Proton NMR relaxation study of calcium aluminate hydrates was performed. The proton spin-lattice relaxation time (Tl,ef) was measured as a function of curing time at room temperature and at 65Β°C, respectively. At both temperatures a continuous decrease of Tl,efwith time was observed in the initial c
Hydrated aluminophosphate AIPO,-8 has been studied by fast "AI magic-angle-spinning (MAS) NMR at 4.7 and 9.4 T, 'H-\*'AI MAS NMR with cross-polarization (CP/MAS) and by quadrupole nutation NMR. The material contains four and possibly five crystallographically inequivalent sites for aluminium
