However, most calorimetry data on the hydration of cementitious materials is reported graphically and compared qualitatively. The rarity of quantitatively analyzed heat flow data is likely due to two factors: first, no scientific consensus on the most relevant quantitative parameters and their determination has been reached (except the cumulative heat after defined time intervals), and second, it is tedious to process large amounts of calorimetry curves consistently if the processing is done manually on a file-by-file basis.
