(FR) FORMULATIONS DE BÉTON ET ADJUVANTS S'Y RAPPORTANT
Abstract: front page image
(EN)A chemical formulation including: (a) at least one cement dispersant selected to disperse cementitious particles disposed in a water-based, flowable cementitious mixture, the cement dispersant including a polyphosphate; (b) a surfactant selected to reduce a surface tension of the mixture; (c) an accelerator selected to accelerate setting of the mixture; the formulation containing at least 200 grams of the polyphosphate per mole of an oxyalkalene functional group within the formulation.
(FR)L'invention porte sur une formulation chimique comprenant : (a) au moins un dispersant de ciment choisi pour disperser des particules cimentaires disposées dans un mélange cimentaire coulant à base d'eau, le dispersant de ciment comprenant un polyphosphate; (b) un tensioactif choisi pour réduire une tension superficielle du mélange; et (c) un accélérateur choisi pour accélérer la prise du mélange; la formulation contenant au moins 200 grammes du polyphosphate par mole d'un groupe fonctionnel oxyalkylène présent dans la formulation.
