Title (EN) NANOCELLULOSE FOAM STABILIZING ADDITIVE
(FR) ADDITIF STABILISANT À BASE DE MOUSSE DE NANOCELLULOSE
Abstract:
(EN) A variety of systems, methods and compositions are disclosed, including, in one method, providing a foamed cement composition comprising a hydraulic cement, water, a foaming surfactant, a gas, and a nanocellulose foam stabilizing additive; placing the foamed cement composition in a selected location; and allowing the foamed cement composition to set.
(FR) La présente invention concerne une variété de systèmes, de procédés et de compositions, consistant, dans un mode de réalisation, à fournir une composition de ciment cellulaire comprenant un ciment hydraulique, de l'eau, un tensioactif moussant, un gaz, et un additif de stabilisation à base de mousse de nanocellulose ; placer la composition de ciment cellulaire dans un certain emplacement ; et laisser la composition de ciment cellulaire durcir.
