This study examines the thermal analysis technique in concrete by quantification of heat of hydration when a low hydration heat cement is used.The adiabatic temperature rise of blast-furnace slag cement of type B (mix ratio of blast-furnace slag;55%) with 20% fly ash was measured by varying the initial temperature (20°C and 30°C), cement content (270-340kg/m3) and water-cement ratio (45-55%).It was observerd that the adiabatic temperature rise and the heat of hydration per 1kg of cement were not influenced by the initial temperature, and the cement content or the water-cement ratio.Thermal analysis was made for an actual mass concrete structure was analyzed using this hydration model.The analysis results was measured an accuracy of 1-2°C.Thus, the temperature rise of concrete can be analyzed an accuracy using generalized hydration model of cement.
