    • The present invention relates to compositions which are suitable for optimizing mineral building material compositions so that the flow behaviour and the deaeration of the compositions is positively influenced, as a result of which very smooth, virtually pore-free surfaces can be achieved. The compositions can consist of a mixture or comprise a mixture which contains at least one component (a) which comprises a compound N which displays a wetting action in aqueous cement-containing binder systems and contains at least one further component (b) which comprises a compound E which has antifoam properties in aqueous cement-containing binder systems. The compound N in component a) can preferably be a nonionic or amphoteric surfactant, preferably an alkyl alkoxylate or a betaine. The compound E in component b) can preferably be a polyetherpolysiloxane on a support material.
    • 本发明涉及适合于优化矿物建筑材料组合物以使组合物的流动行为和脱气受到积极影响的组合物,其结果是能够实现非常光滑的,基本上无孔的表面。 组合物可以由混合物组成或包含含有至少一种组分(a)的混合物,该组分(a)包含化合物N,其在水性含水泥粘结剂体系中显示润湿作用,并且含有至少一种另外的组分(b),其包含 在水性含水泥粘合剂体系中具有消泡性的化合物E。 组分a)中的化合物N可优选为非离子或两性表面活性剂,优选烷基烷氧基化物或甜菜碱。 组分b)中的化合物E优选可以是载体材料上的聚醚聚硅氧烷。
