Aqueous blends for inorganic binder compositions
The present invention relates to aqueous blends for inorganic binder compositions such as concrete or mortar, comprising: a) 12-55, preferably 15-50, in particular 20-45% by weight of at least one anionic polymer selected from the group consisting of plasticizers, water reducing agents, superplasticizers and processability retention agents for inorganic binders, b) 15-35% by weight, preferably 20-30% by weight, of at least one water-insoluble liquid defoamer, and c) optionally 1-10% by weight, preferably 2-5% by weight, of at least one retarder, based on 100% by weight of the aqueous composition. In particular, the blends of the present invention are useful in the field of additive manufacturing.
本发明涉及用于无机粘合剂组合物例如混凝土或砂浆的水性掺合物，包含：a)12–55、优选15–50重量％、尤其20–45重量％的至少一种选自以下的阴离子聚合物：用于无机粘合剂的增塑剂、减水剂、超增塑剂和加工性保持剂，b)15–35重量％、优选20–30重量％的至少一种不溶于水的液体消泡剂，和c)任选的1–10重量％、优选2–5重量％的至少一种延迟剂，基于100重量％的水性组合物。尤其是，本发明的掺合物可用在增材制造领域。
