Magnesium Chloride Safe For Concrete

While potassium chloride is good for the environment it damages the concrete and typically costs 3 5 times more.

Magnesium chloride safe for concrete.

Due to the significant amount of scientific information on the concrete damaging effects of magnesium chloride and calcium chloride. Magnesium chloride is works well in temperatures as low as 5 f and is safe for concrete. During the winter of 2000 2001 it was observed that scaling of concrete surfaces increased approximately 10 times from that of the previous 9 winters in the idaho falls regional area. However magnesium chloride is slower and is not as effective in colder weather.

A critical review magnesium chloride as a road deicer. Aci 201 2r 77 in a table showing the effect of commonly used chemicals on concrete lists magnesium chloride solutions as having a slow rate of attack on concrete at. The only real benefit to using magnesium chloride over calcium chloride is that magnesium chloride is safer for vegetation. Mag was once thought to be a safe and powerful ice melting solution.

Why take the risk. Since you are handling damp salt the concrete may in effect contact a solution saturated with sodium chloride and containing magnesium chloride in some lower concentration. Good ice melt choices for concrete are calcium chloride and magnesium chloride. Salts that some people use for melting ice include sodium chloride potassium chloride calcium chloride and magnesium chloride in them.

Studies have found that ice melt formulas that combine solar salt and anti corrosion agents are less damaging to concrete and vegetation when compared to magnesium chloride and calcium chloride based ice melters. Magnesium chloride as a road deicer. Sealing your concrete can retard or delay the concrete deterioration and minimize the ugly pock marks on the concrete. This method which was designed to screen deicers quickly does not correlate to the real world because it uses substandard non air entrained concrete and only 15 freeze thaw cycles.

Snow removal 101 shines light on confusing subjects such as magnesium chloride ice melting products to basic questions such as why salt melts ice. 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. Mgcl2 suppliers claim less spalling than other deicers based on a test developed by shrp.
