Talk Title: Thixotropy of Fresh Cement-Based Systems
Abstract: Over its lifetime, cement-based materials transition from behaving as a near-Newtonian fluid to a viscoelastic fluid-solid to eventually a rock-like solid. And although the first two phases are fleeting compared to the third phase, this earlier life period is intimately tied to materials processing.
Therefore the corresponding properties are critical in determining the efficiency of the placement process during construction, as well as the eventual performance of the structure in place. This requires that the rheological properties of the material be well characterized and controlled. During placement the material undergoes a wide range of deformations -“ very large during processes such as pouring and pumping, but then diminishingly small after placement when it is essentially at rest. This talk will cover studies that investigate the specific rheological aspect of thixotropy in cement paste and mortar systems that incorporate highly-purified attapulgite clay through static shear and dynamic rheological protocols that span wide timescales and magnitudes of deformations and rates.
Biography:
Shiho Kawashima is an Assistant Professor of Civil Engineering and Engineering Mechanics at Columbia University. Her work is in experimental cement and concrete research, which aims to tie nano-microstructural behavior to macroscale structural response. She specializes in cement rheology, particularly in the development of innovative measurement techniques to further the understanding of the structural and temporal evolution of the fresh-state microstructure of cementitious systems. She is also interested in the design of nanocomposites and sustainable infrastructural materials. She received her B.S. in Civil Engineering and Engineering Mechanics at Columbia University, and her M.S. and Ph.D. in Civil Engineering at Northwestern University.

Talk Title: A Balancing Act: Assessing the Fate of Emerging Contaminants in Urine-Derived Fertilizers that Reduce Nutrient Loads and Achieve Nutrient Recovery
Abstract:
Source separation of urine provides benefits over traditional wastewater nutrient management including providing urine-derived fertilizer and reducing nutrient loads to wastewater treatment systems. This talk reviews an evaluation of the largest known community-scale and office-scale urine separation programs in the US. Urine is collected from public events and used to fertilize crops (lettuce and carrots). The urine used for this study was well characterized for nutrient, biological, and pharmaceutical constituents. While the study is underway, this presentation will highlight results to date that focus on the effectiveness of different processing methods (storage, pasteurization, and struvite precipitation) on reducing emerging and traditional contaminants that could have an impact on public health. The potential impacts of separating urine at the source and making it a valuable product are discussed.
Biography: Dr. Nancy Love is a professor of Civil and Environmental Engineering at the University Michigan. She served as chair of the department from January 2008 -“ August 2011. In September 2011, she became Associate Dean for Academic Programs and Initiatives in the Rackham School of Graduate Studies at the University of Michigan. Prior to 2008, Dr. Love was an Assistant, Associate and Full Professor of Civil and Environmental Engineering and an Adjunct Professor of Biological Sciences at Virginia Tech. Her research focuses on environmental biotechnology and water quality with an emphasis on engineered treatment systems. Her specific interests focus on the fate of stressor chemicals in these systems, the use of technologies to sense and remove these chemicals, and on resource recovery from wastewater. Dr. Love has B.S. and M.S. degrees in Civil Engineering from the University of Illinois, a Ph.D. in Environmental Systems Engineering from Clemson University, and is a licensed professional engineer (P.E.) in the state of Michigan. After completing her M.S. degree, she worked as a process design engineer for approximately 3 years for CH2M Hill, Inc.
