    Abstract: A hydraulic setting adhesive containing a hydraulic binder, fillers, a water retention agent, a sulfoalkylester surfactant, and optionally a redispersible polymer powder and/or a polymer dispersion, wherein the surfactant is represented by the formula of MSO3—R1—(—COOR2)n, wherein M is selected from the group consisting of hydrogen, alkali metals, alkaline earth metals, and ammonium; R1 is linear or branched, saturated or unsaturated C1-C10 alkylene that optionally can be substituted by one or more hydroxyl, halogen, nitro or cyano groups; R2 can be identical or different from R1 and is represented by C1-C22 linear or branched alkyl; and n is an integer from 1 to 10, and wherein the hydraulic setting adhesive based on its dry weight comprises 0.1-3% by weight of the water retention agent.
