Title:
コンクリートの発熱特性試験装置及び発熱特性試験方法
Document Type and Number:
Japanese Patent JP7300982
Kind Code:
B2
Abstract:
To evaluate heating characteristics of concrete on a safe side.SOLUTION: A heating characteristic test device 1 for concrete includes: a thermal insulating container 3 having an internal space 31 for installing a filling container 5 filled with concrete; a sheet heater 4 arranged in a circumferential and planar shape between a side wall of the thermal insulating container 3 and an installation area of the filling container 5; control means for controlling the sheet heater 4; a first thermometer arranged inside the filling container 5; and a second thermometer arranged between the filling container 5 and the sheet heater 4. The control means determines a temperature difference T2-T1 between the temperature T1 measured by a first thermometer and the temperature T2 measured by a second thermometer, and controls the sheet heater 4 so that the temperature difference becomes positive.SELECTED DRAWING: Figure 1
