Title

(FR) NOUVEAU PROCÉDÉ POUR RESTAURER L'APTITUDE À L'ÉCOULEMENT D'UNE COMPOSITION DE CIMENT OU DE BÉTON CONTENANT UN PIGMENT, NOUVELLE COMPOSITION DE CHARGE ET DE PIGMENT, NOUVELLE COMPOSITION DE CHARGE ET DE CHARGE DE RESTAURATION, NOUVELLE UTILISATION D'UNE CHARGE FINE COMME CHARGE DE RESTAURATION DE L'APTITUDE À L'ÉCOULEMENT
Abstract
(EN)
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. 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.
(FR)
L'invention concerne un procédé pour restaurer les «performances » d'un coulis de ciment à base de ciment blanc ou gris contenant au moins un pigment dégradant l'aptitude à l'écoulement, dans lequel une charge fine telle qu'un GCC (carbonate de calcium broyé) fin est utilisé pour récupérer jusqu'à 90 à 100 % de l'aptitude à l'écoulement. Le procédé comprend la possibilité d'évaluer la qualité de la couleur, telle que les facteurs L, a, b (et R xyz) (schéma Fig. 6), L étant évalué à environ 85 jours. L'aptitude à l'écoulement est restaurée par le GCC fin, seul ou en combinaison avec la charge de la composition de ciment de base et le GCC fin peut être combiné en tant que prémélanges prêts à l'emploi, soit avec la charge de base, soit avec le pigment en question.
