A mixture composition of a cellulose ether made from raw cotton linters and at least one additive is used in a dry tile cement composition wherein the amount of the cellulose ether in the tile cement composition is significantly reduced. When this tile cement composition is mixed with water and applied to a substrate, the correction time, applicability, and sag resistance of the wet mortar are comparable or improved as compared to when using conventional similar cellulose ethers.
L'invention concerne une composition de mélange d'éther de cellulose obtenue à partir de linters de coton bruts et d'au moins un additif, utilisée dans une composition de ciment sec pour carreaux dans laquelle la quantité d'éther de cellulose de ladite composition de ciment pour carreaux est sensiblement réduite. Lorsque cette composition de ciment pour carreaux est mélangée à de l'eau et appliquée à un substrat, le temps de correction, l'applicabilité et la résistance à l'affaissement du mortier humide sont comparables ou améliorés comparés à des éthers de cellulose similaires utilisés de façon classique.
