✦ Synopsis

The early stages of cement hydration were investlgated by proton spinspin relaxation time (T c) measurements because these experiments can be performed much faster (in several seconds) than the characterlstlc time for a change in hydration evolution.

In addition, comparing the free induction decays of nuclear magnetization and its spln echoes allows the separation of solld-llke and llquld-llke proton groups. The values of T and the associated magnetization fractions were monitored for cement ~astes with different water/cement ratlos In the first 20 hours of hydration.
