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
The temperature dependences of the proton spin-lattice, Tt, and spin-spin, T2, relaxation times of isotactic polypropylene films with different thermal histories and atactic fraction were investigated. A T~ minimum occurs for both melt-quenched and annealed samples at about 70°C. It shifts to lower
