Isothermal Calorimetry

This lecture introduces the concept of isothermal calorimetry, a method to measure heat and heat production rate in materials like cement. It covers the principles, equipment setup, calibration, sample preparation, data interpretation, and the different stages of cement hydration. The instructor explains the importance of calorimetry measurements in understanding the physical, chemical, and biological processes related to enthalpy changes. The lecture also discusses the advantages and drawbacks of isothermal calorimetry, highlighting its repeatability, ease of testing at different temperatures, and caution required for accurate data interpretation.
