| Abstract: | The change of resistance are discussed during 28 days conservation in this paper. The resistance obtained by AC and digital multimeter. The resistance variation with the voltage of AC power is analyzed. The 28 days compressive strength is compared between the graphite electrically conductive concrete and the graphite and steel fiber composite electrically conductive concrete.,and is analyzed through the contents of steel fiber. The effect of different AC power on temperature rise of block is studied for the graphite and steel fiber composite electrically conductive concrete. The resistance of electrically conductive concrete is changed by temperature. |
