Abstract
Semi-adiabatic devices are widely used as a substitute for the adiabatic calorimeter to predict adiabatic temperature rise. The maximum temperature and the reaction rate in the adiabatic temperature rise are important parameters to demonstrate the thermal characteristic and mechanical properties of concrete. However, the existing method for the prediction of the adiabatic temperature rise from semi-adiabatic device only includes heat loss compensation, which is related to the maximum temperature, though the reaction rate is even more important. Therefore, a new compensation method regarding the reaction rate is suggested in this paper. It improves the accuracy of prediction of adiabatic temperature rise.
