Abstract
The proton spin-spin NMR relaxation is monitored in white cement as a function of hydration time. The multiexponential relaxation behavior is resolved and the fractional magnetizations T2 and the corresponding magnitudes are also reported. By monitoring the free induction decay and spin-echo envelope with the Meiboom-Gill modified Carr-Purcell pulse sequence, during hydration, information about growth patterns of various cements is obtained. In particular, the secondary hydration water is characterized through direct observation, and a relatively immobile, near solidlike water phase, observed for the first time in hydrating cement is observed.
