CA 2522347
Cement wallboards and methods for their preparation are disclosed. The wallboards comprise two scrim layers and one mat layer. The wallboards have a smooth surface, are strong, lightweight, and easy to score and snap. Tiles can be readily adhered to the boards. The wallboards can be used in general commercial and residential construction, and are particularly attractive for use in high water/moisture areas such as bathrooms and shower enclosures.
L'invention concerne des plaques de ciment mixtes et des procédés permettant de les préparer. Ces plaques mixtes comprennent deux couches de canevas et une couche formé d'un mat. Elles possèdent une surface lisse, et sont résistantes, légères et faciles à entailler et à diviser. Ces plaques se prêtent bien à l'application de carreaux. Elles peuvent être utilisées dans les constructions commerciales et résidentielles, et sont particulièrement indiquées dans des zones présentant un taux élevé d'eau/humidité telles que salles de bains et cabines de douche.
