Abstract:
A convergent approach for using in-situ rheological and Electrochemical Impedance measurements allows for unique information about the material’s structure, hydration kinetics and evolution of rheological parameters. Nanoscale carbon fibers, due to their extraordinary intrinsic conductivity, are ideal candidates for tuning the electrical properties and hydration kinetics of complex fluids, such as cementitious nanocomposites, at fresh state. In this presentation, we will show experimentally that dielectric permittivity accurately reflects changes in rheological properties from fluid-to-solid as stiffness increases.
