The kinetics of early hydration reactions of Dyckerhoff G-oil cement and its blends using conduction calorimeter and thermogravimetric analysis are reported in the present paper. The coupling effect of temperature (25, 40, 50, 60, 80 degrees C) and material composition (100, 95, 90, 85, 80, 75, 70, 65% Dyckerhoff) with different substitution levels by blast slag furnace, metakaolin and limestone were analyzed on the light of hydration products and activation energy of different reactions. Besides the initial peak in the first 10 min of hydration, two or more other particular peaks characterizing the sequence of successive hydration reactions of the cement are observed, the intensities and the time position of which depend on the temperatures and on the composition of the materials. The apparent activation energies calculated from the hydration peaks characterizing the different reactions decrease with the increase in the substitution levels, but that of the second peaks (31.95 to 33.31 kJ mol(-1)) is higher than that of the former (27.88 to 31.33 kJ mol(-1)) at the same level of substitution. Thermogravimetric analysis of the samples after calorimetric measurement shows that the main hydration products are C-S-H, C-A-S-H, CH, and calcium carbonate. Their quantity depends on the material composition of the material and the temperatures of hydration.
