Aqueous admixture for inorganic binder composition

Abstract

Aqueous admixtures for inorganic binder compositions, useful in the field of additive manufacturing including a) 12-55, preferably 15-50 weight-%, especially 20-45 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, and c) optionally 1-10 weight-%, preferably 2-5 weight-% of at least one retarder, based on 100 weight-% of the aqueous composition.
