Book Synopsis Entrained Air-void Systems for Durable Highway Concrete by : Peter Clement Taylor
Download or read book Entrained Air-void Systems for Durable Highway Concrete written by Peter Clement Taylor and published by . This book was released on 2021 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory testing and field experience have shown that highway concrete should be properly air entrained to resist the action of freezing and thawing, particularly in wet climates. Several gaps in the state of the knowledge still exist. The TRB National Cooperative Highway Research Program's NCHRP Research Report 961: Entrained Air-Void Systems for Durable Highway Concrete addresses these gaps and, more specifically, investigates innovative test methods for effectively characterizing the air system in fresh concrete and identifying the characteristics of the air-void system that are related to the performance of field concrete under freeze-thaw conditions. Appendices A -G provide further details on the different aspects of the research performed for this project.

Book Synopsis Field Study of Air Content Stability in the Slipform Paving Process by :
Download or read book Field Study of Air Content Stability in the Slipform Paving Process written by and published by . This book was released on 2012 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the impacts of construction on the air content and air-void system structure of Portland cement concrete pavements. The primary intent was to quantify the air content of fresh concrete before and after it has gone through the slipform paver. The air-void system parameters of hardened concrete were then assessed using cast and extracted core specimens. The results of the air content testing on fresh concrete and the concrete cylinder specimens cast in the field suggested that there is some loss of air as the concrete passes through the paver. Laboratory testing performed on cores extracted from the pavement did not provide any conclusive evidence that entrained air is lost during the slipform paving process. In fact, many of the extracted cores had measured air content values that were much higher than the specification requirement. If excessive, this could result in increased permeability and low-strength related issues. Although a rigorous statistical analysis was not performed, the results suggest that the air content testing on fresh concrete is not capturing the true air content of the concrete placed with a slipform paver. The fresh concrete air content is generally lower than the air content measured in the cores.
Book Synopsis Air Voids in Concrete and Characteristics of Aggregates by : National Research Council (U.S.). Highway Research Board
Download or read book Air Voids in Concrete and Characteristics of Aggregates written by National Research Council (U.S.). Highway Research Board and published by . This book was released on 1958 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: A study of carbonate rocks used for concrete aggregate was conducted for the Iowa State Highway Commission to determine the factors in the aggregate causing distress in concrete and to establish criteria for recognizing potentially poor aggregates. Paper 2: The theory of the action of entrained air in producing frost-resistant concrete demonstrates the importance of the size and distribution of the air voids in the Portland cement paste. Paper 3: A summary of the results of the chemical study of carbonate rocks from several quarries in Northeast Iowa which produced carbonate aggregate for highway pavement concrete is presented.

Book Synopsis Concrete Admixtures Handbook by : V.S. Ramachandran
Download or read book Concrete Admixtures Handbook written by V.S. Ramachandran and published by William Andrew. This book was released on 1996-12-31 with total page 1183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition ten years ago, significant developments have occurred in the use of admixtures in concrete. Eight new chapters and a full update of the preceding ten chapters bring this book up to date; reflecting the relative advances made in the science and technology of different groups of admixtures. The increased role and development of admixtures in concrete technology is evidenced by a number of conferences, publications, and novel admixtures available in the market place. These developments in the field caused the modification of many chapters in the first edition in order to reflect the advances. Although individual chapters refer to standards and specifications of admixtures, those only interested in the standards or techniques used in investigating admixtures will find the second chapter (Research Technologies, Standards, and Specifications) useful. Admixtures are not as inert as may be presumed. They may chemically interact with the constituents of concrete and affect the properties of the fresh and hardened concrete and its durability. The third chapter deals with these aspects. It was important to devote a chapter to recent attempts in developing new admixtures.
