CMA40 is essentially non-toxic. A series of oral, inhalation, eye, and skin tests conducted in accordance with the U. The purchase price of CMA40 is more than salt. However, studies of the life-cycle costs of salt indicate that when considering corrosion damage and environmental impact, the cost of salt often exceeds that of CMA This small amount of CMA would be ineffective in stopping corrosion.
Ask Questions: Your distributor should be able to provide the exact amount of each ingredient in the deicer blend to ensure you are receiving an adequate amount of pure CMA. Double-Check Pricing: If one price quote is much lower or higher than the others, be sure to ask the above questions to verify the same amount of CMA is being used in all products.
Customers also need to be aware that some products claim they contain CMA or calcium magnesium acetate but they actually contain a physical blend of calcium acetate and magnesium acetate. CMA is a patented formulation and each pellet contains a specific ratio of calcium and magnesium. It has undergone significant testing to show it is safe for concrete. The best corrosion protection results from the use of pure CMA In order to receive the maximum corrosion protection benefit from CMA deicer blends, it is important to verify the amount of CMA being used in the mixture.
CMA is the only commercially available pure calcium magnesium acetate produced and sold in the United States. The below examples are offered to help you determine the quantity of CMA in your deicer blend.

About This Product. Product Literature. CMA has been used successfully since by snow fighters worldwide. It is effective over a similar temperature range as road salt: performance decreases below 20 degrees F -7 degrees C.
Effectiveness is generally enhanced by traffic, sunlight, and warmer temperatures. Because CMA is acetate-based instead of chloride-based, it has unique performance characteristics. Over the years many techniques have been tested and adopted to increase its efficiency.
When mixed with snow, CMA interferes with the ability of snow particles to adhere to each other or to the surface. It does not create a flowing brine like salt, but keeps the snow lighter and drier improving traction.
Applied early in the storm, CMA prevents the formation of snow pack and the bonding of ice to the pavement surface, so snow and ice can be removed more easily by plow, broom or shovel. Because CMA does not produce a running brine, it does not move off the surface like other deicers. Therefore, fewer applications are needed during a storm and from storm to storm. Experience has shown that surfaces treated with CMA often exhibit anti-icing properties during subsequent periods of freezing moisture.
Early application is the key to effective performance of all deicers, including CMA. At the beginning of a snow event, a heavier application of CMA may be appropriate depending on local conditions. Snow plows and the action of traffic will remove the snow — leaving a residual layer of CMA. Application rates may be decreased as the storm continues. CMA exhibits very low corrosion rates on metals found in bridges, roadways, parking garages, and other steel and concrete systems. Commonly described as being about as corrosive as tap water, CMA is often used as the corrosion standard by which other deicers are judged.
FHWA, U. K Department of Transport, and other independent institutions have concluded: CMA is a proven low corrosion deicer. A switch to CMA on chloride-contaminated concrete structures may extend their useful life. Tests by the Denmark Ministry of Transport with steel rebar in chloride-contaminated concrete showed that when samples were treated with CMA solutions, corrosion rates were reduced. A number of laboratory tests suggest that CMA may be an effective corrosion inhibitor when combined with salt.
As expected, the best corrosion protection results from the use of pure CMA. Many engineers specify CMA because it does not chemically attack concrete nor does it increase spalling caused by the freeze-thaw cycling of water. Testing by Michigan DOT confirmed that CMA dramatically reduced spalling in both air-entrained and non air-entrained concrete compared to salt alone.
When sodium chloride is used as a deicer, it can result in roads becoming salt licking stations for wild animals, particularly deer. CMA has been used in deer management areas of Scandinavia to prevent road accidents.
In Finland, CMA mixed with sand at rates of pounds per ton kilograms per cubic meter kept sand from freezing. Additionally this CMA rate was sufficient to deter reindeer from roadways.
CMA has the aroma of vinegar, which does not appeal to animals. CMA is provided in bulk, 1 metric ton lb supersacks, or 25 kg 55 lb bags. CMA should be stored indoors or in weather-proof containers. Covering bulk CMA is advised in high humidity areas. When properly stored, CMA will remain effective for years. At higher concentrations some CMA may not dissolve.
CMA research conducted in a variety of academic and private laboratories indicates that negative environmental and toxicological impacts are highly unlikely from its use as a deicer.
