Abstract	Hydration products formed at different periods in mixtures containing C3A with either or both CaSO4 2H2O (0.12.5,25%) and CaCO3 (0, 12.5, 25%) were followed by differential scanning calorimetry and thermogravimetry. Depending on the length of hydration, different products were formed. Calcium carbonate retards or suppresses formation of the cubic aluminate hydrate in the hydration of C3A, but it accelerates the formation of ettringite and its conversion to the monosulfoaluminate phase in the hydration of C3A+gypsum.
