The kinetics of hydration and setting of cement are important for the ease of placement and for the subsequent evolution of properties. We are interested in modeling and measuring the rates, and understanding the early structural development. This research began with the efforts of post-doctoral researchers Sulapha Peethamparan and Jie Zhang, with important contributions from undergraduate Emily Weissinger. Our work on chemical shrinkage was done with a novel system invented by Joe Vocaturo. Now we are investigating the impact of fly ash on the behavior of concrete, through the research of Lori Tunstall and post-doctoral researcher Priscilla Fonseca.
