I would suspect that it would not be that different from OPC, whose value can easily be found in the literature. If you want an easy way to estimate its value, assuming you do not have thermoanalytical equipment (such as a Hot Disk) to make the measurement, you can easily construct a simple calorimeter using a beaker of solution of known heat capacity (an alcohol for instance, don't use water as it will react with the cement). Then, weigh the beaker empty, with the solution added (measure its temperature as well), and finally after adding the cement powder that it is first heated to an elevated (known) temperature (below the boiling point of the liquid of interest). Measuring the final temperature of the mixture in the beaker will allow a quick calculation via an energy balance (m1*deltaT1*Cp1=m2*deltaT2*Cp2) of the unknown heat capacity (neglecting any energy that is added if you stir the mixture, for example --- could further estimate this effect by performing experiment on a powder of known heat capacity...).
Dr. Bentz, in this mentioned process, how long should I wait to read the final mix temperature? Since the temperature is continuously changing until it reaches the ambient room temperature, I get different results at different time intervals. I was wondering if there is specific time to consider as final mix temp. Thanks so much Dr. D. P. Bentz .
