Defoaming compositions |
| abstract |
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. |
