Further introductory information on UHPC can be found in Ultra-High Performance Concrete: A State-of-the-Art Report for the Bridge Community (FHWA-HRT-13-060). This emerging technology report gives an overview of ultra-high-performance concrete. University of Nebraska, 2019 Advisor: Jiong Hu Ultra-high performance concrete (UHPC) is a new class of concrete that has superior workability, as well as mechanical and durability properties that far exceed those Since rheological parameters and compressive strength are fundamental properties of concrete in two different stages of production, the correlation between rheological parameters and compressive strength has been used instead of using water-cement ratio versus compressive strength relationship. High-performance concrete (HPC) is concrete that has been designed to be more durable and, if necessary, stronger than conventional concrete. (2014). There is a growing interest in expanding the use of Ultra-high performance concrete (UHPC) from bridge deck joints for accelerated bridge construction to complex architectural and advanced structural applications. Chapter 2.2 Mix design of Ultra-High Performance Concrete. CONCRETE High-early-strength concrete, also called fast-track concrete, achieves its specified strength at an earlier age than normal concrete. This paper addresses the mix design and properties assessment of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC). Ultra-high performance fibre reinforced concrete mix design in central Canada.

Remy}, year={2008} } A mix design procedure for high-performance concrete mixes has been presented in this paper. In all honesty I think he explained the entire mix to me, but I retained only the word Silica. Weight of Fine aggregate =790.3 kg/m 3. Ultra High Performance Concrete (UHPC) or Ultra-high fibre-reinforced concrete (UHPFRC) require high dosages of cement and admixtures. Katrin Habel, a Jean-Philippe Charron, b Shadi Braike, b R. Douglas Hooton, a Paul Gauvreau, a Bruno Massicotte b. a Department of Civil Engineering, University of Toronto, 35 St. George Street, Toronto, ON M5S 1A4, Canada. is an admixture designed to produce extremely dense and strong concrete. 5,000 psi concrete that actually tests at 5,600 psi is not defective. Weight of Coarse aggregate = 1073.33 kg/m 3. The increasing demands of sustainable design and construction with economical sections, reduced cover, and more efficient time schedule require more flexibility in the design methodologies. The high costs currently associated with UHPC might limit its widespread use. Ductal ® Ultra High Performance Concrete. He said that the mix would be a fine one, with a high quantity of Silica. First Ultra-High-Performance Fibre-Reinforced Concrete Footbridge in Spain: Design and Construction. The design of the concrete mixtures is based on the aim to achieve a densely compacted cementitious matrix, employing the modified Andreasen & … Design and field testing of tapered H-shaped Ultra High Performance Concrete piles by Thomas L. Vande Voort A thesis submitted to the graduate faculty in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Major: Civil Engineering (Structural Engineering) Program of Study Committee: Sri Sritharan, Co-major Professor The Ultra High Performance Concrete (UHPC) consists of sand, cement, crushed quartz, silica fume, superplasticizer, water and steel fibers, with water-to cement (w/c) ratio of 0.24 or lower. In addition, the absence of mechanical consolidation due to the high fluid nature of the UHPC materials can reduce construction time for new overlay and/or rehabilitation of … Structural Engineering International: Vol. Most high-performance concretes have a high cementitious content and a water-cementitious material ratio of 0.40 or less. It is a class of concrete that is exceptionally strong, durable, and cost effective. 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.. Cor-Tuf UHPC is the premier material for Low Impact Design (LID). I now know that what he was describing is the mix we today refer to as UHPC or Ultra High Performance Concrete. using ultra-high performance concrete (UHPC) can provide significant improvement in durability and service life of the overlay pavement. ABSTRACT. 24, No. Super-SIX Ultra High Performance Mix Recipe Super-SIX-Admix™ is a multi-component proprietary blend of SIX unique admixtures. The development of Ultra-High Performance Concrete (UHPC) opened new research directions for enhancing the architectural design, sustainability and serviceability of concrete structures. Ultra High Performance Concrete The material provides compressive strengths up to 29,000 psi and flexural strengths up to 7,000 psi. In Europe, concrete strength is usually measured in megapascals, which is abbreviated MPa. Ductal® Ultra-High Performance Concrete (UHPC) Ductal is a high-tech construction material with the superior qualities of resistance to compression, ductility, longevity, eco-efficiency, insulation and aesthetics. Cor-Tuf is the exclusive licensed producer of Cor-Tuf Ultra High Performance Concrete (UHPC) in the United States and the world. Design Options Comparison: TAKTL with Other Glass Fiber Reinforced Concrete TAKTL’s surface quality and range of pattern, texture and finish options are unmatched. This premium blend makes it easy to produce Ultra high performance concrete (UHPC), also known as Engineered Concrete Composition (ECC) and Reactive Powder Concrete (RPC). How is High Performance Concrete obtained in practice? By careful selection of raw materials (including chemical/mineral admixtures) & appropriate mix design to achieve the desired performance objectives. Weight of Water = 197.4 kg/m 3. When normal ready-mix concrete is made the largest aggregates in the mix can range from 1-1/2 inches down to 3/8ths of an inch in size with compressive strengths that can be as high as 10,000 psi. By omitting coarse aggregates in the mix, density and mechanical homogeneity can be maximized.
