Fließfähiges, hydraulisch abbindendes Mörtelsystem

摘要

The invention relates to a flowable, hydraulic setting mortar system comprising a powder component (A) and a liquid component (B). Component (A) contains: between 20 and 60 weight % of at least one hydraulically setting binding agent, between 30 and 70 weight % fillers, between 0.1 and 5 weight % additives and between 0 and 5 weight % of a redispersible polymer powder. The liquid component (B) contains an aqueous, anionic bitumen emulsion, as well as possibly water and/or an aqueous polymer dispersion on a vinyl or acrylate basis. The mortar system provided for in the invention is suitable for producing self-levelling flowable floor surface toppings which owing to their excellent resistance to frost and de-icing salt in relation to existing systems can also be used outdoors. In addition, set products obtained using the mortar provided for in the invention have a comparatively low elastic modulus and a relatively favourable ratio of bending tensile strength to compression resistance of 1:3.
