Abstract: The invention relates to a composition comprising 5-50 wt % of calcium silicate hydrate, 10-60 wt % of at least one water-soluble, acid group-containing polymer comprising polyether groups, and 5-40 wt % of at least one polyalkylene glycol ether. Further disclosed is a process for preparing this composition, and cementitious mixtures comprising the composition. A further aspect of the present invention is the use of the composition of the invention in cementitious mixtures for accelerating the development over time of the dispersing action of the acid group-containing polymer after addition of the mixing water and a subsequently accelerated curing of the mixture.

Abstract: A curing accelerator composition for building chemical mixtures comprises a mineral constituent and a polymeric water-soluble dispersant. The mineral constituent comprises a semi-ordered calcium silicate hydrate having an apparent crystallite size of 15 nm or less and less than 35% by weight of crystalline phases other than the semi-ordered calcium silicate hydrate. The composition displays a more pronounced accelerating effect than comparative compositions in which the mineral component comprises a calcium silicate hydrate having a higher degree of crystallinity.

Abstract: The present invention concerns an additive for construction chemical compositions, in particular mortar and cement compositions. The additive comprises at least one amide or ester of a sugar acid and at least one water-soluble comb polymer which contains, on the main chain, acid functions and side chains having ether functions. The additive is useful for retarding the hardening of a construction chemical composition.

Abstract: The invention relates to a process for the preparation of a hardening accelerator composition by reacting a calcium source selected from calcium hydroxide, calcium oxide with a water-soluble silicate compound in the presence of at least one water-soluble polymeric dispersing agent and the hardening accelerator composition obtainable by said process. The composition has a low content of anions and of alkali cations and is therefore broadly applicable in building material mixtures.
