Ice melt works by attracting moisture, thus forming a salt-water solution known as brine. This solution generates heat, which in turn melts the ice. The following are the best ice melt products for concrete surfaces.
Experts agree that calcium chloride is the best ice melt for concrete surfaces. Being a hygroscopic compound, it absorbs moisture and thereafter, starts dissolving. The dissolving process is exothermic and generates heat of up to 60 degrees Celsius. This heat quickly melts the ice and snow, thus turning it into water.
Dissolved calcium chloride similarly works by breaking the bond that exists between concrete surfaces and ice. This compound is preferred because it is quick, less corrosive, and also poses less harm to the environment compared to other ice melts. Nonetheless, it is relatively more expensive considering that a 50-pound bag costs around $18.
This compound is routinely ranked as the best ice melt for concrete on the market. Unlike other ice melts, magnesium chloride can safely be used in heavily vegetated areas. Besides this, it is not corrosive.
