When the salts reach the surface they react with co2 in the air and form insoluble calcium carbonate.
Salt on concrete floor. Salt picked up on the bottom of your car during harsh winter weather can melt and eat away at the concrete. Salt does not chemically react with hardened concrete. Don t let your clients wait for a nasty springtime surprise. Make sure to use gloves and protect your hands.

Salt does however lower the freezing point of water attract moisture and increase pressure of frozen water. The calcium hydroxide present in concrete reacts with the calcium chloride in salt creating calcium oxychloride caoxy in salt thus wreaking havoc.
When moisture and water vapor migrate to the surface of hardened concrete floors walls and colored concrete it carries with it calcium hydroxide. Considered a step above smooth or broom finished concrete a salt finish leaves a speckled pattern of shallow indentations on the concrete surface similar to the appearance of slightly pitted weathered rock. A can of oven cleaner and a high pressure hose work to remove small stains but the labor.
