Abstract:
The use of an adhesion-promoting additive combination composed of one or more polyalkylenoxides out of the group comprising polypropylene oxides and ethylene oxide-propylene oxide copolymers, and of one or more starch ether derivatives out of the group comprising carboxyalkyl starch ethers and their alkali salts, and hydroxyalkyl starch ethers, in mortar compositions comprising mineral binders and water-redispersible polymer powders.
