non corrosive de-icing chemicals
(OP)
1. Has anyone any experience with non-corrosive deicing chemicals such as calcium magnesium acetate or urea? I know these will not melt ice at lower than about minus 5 degres C, but what I am interested in is whether anyone knows anyone (other than an airport on their runways) that is actually using these chemocals?
2. Does anyone have expreince with or know where a less corrosive de-icing chemical than clacium chloride or sodium chloride is being used in Canada or parts of the U.S. with similar climates?

Plain old salt (NaCl) is a good choice, as long as there is good quality concrete protecting any steel. Properly placed epoxy-coated reinforcement will last indefinitely (all steel must be coated, and coated tie wire and bar supports must be used.) Mag chloride provides twice as much chloride ion (the damaging part for steel) so it is a poor choice, unless you can apply half as much and get the same control.
For steel structures, where concrete durability is not an issue, the acetates may work well.
