| Abstract: |
| Based on the experimental results, the electrothermal characteristics of graphite cement and carbon fiber graphite cement conductive composites were studied. Cement based conductive materials developed in this paper exhibit good resistance to over current and over voltage, lower surface temperature and excellent stability during heating. They are especially suitable for using as electrothermal materials. |
| Key words: cement based conductive composites,resistivity,electrothermal materials |
