Experimental Study on the Electrothermal Effect of Concrete Reinforced with Hybrid Carbon and Steel Fiber
The electrothermal effect of the carbon fiber concrete provides a new way to eliminate the snow and ice on an airfield runway. But the electrothermal effect of concrete reinforced with hybrid carbon and steel fiber and the appropriate fiber content are still unknown. The research aims at the questions above and investigates the electrothermal effect of concrete slabs with different hybrid fiber contents. It shows that the addition of steel fiber can increase the electrothermal effect of hybrid fiber concrete when the carbon fiber content is about 0.6% ∼ 0.8% of cement by weight, which means that steel fiber can help to form conductive network. But the electrothermal effect of hybrid fiber concrete is reduced when carbon fiber content reaches 1.0% of cement by weight, because the addition of steel fiber will block uniform dispersal and effective overlap of the carbon fiber and the conductive network gets worse. Air bubbles generate inside the concrete can also increase the electrical resistivity of the hybrid fiber concrete and the electrothermal effect gets worse.
