The evaluating test for adiabatic temperature rise in concrete is not adequate for daily quality control because it requires considerable labor. In order to establish a convenient method for the evaluation of adiabatic temperature rise using about 30mL of mortar sample only, we produced an adiabatic calorimeter experimentally. In this paper, the accuracy and the applicability of this equipment is investigated. Values of adiabatic temperature rise measured using this equipment were found to correspond to those obtained using existing equipment, by the correction of heat capacity of a sample container. Clear differences were observed between mortar samples with different blending conditions. These results suggest that the quality control of cement and preparatory experiments could be practiced reasonably by using this adiabatic calorimeter.
