Mixtures of hydrogel-forming polymers and building materials

Abstract

Mixtures of finely divided solid hydrogel-forming polymers and of hydraulically setting building materials, wherein not more than 2% by weight of said finely divided hydrogel-forming polymers are more than 200 μm in particle size. The finely divided solid hydrogel-forming polymers used are in particular crosslinked polymers having acid groups.
