Abstract: The invention relates to a composition comprising at least 10 wt. % of a binder based on calcium sulfate and 0.005 to 5 wt. % of an additive made of at least one water-soluble salt of a multivalent metal cation, at least one compound which is capable of releasing an anion that forms a poorly soluble salt together with the multivalent metal cation, and at least one polymer dispersant which comprises anionic and/or anionogenic groups and polyether side chains. The invention further relates to a method for producing said composition and to the use thereof as a calcium sulfate flow screed, a flowable calcium sulfate filler compound, or an earth-moist calcium sulfate screed.
