Finally, the degrees of hydration for each stop can be compared, depending on the activators used. As explained before, the ages at which the hydration stops were done were chosen so that the degrees of hydration r(t) calculated with Qmax 2 were identical for the three types of activation. In the end, this hypothesis seems reasonable since the NMR results, as the DOHs calculated at each stop, are similar for the three activators (0.01 for the first stop, 0.1 for the second one and 0.25 for the third one).
