Description

The purpose of this paper is to propose a prediction method of adiabatic temperature rise curves of concretes with the simplified adiabatic apparatus which consists of metal frames and foam polystyrene. These testing methods are simpler than ordinary ones, so it is applicable to practical works. Parameters of an adiabatic temperature rise curve are identified so that the temperature-time curve measured at the center of specimen corresponds to that estimated by FEM. To verify the methods, a series of simplified adiabatic and water circulatory type tests with different concreting temperature 11, 21, 32°C, was conducted. The adiabatic temperature rise curves estimated by FEM were almost consistent with those measured by the water circulatory type apparatus. The differences between the estimated and measured results on the final temperature rise of concretes were within 1.5°C.
