ADDITIV FÜR HYDRAULISCH ABBINDENDE MASSEN
Additive for hydraulically setting masses, comprises (a) at least one polymeric dispersant comprising structural units having anionic- or anionogenic groups and structural units having polyether side chains, (b) at least one sulfonic acid compound (I), and (c) calcium silicate hydrate particles. Additive for hydraulically setting masses, comprises (a) at least one polymeric dispersant comprising structural units having anionic- or anionogenic groups and structural units having polyether side chains, (b) at least one sulfonic acid compound of formula (I), and (c) calcium silicate hydrate particles. A1 : NH 2, NH-CH 3, N(CH 3) 2, N(CH 2-CH 2-OH) 2, CH 3, CH 2CH 3, CH 2-CH 2-OH, phenyl or p-CH 3-phenyl; and A2 : H, alkali metal cation or equivalent of cation, preferably Ca 2> +>, Mg 2> +>, Sr 2> +>, Ba 2> +>, Zn 2> +>, Fe 2> +>, Fe 3> +>, Al 3> +>, Mn 2> +> or Cu 2> +>. An independent claim is also included for preparing the above additive, comprising reacting at least one sulfonic acid compound of formula (III) with at least one water-soluble inorganic silicate compound in presence of an aqueous solution of the dispersant. A12 : 1/2Ca. An independent claim is also included for a building material mixture comprising the above additive and a hydraulic binder. [Image] [Image].
