SLIPPERY, SALT ACROSS IT?

GLAD, ZOUT EROVER?

In this article a number of deicing agents used in winter maintenance are subjected to the following requirements: (a) effectiveness; (b) aspects related to use; and (c) environmental aspects. The following deicing agents are discussed: (1) sodium chloride; (2) calcium chloride; (3) magnesium chloride; (4) ethylene glycol; (5) calcium magnesium acetate (CMA); (6) sodium formate (salt from formic acid); and (7) urea. When investigating the effectiveness of deicing agents, the thaw effect, the lowering of the freezing point, the workability up to a certain temperature below zero, and the particle size distribution play a role. Aspects related to use are, that the agent may not be combustible, biting or corrosive, and that it must be easily manageable. As far as the environmental aspects are concerned, it appears that the damaging impact of the salts on the environment is very little. The conclusion is drawn that no ideal deicing agent exists. Considering all the deicing agents available, it appears that pure sodium chloride is the best alternative.
