MINERALISCHEN BAUSTOFFMASSEN
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.
