Different characteristic parameters like the time of maximum heat flow, the dormant period's duration, or the silicate reaction's maximum heat flow can be obtained from experimental heat flow curves (see Figure ). As mentioned in the introduction, two quantitative methods are described in standards: a) the calculation of the cumulated heat at defined time intervals (most often 7 days) and b) the extraction of the setting time from the heat flow curve by determining the time when the heat flow reaches 50% of the maximum average heat flow (ASTM C1679). If this data needs to be acquired for many heat flow curves, determining these parameters becomes tedious if the analysis is not automated. Here, we demonstrate the automatic determination of characteristic parameters from isothermal calorimetry data.
