Thermophysical properties of limestone as a function of origin (Part 1): Specific heat capacities

The influence of the origin of limestone upon its specific heat capacity and that of the burnt lime was established. For this purpose the specific heat capacity of limestones of different origins was determined. The measurements were carried out using a differential scanning calorimeter from ambient temperature Lip to 800 degrees C. In addition, the specific heat capacity of lime was measured with the same burned limestone samples Lip to 1300 degrees C The results demonstrated that the specific heat capacity of limestone is only slightly influenced by its origin; while the specific heat capacity of the produced lime varies strongly according to its origin.
