The commercial aircraft deicing fluid has some destruction to the ordinary pavement cement concrete.But it is unknown that the destruction is coming forming freeze thawing or chemical corrosion.Immersed Ordinary Portland cement concrete(OPC) into concentrated (25%) commercial aircraft deicer (LBR-A deicing fluid) to conduct corrosion immersion experiment over a period of 1522 days and freeze-thawed experiment for 200 cycles.The paper examineed the effects, in terms of the denudation of the unit surface area ,the relative dynamic modulus of the unit surface area, the surface visual deterioration.The corrosion resistance and freezing resistance in 25% CMA were compared.The results showed that:high concentration of commercial deicing fluid (LBR-A) has freeze-thaw damage and corrosion damage to the OPC.OPCs freeze-thawed damage is mainly caused by the internal micro cracks extended and the decline of the relative dynamic modulus.The surface denudation is not the cause.A high concentration of LBR-A solution (25%)can change the internal structure of OPC and can generate internal crack in the Corrosion immersion experiment.Its corrosion damage mainly embodies in the corner of cement mortars peeling off.The results also show that using 450g/m2 as the denudation stand is more reasonable than 1500g/m2.
