The concrete industry is under increasing pressure to reduce the energy used in production of portland cement and the associated greenhouse gas emissions. There are several possible ways to address this challenge, but an optimized balance must be achieved with respect to low cost, high production, and high performance for the industry to thrive and grow to meet increasing demand. Material choices and new material development play important roles in this process. Of particular interest is the investigation of new supplementary cementitious materials (SCMs), which have the potential for great impact with low disruption. This presentation focuses on the search to broaden resources for SCMs, including calcined clays, natural mineral byproducts from other industries, and reclaimed and remediated fly ashes.


Dr. Maria Juenger received her B.S. degree in Chemistry from Duke University and Ph.D. in Materials Science and Engineering from Northwestern University. After completing her Ph.D., she was a postdoctoral researcher in Civil Engineering at the University of California, Berkeley. Dr. Juenger’s teaching and research focus on materials used in civil engineering applications. She primarily examines chemical issues in cement-based materials; these include phase formation in cement clinkering, hydration chemistry of portland cement, calcium sulfoaluminate cement, geopolymers, and supplementary cementitious materials, and chemical deterioration processes in concrete. In 2005 she received a Faculty Early CAREER Award from the National Science Foundation. She is a fellow of the American Concrete Institute and has received several of its awards for her research, teaching, and service, including the Walter P. Moore, Jr. Faculty Achievement Award in 2009, the Young Member Award for Professional Achievement in 2010, and the Wason Medal for Materials Research in 2011. She is currently serving as chair of American Concrete Institute committee 236 - Material Science of Concrete. Dr. Juenger is also a fellow of the American Ceramic Society, where she serves as Trustee of the Cements Division, and a member of RILEM.
