Influence de la temperature de recuit sur la cinetique de l'hydratation du silicate tricalcique
1982
Abstract The tricalcium silicate annealing effect at a temperature range from 800 to 1600°C on its hydration kinetic has been studied by microcalorimetry. Only samples refired at 1000 and 1200°C show high free lime contents produced by thermal decomposition and different thermoluminescence curves; their hydration rates are also the slowest. It seems to be that not only partial thermal decomposition but also structure defects characteristics could influence the hydration rate of tricalcium silicate. Avrami's nucleation equation has been applied with success to the rising step of the calorimetric peak for every sample.
