Experimental research on frost resistance of concrete under the action of de-icing salt

The de-icing salt is widely utilized in Northeast China for its removal of snow and ice. However, the remain of frozen salt from the de-icing salt on concrete roads can lead to erosion. In this paper, frost resistance of concrete under the action of the de-icing salt analysis was carried out, in which concrete freeze-thaw under the action of different types of de-icing salt were researched, and de-icing salt on the different strength concrete function of freeze-thaw were also researched. The analysis of the test data will show that the de-icing salt on concrete´s mechanism of action is the same, environmental protection type de-icing salt on surface corrosion is relatively small; corrosion of the de-icing salt on concrete is related with its strength, the strengther the salt content is, the smaller corrosion it is. It will have a guiding significancebe on road design in Northeast China and frost resistance of concrete under the action of de-icing salt analysis.
