(57) 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 was important to Pascal and regarded as not known). The flowability is restored by the fine GCC, alone or...
