Abstract

The evaluating test for adiabatic temperature rise in concrete is not adequate for daily quality test because it requires considerable labor. In this report, we investigated the applicability and the adequate conditions for quality prediction of concrete using an adiabatic calorimeter used for small mortar sample. By using this equipment, clear differences were observed between mortar samples. Curves of adiabatic temperature rise of mortar were found to become similar to those obtained in concrete, by setting a mix proportion of mortar based on the heat balance. These results suggest that quality test of cement could be practiced reasonably by using this method.
