(ES) USO DE CARBOXIMETILQUITOSANOS COMO ADITIVOS EN COMPOSICIONES CONGLOMERANTES
(FR) UTILISATION DE CARBOXYMÉTHYLCHITOSANES EN TANT QU'ADDITIFS DANS DES COMPOSITIONS AGGLOMÉRANTES
Abstract: front page image
(EN)The invention relates to the field of agglomerating compositions for construction and, more specifically, to the use of carboxymethyl chitosan as a flocculation additive and setting accelerator in agglomerating compositions of the cement, cement mortar, concrete, grout, stucco or similar type. The invention also relates to agglomerating compositions comprising carboxymethyl chitosan and to the preparation method thereof.
(ES)La presente invención pertenece al campo de las composiciones conglomerantes para construcción, más concretamente se refiere al uso de carboximetilquitosano como aditivo floculante y acelerador del fraguado en composiciones conglomerantes del tipo cemento, mortero de cemento, hormigón, lechada, estuco y similares. La invención también se refiere a composiciones conglomerantes que comprenden carboximetilquitosano, así como al método para su preparación
(FR)La présente invention concerne le domaine des compositions agglomérantes destinées à la construction, plus spécifiquement à l'utilisation de carboxyméthylchitosane comme additif floculant et accélérateur de la prise dans des compositions agglomérantes de type ciment, mortier de ciment, béton, coulis de ciment, stuc et similaire. L'invention concerne également des compositions agglomérantes qui contiennent du carboxyméthylchitosane, ainsi que le procédé de préparation associé.
