Shiho Kawashima’s research interests are in cement and concrete science. In particular, she is interested in characterizing and tailoring the rheology (or flow behavior) of fresh cement-based systems to improve the concrete casting process. Over its lifetime, concrete transitions from behaving as a viscoelastic fluid-like material to a rock-like solid. And although the first phase is fleeting compared to the latter (hours versus decades), this earlier life period is intimately tied to materials processing. Therefore the corresponding rheological properties are critical in determining the feasibility and efficiency of the placement process during construction, as well as the eventual performance of the structure in place. In addition, Kawashima is interested in other materials science aspects of cement-based materials, including nano-/microstructural characterization and modification, to improve their properties for various applications.
In particular, Kawashima’s interest and expertise is in the development of characterization techniques to probe the viscoelastic properties of fresh cement-based systems and the design of these systems to facilitate various construction applications. For instance, 3D concrete printing presents the advantage and challenge of casting form-free and vibration-free, compared to conventional static casting techniques. Therefore the rheological and solidification properties must be precisely controlled, which Kawashima’s work aims to do.
Kawashima received a BS in civil engineering and engineering mechanics from Columbia University in 2003, an MS in structural engineering and materials from Northwestern University in 2009, and a PhD in structural engineering and materials from Northwestern University in 2012. She is a member of American Concrete Institute, involved in committees 236, 237, 238, 238-A, and 241.
