A process for preparing a hardening accelerating composition, hardening accelerating composition, use thereof and mixtures of building material containing a hardening accelerating composition.
A process for preparing a hardening accelerating composition, hardening accelerating composition, use thereof and mixtures of building material containing a hardening accelerating composition.
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.
