Zusammenfassung:The present invention pertains to an aqueous admixtures for inorganic binder compositions such as concrete or mortar comprisinga) 25 - 55, preferably 30 - 50 weight-%, especially 40 - 45 weight-% of at least one anionic polymer selected from the group consisiting of plasticizers, water reducers, superplasticizers and workability retainers for inorganic binders,b) 15 - 35 weight-%, preferably 20 - 30 weight-% of at least one water insoluble liquid defoamer, andc) 1 - 10 weight-%, preferably 2 - 5 weight-% of at least one retarder, based on 100 weight-% of the aqueous composition. Especially, the admixture of the present invention is useful in the field of additive manufacturing.
