PURPOSE:To provide a cement mortar composition wherein liquid sagging on the surface is not caused while intactly holding excellent adhesive property, strength and workability retained by conventional cement mortar composition and a tile does not slide down in a state of undried mortar even when the tile is mounted thereon. CONSTITUTION:Cement mortar composition is obtained by adding 0.02-3 pts.wt. water soluble cellulose ether and 0.001-2.0 pts.wt. alkali metallic salt of sulfoethyl cellulose wherein the degree of substitution of a sulfoethyl group is 0.1-2.5 and viscosity of 2% aqueous solution is 10cPs or more to 100 pts.wt. cement. |
