The invention relates to dispersingly acting compositions as flow agents in the form of flowing screeds and putties for building material mixtures containing calcium sulfates, wherein said compositions comprise a copolymer in the form of a polycarboxylate ether and wherein the copolymer is free of dicarbolic acids as comonomer components. Dispersing agents can be used in an amount ranging from 0.002 to 1.0% by weight and thus provide the end products with a significantly improved early strength, wherein layer thicknesses of up to 10 cm can be achieved in the flooring area. |
