Title (EN) DEFOAMING COMPOSITIONS
(FR) COMPOSITIONS ANTIMOUSSE
Abstract: front page image
(EN)Cement compositions and processes for reducing air entrainment in a cement composition generally include mixing a hydraulic cement with a defoamer compositions including one or more organic acid ester polymers selected from an organic acid ester of polyethylene oxide polymer, an organic acid ester of polypropylene oxide polymer, and a mixture thereof. The compositions may further comprise an organic acid ester of an ethylene oxide-propylene oxide block copolymer.
(FR)Les compositions de ciment et les procédés destinés à réduire l'entraînement d'air dans une composition de ciment comprennent généralement le mélange d'un ciment hydraulique avec une composition antimousse contenant un ou plusieurs polymères d'ester d'acide organique choisis parmi un ester d'acide organique de polymère d'oxyde de polyéthylène, un ester d'acide organique de polymère d'oxyde de polypropylène, et un mélange de ceux-ci. Les compositions peuvent en outre comprendre un ester d'acide organique d'un copolymère séquencé de type oxyde d'éthylène-oxyde de propylène.
