Title (EN) BINDER COMPOSITION AND MORTAR COMPOSITION, ESPECIALLY SELF-LEVELLING MORTAR COMPOSITION, HAVING IMPROVED POLISHING RESISTANCE
(FR) COMPOSITION DE LIANT ET COMPOSITION DE MORTIER, EN PARTICULIER COMPOSITION DE MORTIER AUTONIVELANT, PRÉSENTANT UNE MEILLEURE RÉSISTANCE AU POLISSAGE
Abstract:
(EN) The invention relates to a binder composition comprising at least (a) one calcium aluminate cement, said calcium aluminate cement comprising by weight relative to its total weight, - as regards its chemical composition at least : 50% or less of AI2O3 and, - as regards its mineralogical composition at least: 50% or more of CA phase, preferably from 50 % to 70 % of CA, and 0.8 % to 15 % of CA2; said calcium aluminate cement comprising a Blaine Specific Area (BSA) higher than or equal to 3800 cm2/g, and, said calcium aluminate cement being obtained by sintering. The invention also relates to a mortar composition, especially a self-levelling and/or self-smoothing mortar comprising the above mentioned binder composition and having improved polishing resistance.
(FR) L'invention concerne une composition de liant comprenant au moins (a) un ciment d'aluminate de calcium, ledit ciment d'aluminate de calcium comprenant en poids par rapport à son poids total, en ce qui concerne sa composition chimique, au moins : 50 % ou moins de AI2O3 et, en ce qui concerne sa composition minéralogique, au moins : 50 % ou plus de phase CA, de préférence de 50 % à 70 % de CA, et de 0,8 % à 15 % de CA2 ; ledit ciment d'aluminate de calcium comprenant une surface spécifique de Blaine (BSA) supérieure ou égale à 3 800 cm2/g, et, ledit ciment d'aluminate de calcium étant obtenu par frittage. L'invention concerne également une composition de mortier, en particulier un mortier autonivelant et/ou autolissant comprenant la composition de liant mentionnée ci-dessus et présentant une meilleure résistance au polissage.
