A modular 3D printed isothermal heat flow calorimeter for reaction calorimetry in continuous flow

The presented continuous flow calorimeter enables process understanding of novel flow syntheses and the use of highly reactive compounds. Adaptation of the calorimeter is possible via 3D printing and due to its modular and expandable design.

Monitoring the course of early-age reactions in alkali activated aluminosilicates

In this paper the reaction heat development of alkali activated aluminosilicates is studied by an isothermal heat flow calorimeter. The highest reaction activity is observed during two hours after mixing. The hydration heat power at early time is influenced mainly by the composition of tested mixtures involving ceramic dust as precursor and different amounts of sodium hydroxide and water glass as activators and by temperature.
