  • Calcium Chloride product applications

    Calcium Chloride is the best choice for road stabilization, de-icing, anti-icing and dust control.
    Calcium Chloride products are safe and friendly to the environment year round:

    • safe to use and not a restricted material in transport
    • significantly less toxic than magnesium chloride
    • Calcium Chloride is a common food ingredient found in beer, cheese, canned tomatoes, olives, cherries and pickles
    • less toxic to aquatic life than oil, lignosulfonate and dish soap
    • does not bioaccumulate or have the potential to contaminate the food chain
    • may be 80-90% less corrosive than road salt
    • penetrates the road surface quickly and doesn’t leave an oily or powdery residue after its use
    • minimal impact on water, air, plants and wildlife
    • has a negligible effect on concrete

    Calcium Chloride for winter use:

    • cost effective
    • less corrosive than the millions of tones of salt applied to roadways during winter to control ice
    • aggressively attracts water from the air and soil until an equilibrium is reached with the atmosphere
    • enhances the performance of salt or sand, reducing overall cost
    • freeze-proofing sand, pre-wetting sand or salt or even directly applied as a liquid de-icer
    • unpalatable to wildlife –bitter taste detracts wildlife from road for increased road safety

    Calcium Chloride for summer use:

    • cost effective
    • reduces airborne dust that settles in adjacent bodies of water reducing impact on aquatic plants and animals
    • penetrates and stabilizes road surface
    • retains moisture by resisting evaporation, keeping the road aggregate slightly moist, and thereby improving the density of the roadway
    • reduces the cost of road maintenance, less grading frequency and aggregate replacement
    • treated roadways may be bladed without loss of performance

    Corrosion Inhibited Calcium Chloride*

    Liquid Calcium Chloride is hard on ice but easy on corrosion.
    The growing need for corrosion-inhibited deicers has prompted manufacturers to explore their production. One example of this is a new corrosion-inhibited grade of liquid calcium chloride introduced by General Chemical Corp. designed to meet or exceed Idaho’s and Washington’s deicer standards in all respects. In addition to providing low corrosion versus salt, it has calcium chloride’s operational benefits in that it continues to melt snow and ice below 20 deg F, the temperature at which salt becomes an inefficient deicer.
    The Idaho DOT began using corrosion-inhibited calcium chloride in January 1996 for deicing and anti-icing. Those using the material in Idaho report that it aggressively melts snow and ice, and that it offers operational benefits versus magnesium chloride, which has been the primary deicer used in that state due to local availability.

    Evaluations show that 25%, 30% and 32% aqueous solutions of the inhibited liquid calcium chloride produce just 4 to 7 mils/year of corrosion or 80% to 90% less corrosion than sodium chloride. Testing was done by Control Services, Kerville, Texas, a leading independent corrosion testing laboratory, using the NACE methods in the Washington specification. The tests compared sodium chloride, regular and corrosion-inhibited calcium chloride, and water. Water is taken as the baseline, so its effects were subtracted from the corrosion values of the other materials.

    Other advantages of the new corrosion-inhibited calcium chloride are its ability to cut through snow and ice more quickly than salt or magnesium chloride, lack of sediment problems in tanks and easy clean-up of vehicles.
