Calcium magnesium acetate (CMA, with chemical formula C 12 H 18 CaMg 2 O 12 [1]) is a deicer and can be used as an alternative to road salt.It is approximately as corrosive as normal tap water, and in varying concentrations can be effective in stopping road ice from forming down to around −27.5 °C (−17.5 °F) (its eutectic temperature [2]).
Road salt (also known as de-icing salt, rock salt or snow salt) is a salt used mainly as an anti-slip agent in winter road conditions, but also to prevent dust and snow build-up on roads. [1] Various kinds of salts are used as road salt, but calcium chloride and sodium chloride (rock salt) are among the most common.
The first to be dispatched are gritters who do some plowing but also salt the road. The salt, via freezing point depression , helps melt the snow and ice and also gives vehicles more traction. Later, usually when the snow has ceased falling, snow plows, front end loaders with snowplow attachments, and graders cover every street pushing snow to ...

An Aeroflot Airbus A330 being de-iced at Sheremetyevo International Airport Econ Salt Spreader. De-icing is the process of removing snow, ice or frost from a surface. Anti-icing is the application of chemicals that not only de-ice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.
[38] [39] Its reaction with stomach acid produces salt, water, and carbon dioxide: NaHCO 3 + HCl → NaCl + H 2 O + CO 2 (g) A mixture of sodium bicarbonate and polyethylene glycol such as PegLyte, [ 40 ] dissolved in water and taken orally, is an effective gastrointestinal lavage preparation and laxative prior to gastrointestinal surgery ...
Other additives had been used in road salt to reduce the total costs. For example, in the US, a byproduct carbohydrate solution from sugar-beet processing was mixed with rock salt and adhered to road surfaces about 40% better than loose rock salt alone. Because it stayed on the road longer, the treatment did not have to be repeated several ...
