ADDITIV FÜR HYDRAULISCH ABBINDENDE MASSEN
Additive comprises an aqueous, colloidally disperse preparation of at least one salt of a polyvalent metal cation and of at least one polymeric dispersant, which comprises anionic and/or anionogenic groups and polyether side chains. The metal cation comprises aluminum (Al 3> +>), iron (Fe 3> +>, Fe 2> +>), zinc (Zn 2> +>), manganese (Mn 2> +>), copper (Cu 2> +>), magnesium (Mg 2> +>), calcium (Ca 2> +>), strontium (Sr 2> +>) and barium (Ba 2> +>), is present in an amount such that a relation as given in the specification of 1-30. An independent claim is included for preparing the additive for hydraulically setting compositions, comprising precipitating the salt of the polyvalent metal cation in the presence of the polymeric dispersant to obtain the colloidally disperse preparation of the salt or dispersing a freshly precipitated salt of polyvalent metal cation in the presence of the polymeric dispersant to obtain the colloidally disperse preparation of the salt.
