Hydration heat of concrete is closely related to thermal stress and crack, and the adiabatic temperature rise test is a typical testing method for measuring hydration heat. The aim of this study is to investigate the effect of cement content and placing temperature on adiabatic temperature rise of concrete. To investigate the behavior of adiabatic temperature rise of concrete, it was decided to set binder content taking into account the mixing temperature of concrete and the placing temperature of concrete that are 25ºC and 35ºC, respectively. Cement content has a linear relation with the maximum value of adiabatic temperature rise (K) and reaction factor (r). The temperature rising ratio of the specimen with placing temperature 35ºC rapidly increased compared to that of the specimen with placing temperature 25ºC, but the maximum value of adiabatic temperature rise between placing temperatures 25ºC and 35ºC are not significantly different. Furthermore, it is found that the starting time of hydration heat (t0) after the placement of concrete has a high correlation with the final setting time. It is necessary to analyze the effect of adiabatic temperature rise by taking the final setting time into consideration. |
