Abstract: The invention relates to a process for producing a composition suitable as an accelerator for the hardening of cement, wherein the components aa) at least one component selected from the group of hydraulic binders and/or latently hydraulic binders and bb) at least one dispersant suitable for the dispersion of inorganic pigments in water and cc) water are contacted with one another, where the weight ratio of components aa) to cc) is between 1.5:1 and 1:70, where the weight ratio of components aa) to bb) is between 20:1 and 1:2. Further disclosed is the use of the composition obtained as setting accelerator for mixtures in construction chemistry.

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.
