TBTSHR-650D heat of hydration is based on the gass law of thermochemistry, that is, the thermal effect of a chemical reaction is only related to the initial state and final state of the system and has nothing to do with the reaction path.
It is proposed under the condition of a certain temperature around the calorimeter Unhydrated cement and cement of a certain age of hydration are respectively dissolved in a certain concentration of standard acid, and the difference between the measured heat of dissolution is the heat of hydration released by the cement during the specified age.
The Cement Hydration Heat Tester is mainly used to determine the heat of hydration in a certain concentration of standard acid before and after cement hydration.
The difference between the two is used to determine the cement hydration heat of cement at any age.
Dual test units provide higher efficiency, each test unit can be operated independently.
