Preface

In response to the enactment by the U.S. Congress of the Intermodal Surface Transportation Efficiency Act (ISTEA), the Federal Highway Administration (FHWA) requested that the National Research Council (NRC) conduct a study on nonconventional concrete technology for renewal of the highway infrastructure. ISTEA directed the FHWA to initiate a comprehensive, long-range infrastructure research and development (R&D) program. Since current research in the field has tended to concentrate on modifications or refinements of traditional concrete technologies, the Office of Advanced Research of the FHWA requested the NRC undertake this study in order to access the broad expertise in materials science of the National Materials Advisory Board (NMAB) to help identify truly innovative materials and procedures that may not have been previously considered.

The NMAB convened the nine-member Committee on Nonconventional Concrete Technologies for Renewal of the Highway Infrastructure to conduct this study. The objectives of the study were to look beyond near-term developments in concrete technology to identify innovative materials and procedures that have the potential to accelerate the highway construction process, improve the durability of highway pavement and bridges, and enhance their serviceability and longevity under adverse conditions. To ensure that new perspectives on possible future R&D directions were included and that the widest spectrum of fields within materials science was accessed, five distinguished scientists with little previous experience in infrastructural materials R& D were named to the committee. Their expertise ranges from ceramics and biomimetics to metallurgy and geopolymer science. The other four committee members have extensive expertise in conventional concrete technology, structural engineering, or architectural design, and provided an informed perspective on the constraints,

problems, and priorities of infrastructural materials R&D as well as background information on current R&D programs.

The committee defined the idea of designing “nonconventional concrete” as taking current knowledge and experience about concrete technology —its service requirements and its limitations—and going “back to the drawing board.” The committee believed that by incorporating current ideas and understanding of both advanced structural and natural materials with possible materials-science systems approaches, it would be possible to identify nonconventional technologies with distinct advantages over conventional concrete. The committee did not consider possible nonconventional remediation or repair techniques, since this would have increased the scope of the study tremendously. The committee also did not consider the question of potential increases in initial cost for implementing nonconventional techniques. The committee believed that cost arguments would have detracted from the central objective of the report and would have been beyond the resources and expertise of the committee, since the cost of innovative materials and processes must be viewed within the construct of the total life-cycle of the structure and not simply from the perspective of the lowest cost for original construction.

To access the many disciplines incorporated in materials science and engineering, and compile the ideas and data required for this study, the committee organized a two-day workshop. In addition to the committee, the workshop was attended by twenty individuals with expertise in solid state physics, electrochemistry, metallurgy, ceramics, biological systems, geological systems, microstructural modeling, microwave processing, polymer science, structural engineering, civil engineering, and concrete research and practice. The emphasis of the workshop was on postulating innovative areas of long-term research that have high-payoff potential. The attendance roster for the workshop is presented in Appendix A.

The results of the workshop and the expertise of the committee were then used as the basis for the composition of this report. The report is divided into five chapters. Chapter 1 provides a short tutorial on conventional concrete from both a materials-science perspective and a systems approach perspective. The chapter also discusses the advantages and disadvantages of the current technology and presents the characteristics of an “ideal” concrete. Chapter 2 focuses on the potential methods for manipulating the microstructure and chemistry of the concrete system to improve the processing and properties of the material. Chapter 3 discusses potential nonconventional reinforcement

systems for concrete. Chapter 4 examines concrete processing technologies. Chapter 5 integrates the information presented in the previous chapters to demonstrate the interrelationships among the different components of concrete technology and the importance of the materials-science systems approach to concrete research.

Acknowledgments

This study was exciting because it challenged experts in a variety of fields to cross intellectual boundaries and think innovatively about concrete technology. The experts agreed to undertake this challenge for no reason other than their own intellectual curiosity and their desire to aid the development of new infrastructural materials and techniques. The committee is grateful for all the help it received and expresses its thanks to everyone who participated. Without the patience and support provided by many individuals and organizations, this report could never have been completed.

In particular, the committee thanks Herbert A. Franklin of Bechtel Corporation. His support as technical advisor to the committee was invaluable. He provided great insight and made significant contributions to the report. Harold Jabloner of Hercules, Incorporated, and Youjiang Wang of the Georgia Institute of Technology should also receive special thanks for their participation and insight while working with the committee.

The committee is grateful for the dedication of Richard A. Livingston of the Federal Highway Administration for his vision and assistance to the committee. Jeff W. Rish of Wright Laboratories also provided valuable insight.

This study relied heavily on the information collected from a range of materials-science experts at an international workshop that the committee organized. The committee is grateful to all of the participants, who provided the balance of expertise, insight, and originality needed to develop and scrutinize ideas about potentially new and innovative nonconventional concrete technologies. A complete list of workshop participants can be found in Appendix A.

The committee also thanks the staff of the National Materials Advisory Board, particularly Robert M. Ehrenreich, senior program

manager, and Pat Williams, senior project assistant. The committee also thanks Bonnie Scarborough, Charles Hach, and Jack Hughes.

Finally, the chair of the committee expresses her appreciation of the study members for their dedication and patience during the course of this study. This report could never have been completed without their diligence and goodwill. However, she would like to specifically note that Robert M. Ehrenreich did a superb job in shepherding the committee through the process of transforming nine independent and willful minds from nine diverse disciplines into a working, focused unit. On a personal note, she is particularly thankful to him and Norbert S. Baer for their support during the course of the study.
