Abstract
The present invention relates to a hydraulically setting mixture comprising: a) 6% to 25% by weight of cement, b) 50% to 90% by weight of at least one aggregate, and c) 0.01% to 8% by weight of at least one fluoroorganyl-substituted silicon compound, and also to materials produced from this mixture, more particularly components, concrete articles or mouldings. The invention further relates to the use of a hydraulically setting mixture of the invention for producing materials, more particularly components, concrete articles or mouldings, for example as facing concrete, where the surface of the materials exhibits only relatively low soiling tendency ('easy-to-clean' property) even on abrasion.
