Sažetak
This contribution describes a laboratory made differential calorimeter, designed to enable scientific research into the process of cement hydration. The calorimeter was calibrated electrically by means of dissipated Joule’s heat and further validated by inputting a known heat by means of warm water. Transient heat transfer processes in the calorimeter was modeled by employing lumped system analysis. The estimation of calorimeter parameters: heat loss constant, cooling constant, heat capacity and voltage to temperature conversion constant for the thermopile, is described. Heat of hydration of calcium aluminate cement paste was investigated.
