ABSTRACT:
A method for measuring or predicting a property of a porous material while curing, the porous material including therein a liquid which undergoes metamorphosis and which is present in the porous material in different phases during curing, the method including the steps of performing a low frequency, spin-echo nuclear magnetic resonance (NMR) measurement of each phase of the liquid, and correlating the NMR measurement, or extrapolating the property, in accordance with a predetermined relationship between the property and the NMR measurement.
