Method for producing granulated materials from cement compositions
The invention relates to a method for producing aggregates from non-hardened cement compositions, in particular from concrete or residual concrete, which method comprises adding a) a water-absorbing agent and b) a crystallization deactivator to a non-hardened cement composition and mixing until a granular material has formed. The method allows unneeded residues of still liquid concrete to be converted into a practical product, which can then be reused to produce new concrete compositions. The invention further relates to a granulated cement material that can be obtained according to a corresponding method, to the use of said granulated cement material as an additive for cement compositions, and to additive combinations for cement compositions, which additive combinations comprise a water-absorbing agent and a crystallization activator.
