Salt for use of melting ice and snow works through a phenomenon called freezing-point depression, the lowering of a substances freezing point after the addition of solutes. When road salt is added to roads, aside from providing better friction for vehicles on the road, it also dissolves in the water of the ice, resulting in a lower freezing point.
Frost damage of early-age concrete is particularly harmful for the concrete mechanical resistance because the ice volume expansion causes micro-cracks in the concrete structures, and as a consequence it lowers the compressive strength of concrete. [4]
This magical homemade ice melt is easy to make, too. In a bucket, combine a half-gallon of hot water, about six drops of dish soap, and ¼ cup of rubbing alcohol.
A heated sidewalk in Holland, Michigan Installation of a geothermal snowmelt system on a street in Reykjavík, Iceland..
