Influence du millieu de trempe sur la cinetique d'hydratation du silicate tricalcique

Abstract Two samples of tricalcium silicate, one air quenched, the other by means of liquid nitrogen, show different structure defects detected by thermoluminescence. Their hydration kinetics, followed by isothermal microcalorimetry and thermogravimetric analysis, point out that the fastest quenching (liquid nitrogen) induces the highest hydration rate and demonstrate once again the part played by structure defects on the reactivity.
