In this work, the effect of particle size change on the hydration behavior of a commercial calcium aluminate cement (CAC) after grinding for different times was studied. The hydration heat curves of the cements with and without milling were tested through the semi-adiabatic method, and the setting time was measured by Vicat apparatus. The vacuum freeze drying method was utilized to terminate the cement hydration at the designated time, and X-ray diffraction was conducted to analyse the phase composition of the hydrated products.
