Is magnesium chloride ice melt safe for concrete?
Accordingly, is magnesium chloride safe on concrete?
The use of Magnesium Chloride, also sometimes referred to as MAG, as an ice melter to melt the ice on concrete sidewalks, driveways or roads can be deadly. While deicing salts containing sodium, potassium and calcium are chemically innocuous to concrete, this is not true of magnesium.
Also Know, is sodium chloride ice melt safe for concrete? Rock salt or sodium chloride is the most commonly used ice melter. It is inexpensive and melts ice. Compared to other materials, though, it has limited effectiveness in very cold temperatures. It will not melt ice at temperatures below 20o F, and it may be harmful to vegetation, but is considered safe for concrete.
Correspondingly, which ice melt is safe for concrete?
Good ice melt choices for concrete are Calcium Chloride and Magnesium Chloride. While Potassium Chloride is good for the environment it damages the concrete and typically costs 3-5 times more.
Is ice melt harmful to concrete?
There has been concern that de-icers can damage the concrete due to the chemicals that melt the ice. Most de-icers for concrete are chloride combinations, usually sodium (rock salt) or magnesium. Sodium Chloride is rock salt, and it can cause damage to plants and metals – it's salt.
