Defoamer for water reducer admixture |
| abstract |
An exemplary admixture system for cementitious compositions, comprises a polycarboxylic acid type water reducer and a tertiary amine defoamer having an average molecular weight of 100-1500 and more preferably 200-750. The defoamer permits a stable admixture formulation and helps to achieve a controllable level of entrained air in a concrete mix. Cementitious compositions and methods for modifying the same, using the tertiary amine defoamers, are also described herein. |
