that's not the same stuff... the crystal type formation and the powdery substance in the original poster's pics are efflorescence ... it comes out of cementous material just like the pics are showing.. note how it emerges from the edges of the wet area and as the water dries the crystals form. It can, and often does, form in areas that have never shown it before after an area has been wet for a long time.. long periods of rain etc..
your pics are much different.. I don't have a clue what that is.. I suppose it could be some kind of chemtrail residue..
