A NEW PROCESS FOR RESTORING THE FLOWABILITY OF A PIGMENT-CONTAINING CEMENT OR CONCRETE COMPOSITION, NEW FILLER AND PIGMENT COMPOSITION, NEW FILLER AND RESTORATION FILLER COMPOSITION, NEW USE OF A FINE FILLER AS FLOWABILITY RESTORATION FILLER

Process for restoring the « performance » of a cement slurry based on white or grey cement, containing at least one flowability-degrading pigment, in which a fine filler such as a fine GCC is used to recover up to 90 to 100 % of the flowability. The process incorporates the possibility to evaluate t...

Zusammenfassung:	Process for restoring the « performance » of a cement slurry based on white or grey cement, containing at least one flowability-degrading pigment, in which a fine filler such as a fine GCC is used to recover up to 90 to 100 % of the flowability. The process incorporates the possibility to evaluate the color quality such as L, a, b, (and R xyz factors) (diagram Fig. 6), L being evaluated at about 85 days. (to Albert: the 85 days issue wasimportant to Pascal and regarded as not known) The flowability is restored by the fine GCC, alone or in combination with the filler of the base cement composition, and the fine GCC can be combined as ready-for use premixes with either the base filler or the considered pigment.
