Book excerpt: "Methods for determining the workability of freshly mixed Portland-cement concrete with slumps less than 51 mm (2 in) were investigated. Four potential methods to determine the workability of concrete were proposed for evaluation and development. The methods included two moving-object methods, one free-orifice method, and a vibrating-slope method. The report outlines modifications to these existing techniques and equipment to permit the measurement of rheological properties at two or more shear rates. The vibrating-slope apparatus (VSA) was selected for further development. (Questions about this report should be addressed to Dr. Paul F.

Available in PDF, EPUB and Kindle. Book excerpt: Estimating, modelling, controlling and monitoring the flow of concrete is a vital part of the construction process, as the properties of concrete before it has set can have a significant impact on performance. This book provides a detailed overview of the rheological behaviour of concrete, including measurement techniques, the impact of mix design, and casting. Part one begins with two introductory chapters dealing with the rheology and rheometry of complex fluids, followed by chapters that examine specific measurement and testing techniques for concrete. The focus of part two is the impact of mix design on the rheological behaviour of concrete, looking at additives including superplasticizers and viscosity agents. Finally, chapters in part three cover topics related to casting, such as thixotropy and formwork pressure. With its distinguished editor and expert team of contributors, Understanding the rheology of concrete is an essential reference for researchers, materials specifiers, architects and designers in any section of the construction industry that makes use of concrete, and will also benefit graduate and undergraduate students of civil engineering, materials and construction. Provides a detailed overview of the rheological behaviour of concrete, including measurement techniques, casting and the impact of mix design The estimating, modelling, controlling and monitoring of concrete flow is comprehensively discussed Chapters examine specific measurement and testing techniques for concrete, the impact of mix design on the rheological behaviour of concrete, particle packaging and viscosity-enhancing admixtures

Book excerpt: This book is trying to help expand the knowledge of fresh concrete workability. Concrete workability depends on lots of parameters and varies significantly with conditional alteration. The temperature is of great importance determining the workability. This book presents theoretical information and experimental discussions investigating the influence of fresh concrete temperature and ingredients on the workability. Programming and different statistical programs are applied to include the most appropriate results. Artificial neural network prediction of workability is investigated in two situations; with and without concrete temperature. The most relevant cutting edge studies on this issue are cited and discussed to support the readers for the future studies. Ce livre essaie de faire progresser la connaissance de la fluidité du béton frais. La fluidité du béton dépend de beaucoup de paramètres et varie de manière significative avec le changement des conditions (température, humidité, souffle du vent, lumière du soleil). La température a beaucoup d'importances pour déterminer la fluidité. Ce livre présente des informations théoriques et des discussions expérimentales pour examiner l'influence de la température du béton frais et les ingrédients sur la fluidité. La programmation et les différents programmes statistiques ont été appliqués afin d'obtenir les résultats les plus appropriés. La prédiction de fluidité de RNA (le réseau de neurones artificiels) a été étudié dans deux situations: avec et sans température du béton frais. Les plus pertinentes recherches, concernant ce sujet, ont été faites pour appuyer les lecteurs aux études futures.

Available in PDF, EPUB and Kindle. Book excerpt: This research project investigated important variables that impact the homogeneity and rheology of concrete mixtures. The project consisted of a field study and a laboratory study. The field study collected information from six different projects in Iowa. The information that was collected during the field study documented cementitious material properties, plastic concrete properties, and hardened concrete properties. The laboratory study was used to develop baseline mixture variability information for the field study. It also investigated plastic concrete properties using various new devices to evaluate rheology and mixing efficiency. In addition, the lab study evaluated a strategy for the optimization of mortar and concrete mixtures containing supplementary cementitious materials.

Available in PDF, EPUB and Kindle. Book excerpt: Unexpected interactions between otherwise acceptable ingredients in portland cement concrete are becoming increasingly common as cementitious systems become more and more complex and demands on the systems are more rigorous. Such incompatibilities are exhibited as early stiffening or excessive retardation, potential for uncontrolled early-age cracking, and unstable or unacceptable air-void systems. A number of test methods have been reviewed to assess their usefulness in detecting incompatibility early to help prevent problems with pavements in the field. A protocol has been developed to allow product manufacturers, concrete producers, contractors, and owners to monitor their materials and concrete systems. The protocol is phased to allow relatively simple field ttests to provide early warnings of potential problems and tthen central laboratory tests to support and confirm the field work. This is the first of two volumes. The other volume in the series is: FHWA HRT-06-080, Identifying incompatible combinations of concrete materials, volume II--Test protocol.

Download or read book Measuring Rheological Properties of Cement-based Materials written by Mohammed Sonebi and published by Springer Nature. 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.
