Abstract
Chemical formulations containing calcium oxide, or unslaked calcined limestone, and a chemical deicing agent. The formulations liberate heat upon contacting ice or snow and materially assist the normal deicing function. Deicer options include calcium acetate, sodium acetate, magnesium acetate, and potassium acetate and sodium chloride (salt). The magnesium acetate containing formulation represents a special case in which the ultimate products formed are magnesium hydroxide and calcium acetate, both relatively harmless to the environment.
