Title (EN) RETARDER FOR CALCIUM SULFOALUMINATE BELITE CEMENT
(FR) RETARDATEUR POUR CIMENT DE TYPE SULFOALUMINATE DE CALCIUM-BÉLITE
Abstract:
(EN) The invention relates to using a combination of an aminopolycarboxylic acid or salt thererof with a carboxylic acid having only carbon, hydrogen, and oxygen atoms in its molecule or salt thererof as retarder for calcium sulfoaluminate belite cements; by a method of retarding the setting of calcium sulfoaluminate belite binder by adding a combination of an aminopolycarboxylic acid or salt thererof with a carboxylic acid having only carbon, hydrogen, and oxygen atoms in its molecule or salt thererof to the cement and to a calcium sulfoaluminate belite binder with controlled setting comprising at least 70 % by weight calcium sulfoaluminate belite cement obtained from a calcium sulfoaluminate belite clinker containing at least 20 wt.-% by weight belite and a combination of at least one aminopolycarboxylic acid or salt thererof with at least one of a carboxylic acid having only carbon, hydrogen, and oxygen atoms in its molecule or salt thererof.
(FR) L'invention concerne l'utilisation d'une combinaison d'un acide aminopolycarboxylique ou d'un sel correspondant avec un acide carboxylique comprenant uniquement des atomes de carbone, d'hydrogène et d'oxygène dans sa molécule ou un sel correspondant en tant que retardateur pour des ciments de type sulfoaluminate de calcium-bélite; un procédé de retardement de la prise d'un liant de type sulfoaluminate de calcium-bélite par addition d'une combinaison d'un acide aminopolycarboxylique ou d'un sel correspondant avec un acide carboxylique comprenant uniquement des atomes de carbone, d'hydrogène et d'oxygène dans sa molécule ou un sel correspondant au ciment; et un liant de type sulfoaluminate de calcium-bélite à prise contrôlée comprenant au moins 70 % en poids de ciment de type sulfoaluminate de calcium-bélite obtenu à partir d'un clinker de type sulfoaluminate de calcium-bélite contenant au moins 20 % en poids de bélite et une combinaison d'au moins un acide aminopolycarboxylique ou d'un sel correspondant avec au moins un acide carboxylique comprenant uniquement des atomes de carbone, d'hydrogène et d'oxygène dans sa molécule ou son sel.
