Abstract:

The hydration of cementitious materials results in exothermic chemical reactions. These reactions can be monitored by measuring the total heat liberated over time. The amount of heat liberated by cement hydration depends on the chemical and physical properties of the cementitious materials and admixtures used in the concrete mixture. The heat of early hydration reactions can be measured using a Semi-Adiabatic Calorimeter. The hydration curve generated from this process is called the Heat Signature.
