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). Also, adding steel fibers increases durability by Concrete Mix Proportions for Trial Mix 2. Weight of Coarse aggregate = 1073.33 kg/m 3. 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. Ductal ® Ultra High Performance Concrete. (2014). Weight of Cement = 384.8 kg/m 3. 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. A response surface design of experiments was developed for identifying the optimum values of coarse-to-fine aggregate weight ratio, superplasticizer content and steel fiber volume fraction in an ultra-high-performance concrete mix with a specific cementitious binder composition, binder content and water-to-binder ratio. Saturated colors are achieved with UV stable pigments that are integral to the mix and protected by the extremely dense ultra high performance concrete matrix. Weight of Water = 197.4 kg/m 3. ABSTRACT. Ultra High Performance Concrete (UHPC) or Ultra-high fibre-reinforced concrete (UHPFRC) require high dosages of cement and admixtures. NON-PROPRIETARY ULTRA-HIGH PERFORMANCE CONCRETE MIX DESIGN FOR ABC APPLICATIONS Quarterly Progress Report For the period ending February 29, 2020 Submitted by: Behrouz Shafei, Ph.D., P.E. This emerging technology report gives an overview of ultra-high-performance concrete. 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. 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). In Europe, concrete strength is usually measured in megapascals, which is abbreviated MPa. 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 Steelike, Inc. offers several variations of UHPC aka UHPFRC mix designs, marketed under the trademark Steelike®.All variations of Steelike® Mix Designs meet or exceed properties stipulated in State DOT specifications as well as in published FHWA documents. Design of Ultra-High Performance Concrete Jetty in Marine Environment August 2014 Conference: Proceedings of the 12th International Conference on Concrete Engineering & … It is a class of concrete that is exceptionally strong, durable, and cost effective. Due to their exceptional durability and strength (Compressive strengths: 130 to 250 MPa , and flexural strengths: 20 to 50 MPa), CHRYSO has developed a range of highly technical solutions to meet the most stringent requirements of UHPFRC which allow for: The high costs currently associated with UHPC might limit its widespread use. Weight of Fine aggregate =790.3 kg/m 3. High-performance concrete (HPC) is concrete that has been designed to be more durable and, if necessary, stronger than conventional concrete. Most high-performance concretes have a high cementitious content and a water-cementitious material ratio of 0.40 or less. The development of Ultra-High Performance Concrete (UHPC) opened new research directions for enhancing the architectural design, sustainability and serviceability of concrete structures.
