(a) heat flow during the first 0.5 h from in situ calo, (b) heat flow during the first 6 h, (c) heat flow during the first 3 d, and (d) cumulative heat released during the first 3 d. Hydration stages of conventional OPC labeled as gray boxes; the new hydration stages with HyCon® B labeled as orange boxes. The arrow in (b) shows the extremely slow heat release during the 1st induction period with HyCon® B compared to the heat released during the conventional OPC hydration reaction. Anh. - anhydrite.
