<p>Water-soluble air-controlling agents can be admixed with dispersant for cementitious compositions to provide an admixture for cementitious compositions that is stable over time. The water-soluble air-controlling agents are compatible with water based polycarboxylate polymer dispersants. Suitable water-soluble air-controlling agents include alkoxylated polymers. A cementitious composition is provided that includes cement, water, a dispersant for cementitious compositions, and a water-soluble air-controlling agent. A method is provided for making a cementitious composition that includes mixing cement, water, a dispersant for cementitious compositions, and a water-soluble air-controlling agent.</p> |
