Most deicing chemicals enhance freeze-thaw cycling (which can cause spalling). You should avoid applying deicers on new concrete during the first winter because concrete that is less than a year old is less resistant to freezing and thawing than older concrete. Ice melts harm concrete if used excessively. It can also make surfaces slippery.
