SOLUBILIZED DEFOAMERS FOR CEMENTITIOUS COMPOSITIONS |
摘要 |
<p>Amine solubilizing agents are mixed with water insoluble defoamers and optionally a dispersant for cementitious compositions to provide an admixture for cementitious compositions that is stable over time. A cementitious composition is provided that includes cementitious material, water, a water insoluble defoamer, optionally a dispersant for cementitious compositions, and an amine solubilizing agent that solubilizes the water insoluble defoamer. A method is provided for making a cementitious composition that includes mixing cementitious material, water, a water insoluble defoamer, an amine solubilizing agent that solubilizes the water insoluble defoamer, and optionally a dispersant for cementitious compositions.</p> |
