This book was released on 1962 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: Development of high early strength is desirable to the manufacturers of precast and prestressed concrete units, which often require expensive forms or stress beds. Steam curing accelerates the gain in strength at early ages, but the uncontrolled use of steam may seriously affect the growth in strength at later ages. Paper 2: The discovery that concrete aggregates were not inert but could participate in chemical reactions with certain cement compounds stimulated an international research effort that has resulted in the recognition of several distinct mechanisms by which these reactions may reduce the durability of concrete. Recently, attention has been drawn to a reaction involving the cement alkalies and a type of argillaceous dolomitic limestone.

Book Synopsis The Effect of Steam Curing on High-Early Strength Portland Cement Containing Carbonate Addition by : C. Bédard
Download or read book The Effect of Steam Curing on High-Early Strength Portland Cement Containing Carbonate Addition written by C. Bédard and published by . This book was released on 1990 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1981 the Canadian Standards Association (CSA) Committee A5 on Hydraulic Cements approved carbonate addition to normal portland cement Type 10 to a maximum of 5%. The decision was based on a considerable amount of data indicating no adverse effects on the properties of concrete and even improvements at optimum level of carbonate addition. The CSA Committee is now considering a proposal for extending carbonate addition to high-early strength portland cement Type 30 that has essentially the same chemical composition as Type 10 cement. Since Type 30 cement is used primarily in precast and prestressed concrete operations, a project has been initiated at the Research and Technical Center of Lafarge Canada Inc. to study the effect of steam curing conditions on the properties of concrete made with Type 30 cement containing carbonate addition. The main parameters will be the tricalcium aluminate (C3A) content of the cement, the presence of carbonate addition, and the curing temperature. The properties investigated will be compressive strength, freezing and thawing resistance ASTM Test for Resistance of Concrete to Rapid Freezing and Thawing (C 666, Procedure A), and volume change ASTM Test for Length Change of Hardened Hydraulic Cement Mortar and Concrete (C 157).
Book Synopsis Alkali-Aggregate Reaction in Concrete by : Ian Sims
Download or read book Alkali-Aggregate Reaction in Concrete written by Ian Sims and published by CRC Press. This book was released on 2017-08-01 with total page 1044 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alkali-Aggregate Reaction in Concrete: A World Review is unique in providing authoritative and up to date expert information on the causes and effects of Alkali-Aggregate Reaction (AAR) in concrete structures worldwide. In 1992 a first edition entitled The Alkali-Silica Reaction in Concrete, edited by Professor Narayan Swamy, was published in a first attempt to cover this concrete problem from a global perspective, but the coverage was incomplete. This completely new edition offers a fully updated and more universal coverage of the world situation concerning AAR and includes a wealth of new evidence and research information that has accumulated in the intervening years. Although there are various textbooks offering readers sections that deal with AAR deterioration and damage to concrete, no other single book brings together the views of recognised international experts in the field, and the wealth of scattered research information that is available. It provides a ‘state of the art’ review and deals authoritatively with the mechanisms of AAR, its diagnosis and how to treat concrete affected by AAR. It is illustrated by numerous actual examples from around the world, and comprises specialist contributions provided by senior engineers and scientists from many parts of the world. The book is divided into two distinct but complementary parts. The first five chapters deal with the most recent findings concerning the mechanisms involved in the reaction, methods concerning its diagnosis, testing and evaluation, together with an appraisal of current methods used in its avoidance and in the remediation of affected concrete structures. The second part is divided into eleven chapters covering each region of the world in turn. These chapters have been written by experts with specialist knowledge of AAR in the countries involved and include an authoritative appraisal of the problem and its solution as it affects concrete structures in the region. Such an authoritative compilation of information on AAR has not been attempted previously on this scale and this work is therefore an essential source for practising and research civil engineers, consultant engineers and materials scientists, as well as aggregate and cement producers, designers and concrete suppliers, especially regarding projects outside their own region.

Available in PDF, EPUB and Kindle. Book excerpt: It has long been recognized that no aggregate is completely inert in the environment of portland cement paste. This environment is always at least as alkaline as a saturated solution of calcium hydroxide and may for certain sources of cement exceed this alkalinity [1]. We only need to consider those reactions which take place at a rate sufficient to affect the concrete during its normal life span. Carbonate aggregate reactions may be beneficial, innocuous, or deleterious.

Book Synopsis The Effect of Secondary Ettringite Formation on the Durability of Concrete by : Robert L. Day
Download or read book The Effect of Secondary Ettringite Formation on the Durability of Concrete written by Robert L. Day and published by Portland Cement Association. This book was released on 1992 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report comprises a review and analysis of the available literature pertaining to the causes, effects and prevention of secondary (delayed) ettringite in concrete . Over 300 publications have been examined . Case studies of damage in concrete possibly caused by secondary ettringite formation are examined first. Fundamental research on secondary ettringite formation, its chemistry, and deposition mechanisms is then reviewed. Key investigations on the topic are analyzed in detail. Next, the potential importance of (a) method of heat-curing and (b) the chemistry of cement is outlined. In the final chapter, a rapid test for evaluation of potential secondary ettringite susceptibility (the "Duggan" test) is evaluated. The analysis indicates that there appears to be a potential for a secondary ettringite formation problem in North America; it is highly probable that secondary ettringite formation can lead to significant deterioration of heat-treated concrete. However, it is unlikely that secondary ettringite formation is, or will be, the sole mechanism responsible for premature deterioration. The critical factors that determine extent of damage due to secondary ettringite formation are (a) duration of delay period before heating the concrete; (b) severity of the heating and/or cooling regime ; and (c) the SO3/A1203 ratio of the cement. There is no evidence that nonheat-treated concrete is susceptible to this phenomenon. Further research and improvements to the Duggan test may result in the development of a useful standard test method to assess the long-term dimensional stability and durability of concrete.
