Beschreibung
Zusammenfassung:An aqueous oil-in-water emulsion containing a propylethoxysilane oligomer mixture or a mixture of a propylethoxysilane oligomer mixture and octyltriethoxysilane in a weight ratio of 3:1 to 1:3, at least one emulsifier or an emulsifier system, at least one content of a 2-aminoethanol and water is used as an addition in the production of hydraulically setting cement mixtures such as mortar, screed or concrete for reduction of the shrinkage characteristics.
