Download or read book Fresh Concrete written by P. Bartos and published by Elsevier. This book was released on 2013-10-22 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fresh concrete is generally featured in publications on concrete technology where the focus is often on fundamental rheology or diverse research methods, or the standards describe the tests but do not provide practical advice on interpretation of the results. This book aims to fill the gap between highly scientific and fundamental works and the many fragmented test specifications. It summarises the existing knowledge on the properties of fresh concrete in a form accessible to practicing engineers and concrete technologists. It includes a manual of practical tests which cover both the standard tests in major countries and new tests specifically applicable to site testing. The testing equipment required and the procedures are described in sufficient detail for the tests to be carried out, with references to selected national standards when compliance with specific conditions applicable in those countries is required. Particular attention is paid to properties of special fresh concrete mixes which are increasingly used in practical construction. The work will be of interest to engineers and others involved in the research, development, design and execution of concrete construction, including those working in EEC countries.
Book Synopsis Development of a Portable Rheometer for Fresh Portland Cement Concrete by : Eric Patrick Koehler
Download or read book Development of a Portable Rheometer for Fresh Portland Cement Concrete written by Eric Patrick Koehler and published by . This book was released on 2004 with total page 836 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to identify an effective field test method for measuring the workability of concrete in general and of high-microfines concrete in particular. The workability of fresh concrete has traditionally been measured with the slump test, which provides an inadequate indication of workability. For certain concrete mixtures--such as those containing fiber reinforcement, ground granulated blast furnace slag, or high contents of aggregate microfines--the slump test can provide inaccurate and misleading results. The need for a better test method for workability is well established within the concrete industry. Based on a literature search in which 61 existing workability test methods were identified and on feedback from government, industry, and academia, criteria for an improved workability test device were developed. It was determined that the best approach to measuring workability would be to develop a new portable rheometer. The ICAR rheometer--a low-cost, fully portable test device for concrete--was developed and tested. A first generation prototype was built using off-the-shelf components. The ICAR rheometer is approximately the size of a drill and can be operated by hand or positioned above a standard container. It is capable of measuring a flow curve or performing a stress growth test and is appropriate for nearly the full range of concrete workability ranging from a slump of approximately 2 inches to self-consolidating concrete. Experimental testing on a wide range of concrete mixtures indicated that the ICAR rheometer was able to detect changes in workability and rheology successfully. As a dynamic test that adds energy to concrete, it is well suited for measuring high-microfines concrete and other highly thixotropic concrete mixtures. Field testing confirmed the portability of the ICAR rheometer. The low cost and portable form factor of the ICAR rheometer can make the routine measurement of concrete rheology in the field an economically viable solution to characterizing concrete workability
Book Synopsis Production Methods and Workability of Concrete by : P.J.M. Bartos
Download or read book Production Methods and Workability of Concrete written by P.J.M. Bartos and published by CRC Press. This book was released on 2004-06-02 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical production of ordinary and special, high performance concretes and their behaviour and properties when fresh are the main themes of this book. It derives from the International RILEM Conference held in Paisley, Scotland in June 1996, and represents the culmination of the work of two RILEM Technical Committees (145 WSM Workability of Special Mixes, and 150 ECM Efficiency of Concrete Mixers). Very significant advances have been made recently in the development of concrete with outstanding properties. Such advances in research must be matched by progress in the technology of concrete production. This book focuses on production methods and on workability and handling, two fundamental and closely linked stages of the concrete construction process. It has a strongly practical emphasis, with many contributions showing how to build effectively using the many high performance concretes which have progressed from research into construction in recent years. The main themes covered are: production mixers and mixing processes; production methods; sprayed and very dry precasting mixes; fibre reinforced concrete; flowing and superfluid mixes; rheology; test methods; mix design and models; special cements and concretes.

Download or read book Concrete Mix Design, Quality Control and Specification, Fourth Edition written by Ken W. Day and published by CRC Press. This book was released on 2013-11-11 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nature of concrete is rapidly changing, and with it, there are rising concerns. Thoroughly revised and updated, this fourth edition of Concrete Mix Design, Quality Control and Specification addresses current industry practices that provide inadequate durability and fail to eliminate problems with underperforming new concrete and defective testing. Many specifications now require additional criteria in an attempt to improve durability or other properties. This book discusses the trend towards adding performance requirements to existing prescriptive specifications. It also explores the matter of prescription versus performance specification and especially the specification of non-strength-related performance such as durability. What’s new in the Fourth Edition: Examines water-to-cement ratio as a declining criterion of quality and durability Discusses the diminishing availability of suitable natural sands and growing industry concerns regarding the environmental impact of their use Considers advances in concrete admixtures and their ever-increasing use Advocates reliability of testing as a vital feature of the shift from prescriptive to performance specifications Addresses cement replacement materials as they relate to greenhouse gas and sustainability Concrete Mix Design, Quality Control and Specification explores producing, designing, controlling, or specifying concrete, and addresses issues related with sustainability and the impact of new concrete materials such as ready mixed geopolymers, magnesium oxide, and calcium carbonate. The text is an ideal resource for concrete technologists, producers and specifiers, and contractors on large projects

Book Synopsis Rheology of Fresh Cement-Based Materials by : Qiang Yuan
Download or read book Rheology of Fresh Cement-Based Materials written by Qiang Yuan and published by CRC Press. This book was released on 2022-12-28 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces fundamentals, measurements, and applications of rheology of fresh cement-based materials. The rheology of a fresh cement-based material is one of its most important aspects, characterizing its flow and deformation, and governing the mixing, placement, and casting quality of a concrete. This is the first book to bring the field together on an increasingly important topic, as new types of cement-based materials and new concrete technologies are developed. It describes measurement equipment, procedures, and data interpretation of the rheology of cement paste and concrete, as well as applications such as self-compacting concrete, pumping, and 3D printing. A range of other cement-based materials such as fiber-reinforced concrete, cemented paste backfills, and alkali-activated cement are also examined. Rheology of Fresh Cement-Based Materials serves as a reference book for researchers and engineers, and a textbook for advanced undergraduate and graduate students.

This book was released on 2023-10-13 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the work of the RILEM TC 266-MRP, whose purpose was to enhance the reliability of rheological measurements performed on cement-based materials. It makes users more aware of potential sources of errors in the measurements, and provide guidelines on how to observe, counteract or eliminate the errors. Improving the reliability of rheological measurements will further enhance the use of rheology to investigate different aspects of the fresh properties of cement-based materials. After an introduction into mix design and applications, the book delivers a comprehensive overview of rheology definitions, behavior, and parameters; rheometers; measuring and analysis procedures; difficulties and challenges during measurements; relationships with specific empirical tests; and the behavior of concrete near a surface. This report on the measurement of rheological properties of complex materials such as concrete enables readers to understand the applicable concepts of rheology, and address the challenges on the measuring procedures, the rheological models and some errors and limitations of rheometers used.
