Available in PDF, EPUB and Kindle. Book excerpt: Preliminary data is encouraging. Relationships of direct tensile strength to approximated tensile strength indicate intriguing relationships. Splitting tensile approximations yield results nearly 1.5 times directly measured tensile strength, while flexural approximations yield results around 1.7 times directly measured strength to compressive strength was developed. Five water/cement ratios were tested for this study. Multiple lab trials indicate that coefficients of variation (COV) can be obtained at 6-8% for final results. The results are analyzed and a draft testing standard proposed.

Available in PDF, EPUB and Kindle. Book excerpt: Different testing methods were used in previous studies to measure the direct tensile strength of concrete. However, these methods experienced several major deficiencies such as stress concentration at the end of the specimens because of inadequate gripping and loading eccentricity and nonuniform fracture plane because of difficulties in aligning and centering the specimens during testing. This study presents the details of a new method of testing concrete under uniaxial tension. The method was developed to overcome the difficulties associated with testing methods adopted in the previous research studies. A full description of the wooden molds used in casting the specimens and the loading arrangements including the end grips, universal joints, and frame in which the specimens were tested under uniaxial tension are presented. As expected, all the tested specimens were fractured at the middle where the cross-sectional area was reduced by 20 %. Also, no crushing failure or slippage was observed at the ends of the tested specimens.

Download or read book A Standard Tensile Testing Procedure for Fiber-reinforced Concrete (FRC) and Ultra-high-performance Fiber-reinforced Concrete (UHP-FRC) Based on Double Punch Test (DPT) written by Shuveksha Tuladhar and published by . This book was released on 2017 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current test methods such as ASTM 1609, ASTM 1550 and direct tensile test are used for evaluating the mechanical properties of Fiber Reinforced Concrete (FRC) and to determine the quality of mixture in design and construction practice. These test methods show high variability in the results, requires large specimen and complicated test setup. An ideal material test method for FRC should give consistent results in determining mechanical properties such as peak strength and residual strengths. Moreover, current test methods are expensive and time-consuming as more specimens are needed to acquire reliable test results. Double Punch Test (DPT) is a simple, reliable and consistent test method for evaluating the post-cracking behavior of FRC. DPT originally developed to determine the tensile strength of plain concrete, can also be used for evaluation of peak load and post-peak behavior of FRC and Ultra-High-Performance Fiber Reinforced Concrete (UHP-FRC). This method has a simple test setup and is easier to conduct in comparison to other test methods. DPT experimental test results are seen to be more consistent than the other test methods currently in practice. The simplicity of test setup, reliability of results (low scatter due to the higher cracking surface) and smaller specimens (fewer materials used) are the major advantages of using DPT method for evaluation of post cracking response of FRC and UHP-FRC. In this research, the application of double punch test is validated for FRC and the same method has been used and developed to confirm the suitability for UHP-FRC material in determining tensile strength and behavior in post cracking phase. However, there still exist some potential issue in the DPT method that needs to be resolved. The circumferential extensometer that is used to determine the total crack opening displacement in DPT is an expensive instrument. This limits the use of DPT method in most of the industrial and research laboratories. The measurement of crack width and inspection of a number of cracks are the important parameter for evaluating the characteristics of any concrete material. It is time-consuming to measure the crack width in a test by conventional visual inspection and automated crack width measurement is indispensable. This research mainly focuses on the deriving a simple formula for estimating average and maximum crack width using the axial deformation data and optimize the time taken for each DPT test. The relation would remove the need of using the expensive circumferential extensometer for the test. Thus, DPT could be used to evaluate and compare the quality of mixture for FRC and UHP-FRC by using a simple arrangement of LVDTs.

Book excerpt: This design code for concrete structures is the result of a complete revision to the former Model Code 1978, which was produced jointly by CEB and FIP. The 1978 Model Code has had a considerable impact on the national design codes in many countries. In particular, it has been used extensively for the harmonisation of national design codes and as basic reference for Eurocode 2. The 1990 Model Code provides comprehensive guidance to the scientific and technical developments that have occurred over the past decade in the safety, analysis and design of concrete structures. It has already influenced the codification work that is being carried out both nationally and internationally and will continue so to do.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades concrete has enjoyed a renewed level of research and testing, resulting in the development of many new types of concrete. Through the use of various additives, production techniques and chemical processes, there is now a great degree of control over the properties of specific concretes for a wide range of applications. New theories, models and testing techniques have also been developed to push the envelope of concrete as a building material. There is no current textbook which brings all of these advancements together in a single volume. This book aims to bridge the gap between the traditional concrete technologies and the emerging state-of-the-art technologies which are gaining wider use.

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.

This book was released on 2008-06-11 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes a number of high-performance construction materials, including concrete, steel, fiber-reinforced cement, fiber-reinforced plastics, polymeric materials, geosynthetics, masonry materials and coatings. It discusses the scientific bases for the manufacture and use of these high-performance materials. Testing and application examples are also included, in particular the application of relatively new high-performance construction materials to design practice.Most books dealing with construction materials typically address traditional materials only rather than high-performance materials and, as a consequence, do not satisfy the increasing demands of today's society. On the other hand, books dealing with materials science are not engineering-oriented, with limited coverage of the application to engineering practice. This book is thus unique in reflecting the great advances made on high-performance construction materials in recent years.This book is appropriate for use as a textbook for courses in engineering materials, structural materials and civil engineering materials at the senior undergraduate and graduate levels. It is also suitable for use by practice engineers, including construction, materials, mechanical and civil engineers.
