Available in PDF, EPUB and Kindle. Book excerpt: To study self-consolidating concrete it is important to be able to characterize segregation resistance. In this paper, a segregation probe is introduced as a simple and fast method for testing static segregation of fresh concrete. The results of the segregation probe tests were verified using image analysis. A mechanics analysis was used to estimate the forces acting on the segregation probe and explain why the thickness of a paste/mortar layer at the surface of the concrete can be measured. Finally, use of the probe to determine robustness is presented.

Book Synopsis Proposing a New Apparatus to Assess the Properties of Self-Consolidating Concrete by : Mahmoud Nili
Download or read book Proposing a New Apparatus to Assess the Properties of Self-Consolidating Concrete written by Mahmoud Nili and published by . This book was released on 2020 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing a quick and low-disturbance method that allows quantification of the fresh properties of self-consolidating concrete (SCC), such as filling ability, passing ability, and segregation resistance, is in high demand. Some apparatuses that measure only one property of SCC have been developed so far, so there is no apparatus for simultaneous measurement of all SCC properties. In the present article, a new apparatus that can rapidly assess the aforementioned properties at the same time was proposed. In order to evaluate the performance of the new apparatus, seven different SCC mixtures were prepared, and their fresh properties were experimentally analyzed. One common test for each property of SCC was also performed to verify the results. The results of this article revealed that the results obtained of fresh properties by the new apparatus were in a good agreement with those measured by the traditional methods. As a result, the proposed apparatus may be an appropriate substitution for determination of all SCC properties.
Book Synopsis Predicting Dynamic Segregation of Self-Consolidating Concrete from the Slump-Flow Test by : Nathan Tregger
Download or read book Predicting Dynamic Segregation of Self-Consolidating Concrete from the Slump-Flow Test written by Nathan Tregger and published by . This book was released on 2010 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two key characteristics of self-consolidating concrete are flowability and segregation resistance. Quality control of flowability is typically predicted by the final diameter of the slump-flow test. In this paper, experimental results demonstrate that dynamic segregation of a self-consolidating concrete mix can also be predicted from the slump-flow test by measuring the time it takes for the flow to reach its final diameter. For a constant final diameter and aggregate content, increasing the time to final diameter led to a more stable mix. Two sets of slump-flow and segregation data were obtained for flow diameters of 65 and 70 cm, both with constant water-to-binder and aggregate-to-binder ratios. Dynamic segregation was determined by comparing the aggregate content in three regions: Within the diameter of the slump cone, between the diameter of the cone and a diameter of 50 cm, and between a diameter of 50 cm and the final diameter. In addition, the rapid penetration test was used to compare dynamic and static segregation characteristics.
Book Synopsis The Comparison and Introduction of Plate Test and Electrical Resistance Methods of Determining the Setting Time and Thixotropy of Self-Consolidating Concrete by : Ali Akbar Shirzadi Javid

This book was released on 2020 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Setting time and rheology of mixtures are among the most important features in new generation concretes such as self-consolidating concrete (SCC) and can have a great impact on the behavior of fresh concrete. Therefore, introducing new methods for determining these parameters has always been one of the main concerns. In this research, we tried to determine a relationship between the measured setting time from the ASTM C403/C403M-08, Standard Test Method for Time of Setting of Concrete Mixtures by Penetration Resistance Method , and the electrical resistance (ER) method, as well as the rheological parameters, including dynamic and static yield stress. Also, a new method for determining the setting time and concrete thixotropy--called the plate test method--is introduced and validated. The results indicated that the ER method is an accurate one in determining the initial and final setting time of SCC mixtures. Concrete mixtures with higher yield stress (static and dynamic) have a shorter setting time. Investigating the results indicated that the higher the static yield stress mean of the mixture in the time period of thixotropic behavior, the shorter the initial setting time. Therefore, increasing static yield stress is associated with a reduction in the setting time. In the case of dynamic yield stress, similar events occurred with static yield stresses, and an increase in this stress and its growth rate was associated with a reduction in the initial setting time. Furthermore, the results obtained by the new method (plate method), along with the results of rheology parameters measured by the rheometer device, indicated that the difference between results was in the range of 4 to 11 %. Also, the difference in the setting time obtained from the plate method in comparison with the penetration resistance method was 9 % at maximum. These results indicated that the plate test method has an acceptable accuracy in measuring the setting time and thixotropy.

Available in PDF, EPUB and Kindle. Book excerpt: Data from two research projects were analyzed to evaluate the suitability of seven empirical workability test methods for self-consolidating concrete (SCC)--namely, the column segregation test, J-ring test, L-box test, penetration apparatus test, sieve stability test, slump flow test, and V-funnel test. The results of these empirical tests were compared to rheometer measurements. Test methods were evaluated based on (1) the extent to which each method independently indicated filling ability, passing ability, or segregation resistance and (2) the ease and simplicity with which each test method can be used on a routine basis in the laboratory or the field. The data set consisted of 286 SCC mixtures incorporating a range of materials, mixture proportions, and workability characteristics. It was determined that the slump flow test should be used for filling ability, the J-ring test for passing ability, and the column segregation test or sieve stability test for segregation resistance.

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.
