Method Of Manufacturing Cementitious Compositions |
| 摘要 |
A method of manufacturing a cementitious composition comprising: dispersing expanded polymeric microspheres into a liquid dispersion, optionally wherein the liquid dispersion comprises an aqueous dispersion; and incorporating the liquid dispersion comprising expanded polymeric microspheres into the cementitious composition; wherein the expanded polymeric microspheres are present in the liquid dispersion in an amount of about 0.1 to about 15 percent by weight, based on the total weight of the dispersion, prior to incorporation into the cementitious composition. An admixture for cementitious compositions comprising unexpanded polymeric microspheres and sodium hydroxide. |

1. A method of manufacturing a cementitious composition comprising:
dispersing expanded polymeric microspheres into a liquid dispersion, optionally wherein the liquid dispersion comprises an aqueous dispersion; and incorporating the liquid dispersion comprising expanded polymeric microspheres into the cementitious composition; wherein the expanded polymeric microspheres are present in the liquid dispersion in an amount of about 0.1 to about 15 percent by weight, optionally about 0.3 to about 7.5 percent by weight, further optionally about 0.75 to about 3 percent by weight, based on the total weight of the dispersion, prior to incorporation into the cementitious composition. |
