, and steel or organic fibers. This class of concrete has been demonstrated to facilitate solutions that address specific problems in the United States highway bridge infrastructure. This innovative material produces concrete elements that are up to 10 times stronger than conventional concrete.

Ductal ® Ultra High Performance Concrete. What is Ultra-High Performance Concrete? concrete with very high durability and very low permeability is consid-ered to have high-performance properties. The term Ultra-High Performance Concrete (UHPC) refers to a relatively new class of advanced cementitious composite materials whose mechanical and durability properties far surpass those of conventional concrete. An Ultra-High Strength Concrete with a compressive strength above 120 MPa. Design – Using Ultra High Performance Concrete Dean Bierwagen April 12th, 2006 Why UHPC? 8 Ultra High Performance Concrete The UHPC is being considered for use in a wide variety of highway infrastructure applications. Ultra-high performance concrete has a discontinuous pore structure that reduces liquid ingress, significantly enhancing durability compared to conventional and high-performance concretes. With the fast development in high-performance concrete (HPC), the usage of fibres gained special attention. Fine Concrete, LLC is one of a select group of firms in the United States holding a sub-license to design and fabricate with Ductal ®, an ULTRA HIGH PERFORMANCE CONCRETE.. 17-1. An Ultra-High-Performance Concrete with an optimised particle packing by using a special selection of fine and ultrafine particles, low porosity and high durability. CRC is an abbriviation for Compact Reinforced Composite and its original form was developed and patented by Hans Henrik Bache at Aalborg Portland. Ultra High Performance Concrete - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. These are deflection softening, deflection hardening, tensile hardening and high-energy absorption (Naaman and Reinhardt, 2003). • FHWA –UHPC is a cementitious composite material composed of an optimized gradation of granular constituents, a water‐to‐cementitious materials ratio less than 0.25, and a high percentage of discontinuous internal fiber reinforcement. 1. Naaman and Reinhardt (2003) have very well defined research in this area and categorized cementitious composites into four categories. What is Ultra-High Performance Concrete? Hi-Con works with a special type of Ultra High Performance Concrete (UHPC), we call it CRC i2®. The use of a minimum content of fibres to guarantee a minimum degree of matrix ductility. Bickley and Fung (2001) demonstrated that 40 MPa (6,000 psi) high-performance concrete for bridges could be eco-Fig. • ACI 239 – Ultra-High Performance Concrete – Concrete, ultra-high performance - concrete that has a minimum specified compressive strength of 150 MPa (22,000 psi) with specified durability, tensile ductility and toughness requirements; fibers are generally included to achieve specified requirements.
