Title (EN) STRENGTH ENHANCING ADMIXTURE FOR CEMENTITIOUS COMPOSITIONS
(FR) MÉLANGE AMÉLIORANT LA RÉSISTANCE POUR COMPOSITIONS CIMENTAIRES
Abstract:
(EN) A strength enhancing admixture for cementitious and/or pozzolanic compositions including, based on the total dry weight of the admixture, calcium silicate hydrate in an amount of from about 0.5 to about 94 weight percent, and: i) at least one alkanolamine in an amount of from about 0.5 to about 55 weight percent; ii) at least one inorganic accelerator in an amount of from about 0.5 to about 85 weight percent; and iii) at least one carbohydrate in an amount of from about 0.5 to about 50 weight percent; wherein the calcium silicate hydrate includes a product of a reaction of a water-soluble calcium compound with a water-soluble silicate compound in presence of a water-soluble dispersant; and wherein the at least one inorganic accelerator includes any inorganic accelerator(s) other than calcium silicate hydrate.
(FR) L'invention concerne un mélange améliorant la résistance pour des compositions cimentaires et/ou pouzzolaniques comprenant, sur la base du poids sec total du mélange, du silicate de calcium hydraté en une quantité d'environ 0,5 à environ 94 % en poids, et : i) au moins une alcanolamine en une quantité d'environ 0,5 à environ 55 % en poids ; ii) au moins un accélérateur inorganique en une quantité d'environ 0,5 à environ 85 % en poids ; et iii) au moins un hydrate de carbone en une quantité d'environ 0,5 à environ 50 % en poids ; le silicate de calcium hydraté comprenant un produit d'une réaction d'un composé de calcium soluble dans l'eau avec un composé de silicate soluble dans l'eau en présence d'un dispersant soluble dans l'eau ; et le ou les accélérateurs inorganiques comprenant tout accélérateur inorganique autre que le silicate de calcium hydraté.
