Beschreibung
Zusammenfassung:	An aqueous admixture composition having a water-reducing agent, a water-soluble polymer composition, and water which is suitable for extending the time of effective fluidity of concrete mixtures is described. Also the process for preparing concrete mixtures having a cementitious binding agent, aggregate compositions, water-reducing agent and water is improved by incorporating a water-soluble polymer composition in the solids mixture of the binding agent and aggregate compositions. Concrete mixtures prepared thereby also exhibit extended time of fluidity compared to concrete mixtures prepared without the incorporation of the water-soluble polymer composition.
