Beschreibung
Zusammenfassung:	The invention concerns a solid composition comprising calcium silicate hydrate and at least one water-soluble cationic (co)polymer. Additionally, a process for producing the compositions, in which an aqueous suspension of calcium silicate hydrate, preferably suitable as a setting and curing accelerator for (portland)cement-containing binder systems, is contacted with at least one cationic (co)polymer and the product is dried. Also concerned is the use as setting accelerator in preferably (portland)cement-containing building material mixtures and as grinding assistant in the production of (portland) cement. The invention further concerned building material mixtures comprising the solid compositions of the invention.
