Abstract

Cement hydration kinetics are controlled by clinker composition, water addition, sulfate availability and fineness. The analytical access to the first hour of hydration is limited. Here a new setup is introduced to record the initial 30-60 minutes of hydration on a routine basis with isothermal calorimetry. Fast isothermal calorimetry is fully quantitative. Reproducibility is reported in terms of thermal power of the initial peak (CoV < 1.9%) and cumulative heat release after 10-120 min (CoV < 1%). Experiments with variable sulfate and SCM addition confirm the plausibility of the results and outline future applications. The fully automated system and its fast data assessment facilitates application for process control to improve... (More)

Reproducibility is reported in terms of thermal power of the initial peak (CoV < 1.9%) and cumulative heat release after 10-120 min (CoV < 1%). Experiments with variable sulfate and SCM addition confirm the plausibility of the results and outline future applications. The fully automated system and its fast data assessment facilitates application for process control to improve consistency and to minimize cost and emissions. Hourly corrective actions are possible for sulfate addition, SCMs, separator settings and clinker reactivity.
