Hardening of cement is caused by some reactions described by the process of liberation of heat. This is referred to as Heat of Hydration. In mass concreting jobs like dams where dissipation of heat is not possible, the temperature of concrete rises. On subsequent cooling, cracks develop. Hence, it is very necessary to use cement with low heat of hydration in massive structures.
