During the corrosion cycle of 50 day, for the surface of OPC in the aircraft deicer it has net cracks, while in the airport pavement deicer it doesn’t show a tendency to crack but having white matter. Under the coupling effect of corrosion and freeze-thaw, the surface properties of the aircraft deicer are better than that of the airport pavement deicer. Under the simple corrosion cycle or coupling action of corrosion and freeze-thaw for the deterioration degree of mechanical properties (compressive strength and flexural strength) of airport pavement concrete the airport pavement deicer is larger than the aircraft deicer. Finally, no matter whether the aircraft deicer or airfield pavement deicer, the coupling effect of corrosion and freeze-thaw has a significant influence on the concrete degradation of the airport deicing plateau.
