Water Resistant Cementitious Article and Method for Preparing Same |
摘要 |
Abstract A fibrous mat-faced cementitious article comprising (a) a cementitious core, and (b) a first fibrous mat comprising polymer or mineral fibers and a hydrophobic finish on at least one surface thereof, wherein the hydrophobic finish is in contact with the cementitious core. The invention also provides a method of preparing a fibrous mat-faced cementitious article comprising (a) depositing a cementitious slurry on a first fibrous mat comprising polymer or mineral fibers and a hydrophobic finish on at least one surface thereof, wherein the cementitious slurry is deposited on the hydrophobic finish, and (b) allowing the cementitious slurry to harden, thereby providing a fibrous mat-faced cementitious article. The invention provides a method of preparing a waterresistant cementitious article comprising (a) preparing an aqueous slloxane dispersion comprising about 4 wt.% to about 8 wt.% siloxane in water, (b) combining the siloxane dispersion with a cementitious mixture to provide a cementitious slurry, (c) depositing the cementitious slurry onto a substrate, and (d) allowing the cementitious slurry to harden, thereby providing a cementitious article. |
