Synchronous Monitoring of Cement Hydration and Polymer Film Formation Using 1H‑Time-Domain-NMR with T 2 Time-Weighted T 1 Time Evaluation: A Nondestructive Practicable Benchtop Method

For this reason, the hydration process and the film formation were simultaneously monitored. This scientific issue...

Summary:The interactions between latex and cement are still not completely understood. In this work, we would like to address the temporal changes in cement hardening and latex film formation. For this reason, the hydration process and the film formation were simultaneously monitored. This scientific issue is even more challenging as a nondestructive quantitative analysis of the film formation process is not available yet. Here, we report on simultaneous monitoring of the latex film formation and the phase development in cementitious systems via 1H-time-domain-NMR for the first time. The obtained results were validated using classical analytical methods, such as in situ X-ray diffraction, X-ray fluorescence (Rietveld analysis), and confocal laser scanning microscopy.
