Title (EN) STABLE AND BIODEGRADABLE FOAMED CEMENT SLURRIES, ADDITIVES AND METHODS
(FR) COULIS DE CIMENT EXPANSE BIODEGRADABLE ET STABLE, ADDITIFS ET PROCEDES ASSOCIES
Abstract:
(EN) The present invention relates to stable and biodegradable foamed cement slurries, additives and methods. A foamed cement slurry of the invention comprises a hydraulic cement, sufficient water to form a slurry, sufficient gas to form a foam and a biodegradable foaming and stabilizing additive comprising a mixture of a capryl/capramido propyl betaine surfactant and a capryl/capramido propyl dimethyl amine oxide surfactant.
(FR) L'invention concerne des coulis de ciment expansés biodégradables et stables, des additifs et des procédés associés. Un coulis de ciment expansé selon l'invention comprend un ciment hydraulique, de l'eau en suffisance pour former un coulis, du gaz en suffisance pour former une mousse et un additif biodégradable d'expansion et de stabilisation comprenant un mélange d'un tensioactif capryl/capramido propyle bétaïne et d'un tensioactif d'oxyde capryl/capramido propyle diméthyle amine.
