This book was released on 2018 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra-high performance concrete (UHPC) is a new generation of advanced cementitious materials with superior mechanical properties that far surpass conventional concrete. However, UHPC is expensive and proprietary, and only a few field producers are available commercially in the United States. Moreover, its tensile behavior has not been well understood. This research aims to develop, characterize and model UHPC, specifically for its tensile behavior. Two viable UHPC mixes produced with locally available materials are developed, and they exhibit comparable mechanical properties to those of commercial products. An effective specimen for direct tension test (DTT) is designed and then used to evaluate both the short- and long-term tensile behavior of UHPC. The extended freeze-thaw actions have obvious impact on the tensile responses of UHPC, particularly over the post-cracking period, and the energy-based evaluation approach from DTT is more critical than the modulus-based approach to screen and evaluate material deterioration over freeze-thaw period. An analytical model is proposed to predict the tensile responses of UHPC from the bridging behavior of matrix and fibers. A fiber reinforcement efficiency function is derived to characterize the combined effects of fiber orientation, fiber snubbing and matrix spalling on the tensile behavior of UHPC. The fiber geometry and volume fraction, interfacial bond strength, and fiber reinforcement efficiency pronouncedly govern the tensile strength and hardening behavior of UHPC. The prediction capability of the analytical model is greatly improved by adjusting some coefficients that govern the hardening and softening branches of tensile stress-crack width curves. This model can effectively predict the tensile behavior of UHPC and its deterioration effect due to freeze-thaw actions. The non-contacted lap-splice pullout test is conducted to investigate the bond behavior of rebar in UHPC. The adopted analytical model can predict the bond stress-slip relation accurately. The critical embedment length and bond strength of rebar in UHPC mixes are recommended for bridge deck connection design. The comprehensive study on the tensile behavior of UHPC presented sheds light on better understanding UHPC performance in tension and provides both the experimental and analytical methods to effectively evaluate its tensile behavior.

Download or read book Ultra-High Performance Concrete UHPC written by Ekkehard Fehling and published by John Wiley & Sons. This book was released on 2015-04-20 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since. Ultra high performance concrete (UHPC) is a milestone in concrete technology and application. It permits the construction of both more slender and more durable concrete structures with a prolonged service life and thus improved sustainability. This book is a comprehensive overview of UHPC - from the principles behind its production and its mechanical properties to design and detailing aspects. The focus is on the material behaviour of steel fibre-reinforced UHPC. Numerical modelling and detailing of the connections with reinforced concrete elements are featured as well. Numerous examples worldwide - bridges, columns, facades and roofs - are the basis for additional explanations about the benefits of UHPC and how it helps to realise several architectural requirements. The authors are extensively involved in the testing, design, construction and monitoring of UHPC structures. What they provide here is therefore a unique synopsis of the state of the art with a view to practical applications.

