Resolving manifold setting dynamics in protiated and D2O based portland cement.

Abstract: Previous NCS measurement on glass biocements revealed that setting is non-monotonic. Recent determinations using VESUVIO (2016-Apr) for Portland cements showed similar oscillatory setting-trends. Despite avoidance of H's high-scattering cross-section, D2O as mobile phase retards setting. This highlights the need to conduct complementary determinations on protiated cements, retaining relevance to the real-world systems and thus impact. Of key importance is to characterise the vibrational density of states (VDOS) of cooperative, whole-molecule motions (i.e.Low-E,THz). These are certain to change with the manifold structures over setting profiles – particularly at the forming interfaces, providing an avenue to track and characterise setting progression and related mechanical properties. MERLIN represents an excellent choice for characterising such cooperative dynamics in the 10-160meV range
