Stabilized defoamers for cementitious compositions |
摘要 |
The present invention discloses additive compositions, cementitious compositions, and methods for controlling air in cementitious compositions in which colloidal nano-particles are used for stabilizing a water-dispersible defoamer within a cement-dispersant-containing aqueous additive formulation for modifying hydratable cementitious compositions such as cement or concrete. |
