Non-Destructive Measurement of Chloride Profiles in Cementitious Materials Using NMR
In order to measure non-destructively the 35Cl in cementitious materials a special NMR setup was developed. Besides 35Cl also quasi-simultaneously both 23Na and 1H can be measured. This setup is built around a 4.7 T wide bore superconducting magnet. The present results show that using this setup we can measure non-destructively the 35Cl, 23Na and 1H in ordinary Portland cement samples. Using the present setup 35Cl, 23Na and 1H profiles can be measured over a longer period of time, hence giving for example the possibility to look at the dynamic binding process of 35Cl and 23Na during hydration, as is demonstrated. Moreover, the measurement time with the present setup gives the possibility to look at the dynamics processes like, for example, the NaCl solution absorption as is demonstrated, showing NMR can be used for non-destructive evaluation.
