Experimental study on deicing performance of carbon fiber reinforced conductive concrete
CFRC (carbon fiber reinforced concrete) is a kind of good electrothermal material. When connected to an external power supply, stable and uniform heat suitable for deicing application is generated in the CFRC slab. Electric heating and deicing experiments of carbon fiber reinforced concrete slab were carried out in laboratory, and the effect of the temperature and thickness of ice, the thermal conductivity of CFRC, and power output on deicing performance and energy consumption were investigated. The experimental results indicate that it is an effective method to utilize the thermal energy produced by CFRC slab to deice. The time to melt the ice completely decreases with increasing power output and ice temperature, and increases with increasing thickness of the ice. The energy consumption to melt 2 mm thickness of ice varies approximately linearly from 0.556 to 0.846 kWh/m2 as the initial temperature ranges from -3 deg C to -18 deg C. CFRC with good thermal conduction can reduce temperature difference in CFRC slab effectively.
