Solubilizing agents are mixed with water insoluble defoamers and a dispersant for cementitious compositions to provide an admixture for cementitious compositions that is stable over time. Suitable solubilizing agents include alkoxylated moieties or particles. A cementitious composition is provided that includes cement, water, a water insoluble defoamer, a dispersant for cementitious compositions, and a solubilizing agent that solubilizes the water insoluble defoamer. A method is provided for making a cementitious composition that includes mixing cement, water, a water insoluble defoamer, a dispersant for cementitious compositions, and a solubilizing agent that solubilizes the water insoluble defoamer.
