Book excerpt: Rapid construction practices throughout the concrete industry have brought increasing pressure on specifying agencies to assess the quality of concrete at an earlier age than 7 or 28 days after placement. Currently, the later age is still specified for compression tests of 152 by 304-mm (6 by 12-in.) cylinders of concrete as delivered to the job site in order to determine quality. During the 28-day period, it is not unusual for a multistory building to rise several floors before the strength tests are conducted. This situation is considered by many to be too precarious for construction to proceed on a sound technical basis and with adequate assurance of safety. Furthermore, extensive and costly delays are encountered when 28-day test results are low, since a field investigation may be necessary to verify the load-carrying capacity of the structure. Further delay is certain if concrete must be reinforced or replaced. Conversely, economics dictate that work continue without knowing quality, thus setting the stage for a catastrophic collision between advancing construction technology and the price owners are willing to pay for their capital facilities. Surely, an earlier assessment of concrete quality is absolutely essential.

This book was released on 1970 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Statistically analyzes field strength data supplied by various organizations using the accelerated method of estimating 28-day strength of concrete. Briefly, the accelerated method consists of initial standard moist-curing of test specimens for 24 hr, followed by boiling for 3 1/2 hr, and testing in compression I hr later. The analyses of the test data indicate that the accelerated test method under discussion is an excellent means for rapid strength determination of concrete, and its use by the concrete industry is recommended"--Page 894.

Book excerpt: THIS CHAPTER DEALS WITH METHODS FOR ESTImating the potential later-age strength of a concrete mixture based upon the compressive strength measured on cylindrical specimens at early ages. The results of the cooperative research program leading to the development of ASTM Test Method for Making, Accelerated Curing, and Testing Concrete Compression Test Specimens (C 684) are reviewed. This review is based on Chapter 13 of ASTM STP 169B, which was written by M. H. Wills, Jr., and was titled "Accelerated Strength Tests." The earlier text was augmented by the current author in ASTM STP 169C by the addition of information on the high-temperature and pressure-accelerated test method that was added to ASTM C 684 in 1989. In addition, the author expanded the chapter in ASTM STP 169C by including the basis of ASTM Test Method for Developing Early-Age Compression Test Values and Projecting Later-Age Strengths (C 918). This current version updates changes to ASTM C 684 and ASTM C 918 since ASTM STP 169C was published.

Download or read book Concrete Solutions written by Michael Grantham and published by CRC Press. This book was released on 2016-09-19 with total page 1364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete Solutions contains the contributions from some 30 countries to Concrete Solutions, the 6th International Conference on Concrete Repair (Thessaloniki, Greece, 20-23 June 2016). Strengthening and retrofitting are major themes in this volume, with NDT and electrochemical repair following closely, discussing the latest advances and technologies in concrete repair. The book brings together some interesting and challenging theoretical approaches and questions if we really understand and approach such topics as corrosion monitoring correctly. Concrete Solutions is an essential reference work for those working in the concrete repair field, from engineers to architects and from students to clients. The Concrete Solutions Series of international conferences on concrete repair began in 2003 with a conference held in St. Malo, France in association with INSA Rennes. Subsequent conferences have seen the Series partnering with the University of Padua (Italy) in 2009, with TU Dresden (Germany) in 2011 and with Queen’s University Belfast (Northern Ireland) in 2014. In 2016 Thessaloniki (Greece) hosted the conference, partnering with both Aristotle University of Thessaloniki (AUTH) and Democritus University of Thrace (DUTH). The next conference in the series will be held in 2019 in Istanbul.
