AbstractTricalcium silicate, tricalcium aluminate and tricalcium aluminate + gypsum were hydrated in the presence of 5-50 percent CaCO03 for different lengths of time (a few minutes to 28 days) and the products were examined by differential scanning calorimetry (DSC), differential thermogravimetry ( DTG), differential thermal analysis (DTA) and conduction calorimetry. On the basis of the results a mechanism has been proposed to explain the effect of CaCO3 on the hydration of cement.