Available in PDF, EPUB and Kindle. Book excerpt: Ultra-high performance concrete (UHPC) is an advanced cement-based composite material with compressive strength of over 120 MPa, high toughness, and superior durability. Since its development in the early 1990s, UHPC has attracted great interest worldwide due to its advantages. This book covers material selection and mixture design methods for developing UHPC, as well as the performance of UHPC, including fresh and hardened properties, setting and hardening, dimensional stability, static and dynamic properties, durability, long-term properties, and self-healing properties. A range of potential applications and case studies are presented to illustrate how UHPC meets requirements for lightweight, high-rise, large-span, heavy-load bearing, fast-construction, and highly durable structures in civil and construction engineering. Also introduced is a typical new concrete, seawater sea-sand UHPC, which avoids the use of freshwater and river sand in marine construction. The first book to fully cover the design, performance, and applications of UHPC, this is ideal for concrete technologists, designers, contractors, and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: This is the proceedings of the 4th International Conference on Strain-Hardening Cement-Based Composites (SHCC4), that was held at the Technische Universität Dresden, Germany from 18 to 20 September 2017. The conference focused on advanced fiber-reinforced concrete materials such as strain-hardening cement-based composites (SHCC), textile-reinforced concrete (TRC) and high-performance fiber-reinforced cement-based composites (HPFRCC). All these new materials exhibit pseudo-ductile behavior resulting from the formation of multiple, fine cracks when subject to tensile loading. The use of such types of fiber-reinforced concrete could revolutionize the planning, development, dimensioning, structural and architectural design, construction of new and strengthening and repair of existing buildings and structures in many areas of application. The SHCC4 Conference was the follow-up of three previous successful international events in Stellenbosch, South Africa in 2009, Rio de Janeiro, Brazil in 2011, and Dordrecht, The Netherlands in 2014.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra-High Performance Concrete (UHPC) is an advanced concrete material with superior mechanical strength, high tensile ductility, and exceptional durability, including negligible permeability. Despite these excellent material properties, the use of UHPC in structural applications is limited because of the high cost of commercially available UHPC products. Therefore, developing non-proprietary UHPC mixtures using local materials is a viable way to reduce the initial cost of UHPC. In this research, sustainable and cost-effective UHPC mixtures were developed using locally sourced materials so that UHPC may be more affordable to a wider variety of applications. Specifically, locally available Type I-II cement, local sand with a top size of 4.75 mm (0.187 inch), high range water reducing admixture, domestic steel fibers, and Class F fly ash were used in this research. These material selections improved the sustainability of UHPC. Two final mixtures (plain and fiber reinforced) were recommended as the UHPC mixtures. The greatest compressive strengths obtained in this research were 138.1 MPa (20,030 psi) for plain UHPC and 165.8 MPa (24,030 psi) for fiber reinforced mixture. The greatest flexural strengths were 12.95 MPa (1,230 psi) and 14.35 MPa (2,080 psi) for plain and fiber reinforced UHPC, respectively. After developing the UHPC mixtures, physical properties: drying shrinkage and permeable porosities of plain and fiber reinforced mixtures were investigated. The drying shrinkage of plain UHPC was greater than that of fiber reinforced UHPC by 27%. The lowest permeable porosities obtained were 2.4% and 2.6% for plain and fiber reinforced mixtures, respectively. In addition to mechanical and physical properties, the durability of UHPC mixtures was also studied. Rapid chloride permeability testing was performed on plain UHPC which showed very low chloride ion penetrability. Resistance of plain and fiber reinforced UHPC mixtures to freeze-thaw cycles was studied and observed no damage due to frost action with a durability factor of 100. Additionally, sulfate resistance of the final two mixtures was evaluated by submerging the specimens under 5% sodium sulfate for one year. The maximum expansions in plain and fiber reinforced specimens were 0.07% and 0.06%, respectively, which indicated excellent resistance to sulfate attack.

Available in PDF, EPUB and Kindle. Book excerpt: "In the research project presented in this PhD-thesis, an innovative type of fibre concrete is developed, with improved both the tensile strength and the ductility: the Hybrid-Fibre Concrete (HFC). The expression "Hybrid" refers to the "hybridisation" of fibres: short and long steel fibres were combined together in one concrete mixture. This is opposite to conventional steel fibre concretes, which contain only one type of fibre. The basic goal of combining short and long fibres is from one side to improve the tensile strength by the action of short fibres, and from the other side to improve the ductility by the action of long fibres." "In this research project, all important aspects needed for the development and application of Hybrid-Fibre Concrete have been considered. In total 15 mixtures, with different types and amounts of steel fibres were developed and tested in the fresh state (workability) as well as in the hardened state (uniaxial tensile tests, flexural tests, pullout tests of single fibres and compressive tests). A new analytical model for bridging of cracks by fibres was developed and successfully implemented for tensile softening response of HFC. At the end, the utilisation of HFC in the engineering practice was discussed, including a case-study on light prestressed long-span beams made of HFC."--BOOK JACKET.
