Why does salt cause corrosion on hard surfaces such as concrete?
Salt lowers the freezing point of water and will allow liquid brine to fill tiny cracks in the material. Then as it becomes diluted the freezing temperature rises and the water will freeze, forcing the cracks open. Over time this will break down the surface of the material.
The Short Answer
Salt lowers the freezing point of water and will allow liquid brine to fill tiny cracks in the material. Then as it becomes diluted the freezing temperature rises and the water will freeze, forcing the cracks open. Over time this will break down the surface of the material.
