Graphite-cement slurry infiltrated fiber concrete(GSIFCON) specimens were used in the temperature rising and deicing tests under different environmental temperature.The test results indicate that GSIFCON has good electrothermal properties.If a 3 cm thickness insulating layer is placed at the side and in the bottom of the specimens,the temperature rising speed of the specimens increases by over 40%.Under different negative temperature environment,the power has a little influence on the deicing efficiency and...
