Abstract
The adiabatic temperature rise of concrete was numerically simulated, which was the typical exotheric phenomenon of concrete. First, the degree of cement hydration was predicted using the mathematical model for the hydration of cement and the formation of microstructure. Next, the heat of cement hydration was calculated with its degree of hydration. Finally, the concrete temperature under the adiabatic condition was predicted by simulating the heat conduction in the concrete cell modeled with an aggregate and cement paste around it. The simulation accuracy was discussed by comparing with the experimental adiabatic temperature rise of, concrete. It was found that the simulation in this study was useful for predicting the exotheric phenomenon of concrete.
