Effects of Texas Fly Ash on Air-Entrainment in Concrete: Comprehensive Report

This report summarizes a comprehensive joint research project, funded by the Texas Department of Transportation (TxDOT) and performed by researchers at the University of Texas at Austin and Cornell University. This three-volume report is perhaps the most complete study to date on this topic. It is expected that the key findings from this study will be of benefit to practitioners in Texas and beyond. The report includes the following three volumes: Volume 1 (Chapters 2–9)—“Evaluating the Influence of Fly Ash on Air-Entrained Concrete,” based on Nathan Harris’s Ph.D. Dissertation at Cornell University (2007); Volume 2 (Chapters 10–17)—“The Effects of Fly Ash on the Ability to Entrain and Stabilize Air in Concrete,” Tyler Ley’s Ph.D. Dissertation at the University of Texas at Austin (2007); and Volume 3 (Chapters 18–24)—“Clustering of Air Voids around Aggregates in Air- Entrained Concrete,” Andrew Naranjo’s M.S. Thesis at the University of Texas at Austin (2007). A brief concluding chapter is presented that summarizes the key findings and recommendations and identifies future research needs.
