Abstract RU 2648382 C2

FIELD: chemistry.

SUBSTANCE: invention relates to an additive that can be used as a curing accelerator for hydraulically set masses: a) at least one polymeric dispersant, which comprises structural units having anionic or anionogenic groups, and structural units having polyether side chains, b) at least one sulfonic acid compound of formula

(I),

wherein A1 stands for NH2, NHMe, NMe2, N(CH2-CH2-OH)2, CH3, C2H5, CH2-CH2-OH, phenyl, or p-CH3 phenyl and Kn+ stands for an alkali metal cation or an equivalent of a cation, which is selected from Ca2+, Mg2+, Sr2+, Ba2+, Zn2+, Fe2+, Fe3+, Al3+, Mn2+ or Cu2+ and c) calcium silicate hydrate particles. Invention is developed in subclaims.

EFFECT: accelerated curing for hydraulically set masses.
