Recent efforts to reduce the burden on the environment have directed our attention toward the use of deicing chemical in preventing the corrosion of steel used for concrete, and the use of deicing chemicals for this purpose has now started. This study compares how the degree of scaling deterioration varies according to the types of deicing chemicals used. The types of deicing chemicals used were chlorides and acetates. The result of this research is as follows. While no scaling was observed on the surface for the specimens filled with pure water, scaling was found to be promoted by all of the types of deicing chemical solutions used. The degree of scaling deterioration experienced with each of the types of deicing chemicals is likely to be affected by the strain generated at the boundary between the concrete surface and the ice, dynamic modulus of elasticity and bond strength between ice and mortar.
