Can dust agglutinate without water?

  1. Dec 14, 2005 #1
    I saw a guy claiming to have studied geology and telling that "only dust of hydrated minerals could agglutinate, because agglutination is produced only by Van Der Wall forces".
    I read many times that dust can agglutinate without water traces, so I see this is wrong, but I would like to read some specialized coment or text about this matter.

    I don't even know what 'agglutinate' means. Have you tried Earth Sciences for this?

    By "agglutinate", I mean "stick together"; a thing that talc, cement and flour can do, but sand can not.

    Okay, thanks Jairo. I always thought that moisture was required for that, but I've never studied it so that's just an impression that I had.
