P MehtaP. Kumar Mehta (Berkeley, CA) is a Professor Emeritus in Civil and Environmental Engineering at the University of California at Berkeley. Before his retirement, he held the Roy W. Carlson Distinguished Professorship. His educational backgroundincludes an undergraduate degree in chemical engineering from Delhi (India), M.S. in ceramic engineering from North Carolina State University and Doctor of Engineering in material science and engineering from the University of California, Berkeley. He developed fundamental research on the cements and he is a world expert in the development of "green concrete." Paulo J. M. Monteiro (Berkeley, CA), professor and group leader of the Structural Engineering Mechanics and Materials Group, Department of Civil and Environmental Engineering at the University of California at Berkeley, received his engineering degree from the University of Sao Paulo and master and Ph.D. degrees from U.C. Berkeley. Dr. Monteiro's professional experience includes working on a number of projects using mass concrete. Recent projects include working with roller-compacted concrete and architectural concrete. At U.C. Berkeley, he and his students are creating micromechanical models, characterizing deleterious reactions in concrete, and developing new microscopic techniques, such as low-temperature scanning electron microscopy, soft x-ray microscopy, and direction cooling. Dr. Monteiro has published over one hundred articles in archival journals. Read More Read Less
