Nano- and Microstructural Characterization of Portland Limestone Cement Pastes

Nadelman, Elizabeth I. / Freas, Dylan J. / Kurtis, Kimberly E.

This research effort examines the rates of nano- and microstructural development in portland limestone cement pastes through Raman spectroscopy, specific surface area (SSA) analysis, and scanning electron microscopy (SEM). This paper considers the first of these techniques, evaluating chemical composition through in situ Raman spectroscopy measurements. Changes in the chemical composition of the hydrated cement paste is evaluated at various stages of hydration as a first step toward to relating compositional changes over time to rates of nano- and microstructural development. Results from this research effort will provide better insights into how changes in composition and fineness affect the rates of microstructural development in cement-based materials, which can ultimately be used to assess and predict their mechanical behavior and long-term durability.
