However, determining what deicing chemical will work best for a specific customer takes a more sophisticated eye.
Magnesium chloride is a natural salt pumped from the Great Salt Lake and concentrated in holding ponds. In a 25 to 30% concentration, the liquid prevents ice from bonding to a road. Dr. Bill Lewis said that one aspect mitigating magnesium chloride's application is the possibility of . But magnesium chloride dissolves when there is only about 20 to 30 percent humidity. “Which means that your vehicle, if magnesium chloride is sprayed on it, is wet constantly,” Baboian said. Magnesium chloride often said to be “safe on concrete”. However, there is plenty of research evidence showing magnesium chloride (MgCl2) is harmful to concrete as referenced below: Magnesium Chloride as a Road Deicer: A Critical Review.
Benefits include reduced flooding and ponding, stormwater quality improvements, etc. Some deicing salts can have negative impacts on the pervious concrete layer.
The objectives of these studies are the initial development of simple testing methods that others can use to compare various mix designs or treatments to pervious concrete to determine which options might be more resistant to deicer deterioration.
Influent and effluent samples were collected. The specimens in the laboratory receiving the calcium chloride had noticeable debris breaking from the columns, indicating that a simple protocol without extensive chemical or physical testing might be appropriate for calcium chloride comparison testing.
The specimens in the cold room that received the magnesium chloride treatment appear to have increased calcium concentrations in the effluent. Further testing on the mechanical properties for these specimens are planned to see if this possible ion exchange reaction may be a cause for degradation.
Preliminary work was performed at Washington State University and additional research is ongoing at the Lamar University campus in Beaumont, Texas.But magnesium chloride dissolves when there is only about 20 to 30 percent humidity.
“Which means that your vehicle, if magnesium chloride is sprayed on it, is wet constantly,” Baboian said. Magnesium chloride is the name for the chemical compound with the formula MgCl 2 and its various hydrates MgCl 2 (H 2 O) x. These salts are typical ionic halides, being highly soluble in water.
The hydrated magnesium chloride can be extracted from brine or sea water.
Primer on the Use of Magnesium Chloride as an Ice Prevention Tool. Magnesium Chloride (or Mag as we call it) has been commonly used as a de-icing and anti-icing agent for .
De-Icer with MCi3 & CMA This % natural eco-friendly formulation makes meltco™ Premium a very safe and effective de-icer. meltco™ Premium De . •Calcium and Magnesium Chloride Solid Deicers down to ~ 0F •Solid calcium chloride melts more ice than solid magnesium chloride (mag chloride flake is ~ 53% water) •Liquid mag chloride melts slightly more than liquid calcium chloride 6.
Solids vs. Liquids. • Magnesium chloride: Like calcium chloride, magnesium chloride is a more effective de-icer than salt, working at temperatures as low as degrees Fahrenheit. Because it’s also less harmful to plants, animals, soil and water, it similarly poses less of an environmental threat and doesn’t require post-application cleanup.
