white spots on concrete driveway
white spots on concrete driveway
(OP)
Please see attached pic. The driveway has not yet been sealed. No depressions detected at white spots. The driveway was poured less than one year ago in either October or November in a Northeast climate. Even if de-icing salts were applied over the short period of time since it was first poured, would it cause this damage? Were de-icing salts possibly used too early? Could the white spots be a form of efflorescence? what are the white spots a result of?
Thanks
Thanks

thank you for your reply. I attempted to dig at the white spots, no weakness in the concrete detected from top side.

Do the spots disappear when the concrete is wet or do they stand out more? Do the white spots leave a dust on your finger when you rub it?
