Abstract
CaAl₂O₄ (CA) is the main constituent of calcium aluminate cement (CAC), which is widely used in the production of refractory castables. This research focuses on novel, timeresolved, non-destructive methods for monitoring the hydration process of CA. To achieve this, both undoped CA and samarium-doped CA were synthesized, and their structure and microstructure were analyzed using X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). SEM coupled with energy-dispersive X-ray spectroscopy (EDS) was also employed to observe the effects of CA hydration. Luminescence spectroscopy, utilizing Sm ions as an optical marker, was used to monitor the hydration behavior. A decrease in luminescence intensity observed after 24 hours indicates changes in the chemical environment associated with the hydration process. Additionally, Optically Detected Magnetic Resonance (ODMR) was used as a complementary method, employing nitrogen-vacancy (NV) nanodiamonds suspended in water as optical probes. A reduction in ODMR contrast after hydration is attributed to the formation of a fully hydrated phase and the disappearance of free ions. In summary, presented techniques offer promising, non-destructive, realtime tools for observation of the hydration processes in cement-based structures.
