Cement-containing mixture for materials with 'easy to clean' properties by modification of uncured material with fluorine-containing actives

摘要

The present invention relates to a hydraulic setting mixture comprising: a) 6% to 25% by weight of cement, b) 50% to 90% by weight of at least one aggregate, and c) 0.001% 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 hydraulic setting mixture of the invention for producing materials, more particularly components, concrete articles or mouldings, for example as face concrete, where the surface of the materials exhibits only relatively low soiling tendency (easy-to-clean property) even on abrasion.
