Effect of recrystallization in tricalcium silicate hydrate according to1H NMR spin-relaxation data

Tricalcium silicate hydrate 3CaO'SiO2"I.5H20 (TSH) is one of the principal minerals of cement stone. According to the data from ZH NMR spectroscopy in [i], the hydrogen atoms in TSH appear in the composition of molecules of water of crystallization located in channels in the structure extending along threefold axes [2]. Since the dynamics of the water molecules underlie the hydration and hardening processes of calcium silicates [3], it is important to obtain its microscopic characteristics.
