Jie Zhang
My general research interests include
Concrete technology:
nondestructive testing in civil engineering (resistivity, ultrasonic)
Microstructure of cement-based materials:
microstructure characterization, modeling
Early age properties of cement-based materials:
hydration mechanism, material properties
My current research project is studying the early age hydration kinetics of cement under certain environmental conditions, such as the high temperature and pressure in oil wells. My goal is to predict both the setting and demolding times of cement paste with minimal information. This work follows the research done by Dr. Sulapha Peethamparan, who recently left to take an academic position in Clarkson University.
Biography
Jie joined Prof. Scherer’s group as a postdoctoral research associate in August 2008. She received her PhD in civil engineering in July 2008 from The Hong Kong University of Science and Technology. Her doctoral research work was on microstructure study of cementitious materials using resistivity measurement. Jie received her bachelor’s degree in hydraulic engineering from Tsinghua University, Beijing in June 2004.
