Heat of Hydration for Cement: Statistical Modeling

Heat of hydration is currently measured in one of two ways: acid dissolution of the raw cement and a hydrated cement after 7 days or isothermal calorimetry. In principle, the heat of hydration should be predictable from knowledge of the cement composition and perhaps some measure of the cement fineness or total surface area.

The Cement Manufacturing Process

In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.
