Abstract: An anti-icing composition having anti-corrosion and anti-spalling properties including an anti-icing chemical selected from the group consisting of calcium chloride, sodium chloride, potassium chloride, magnesium chloride, urea, calcium magnesium acetate, calcium acetate, magnesium acetate, potassium acetate, sodium formate and combinations thereof, the anti-icing chemicals being at least 5% by weight of said anti-icing composition; an anti-corrosion compound being 2 butyne-1,4 diol in the range of trace amounts up to 5% by weight of the anti-icing composition; a water-soluble anti-spalling compound in the range of trace amounts up to 10% by weight of the anti-icing composition; and a diluent chemical, such as water, in the range of 10% to 80% by weight of said anti-icing composition.

Abstract: An alkaline, non-phosphate, ice melter composition containing common deicers and anticorrosion chemicals (used to prevent base metal attack in acid pickling baths) and which is substantially less corrosive to steel than ordinary tap water. The composition will be environmentally safer and greatly reduce the corrosion of steel bridges, parking decks, railroad station platforms, guard rails on roads, other metal structures, and the like.

Abstract: The present invention relates to ice melters having a ph of less than 7 to make them acidic and having an anti-corrosion compound dispersed therein, such as 2 Butyne-1,4 diol, so that the ice melter is environmentally safe and greatly reduces the corrosion of steel bridges, guard rails on roads, and the like.
