Abstract

The invention relates to an agglomerate containing at least one of the following water-soluble or water-dispersible materials as a bonding base polymer: carboxylized and/or alkoxylized starch, cellulose ether and fully synthetic vinyl polymers and/or polyacrylates. The agglomerate is characterized in that it contains a blasting agent which produces a high swelling pressure, but, advantageously, does not gel. The agglomerate can have a regular geometric form or not. Its weight should be between 0.5 and 500 g. The agglomerate is used in particular in the production of lump-free paste.
