B. Bresson et H. Zanni, PRESSURE AND TEMPERATURE INFLUENCE ON TRICALCIUM SILICATE HYDRATION -A H-1 AND SI-29 NMR-STUDY, Journal de chimie physique et de physico-chimie biologique, 95(2), 1998, pp. 327-331
Hydration of tricalcium silicate with and without ground quartz, at hi
gh temperature (120 degrees C-160 degrees C) and high pressure (1000 b
ars), has been studied by Si-29 and H-1 CRAMPS NMR. Cross-polarization
, for long contact times, allows to separate crystalline phases from p
oorly crystallized hydrates and to detect small amounts of the crystal
line phases. The influence of pressure is also studied by cross-polari
zation.
