Abstract
In this work, the effect of particle size of calcium aluminate cement (CAC) on its hydration products during hydration at 40 ℃ was studied. The cement hydration at the designated times was terminated by the freeze-vacuum method. The phase development and microstructure evolution during the cement hydration were investigated by XRD and SEM, respectively. It was found that the quantity and the degree of crystallinity of C3AH6 increases with the reducing particle size of CAC after hydration at 40 ℃. Moreover, the mechanism of such phase development was discussed. |
