摘 要:以某电热路面工程为依托,研究了钢纤维对石墨导电混凝土电热性能的影响。对比升温实验数据发现,经过不同的冻融循环次数,钢纤维石墨导电混凝土电流均呈现三个阶段:缓慢增长阶段、快速增长阶段、稳定阶段;冻融循环使钢纤维-石墨导电混凝土的电流及其变化范围有所减小,发热功率在相同电压下有所降低。
Abstract: Based on an electric pavement project, the effect of steel fiber reinforced graphite conductive concrete on the thermal performance is studied. It is found that the current of the steel fiber graphite conductive concrete has three stages: the slow growth stage, the rapid growth stage and the stable stage, and the freeze-thaw cycle reduces the current and variation of the steel fiber graphite conductive concrete, and the heating power is reduced at the same voltage.
