DEFOAMERS FOR HYDRATABLE CEMENTITIOUS COMPOSITIONS
The present invention discloses additive compositions, cementitious compositions, and methods for controlling air in cementitious compositions, wherein a polyalkoxylated polyalkylene polyamine defoamer is deployed in combination with one or more air-entraining agents, such as higher alkanolamines, water-reducing agents including oxyalkylene-containing superplasticizers, or other air entraining agents.
