A multichambered microcalorimeter for the investigation of cement hydration

Abstract A heat-conduction or Tian type isothermal microcalorimeter to measure the rate of heat liberation during the hydration of cement has been designed and constructed. The calorimeter is of high sensitivity allowing measurements to be performed on samples as small as 0.1 g. The calorimeter is equipped with an internal heater which allows isothermal calorimetric determinations to be made at various, constant temperatures. Mixing of the reactants occurs within the calorimetric cell which allows the study of early hydration reactions.
