Use: An isothermal calorimeter is commonly used to determine the heat released from the cement hydration. A small cement paste/mortar sample is poured in a glass ampoule and then placed in the calorimeter. The heat released is compared to that released from an inert sample. This technique allows for the assessment of the extent of cement reaction with water, and therefore permits to evaluate the effect that other cementitious materials and admixtures have on the cement reaction.
