Graphite slurry infiltrated fiber concrete(GSIFCON) slabs were manufactured successfully by infiltration technology.The electrothermal properties and snow melting tests in field of the slabs were carried out.The experimental ruslts indicate that the thermal energy produced by GSIFCON slab makes snow melt effectively.The electrothermal efficiency for melting snow of the slab with 3 cm thin polyethylene insulating layer can reach above 20%,nearly 5% more than that of the slab without the insulating layer.The ...
