Abstract:When the utilization volume of industrial wastes and by-products in cement plants are increased, it is necessary to control the adiabatic temperature rise of cement containing a large amount of the interstitial phase. As previously reported, we produced an adiabatic calorimeter in order to evaluate the adiabatic temperature rise using about 30 mL of mortar sample only. In this study, we investigated the influence of interstitial phase composition and ground granulated blast-furnace slag on the adiabatic temperature rise of the cement mortar using the advanced calorimeter. Changes in adiabatic temperature rise were negligible even when the amount of interstitial phase of cement was increased from 18 mass% to 21 mass%. It was confirmed that the adiabatic temperature rise of cement containing the interstitial phase of more than 21 mass% was improved by a 20 mass% replacement of blast-furnace slag.
