Abstract (en)

[origin: WO2011064058A1] Plasticizers proposed for calcium-sulphate-containing building material mixtures in the form of flow screeds and speckling compounds are dispersing compositions which comprise a copolymer in the form of a polycarboxylate ether, said copolymer being free of dicarboxylic acids as comonomer components. Dispersants can be used in an amount of 0.002 to 1.0% by weight and in this way impart to the end products a distinct improvement in early strength, it being possible to achieve layer thicknesses of up to 10 cm in the flooring sector.
