Self-heating and deicing conductive cement. Experimental study and modeling
Highlights Heating of different cement matrix added with carbon materials was achieved. Different heating curves shape depends on temperature reached and moisture content. The proposed model predicts the behavior of samples when heating below 60°C. A feasible method is shown to prevent ice layers in transportation infrastructures.
Abstract This research studies the self-heating produced by the application of an electric current to conductive cement pastes with carbonaceous materials. The main parameters studied were: type and percentage of carbonaceous materials, effect of moisture, electrical resistance, power consumption, maximum temperature reached and its evolution and ice melting kinetics are the main parameters studied. A mathematical model is also proposed, which predicts that the degree of heating is adjustable with the applied voltage. Finally, the results have been applied to ensure that cementitious materials studied are feasible to control ice layers in transportation infrastructures.
