NOVELTY - Curable mixture comprises: at least one mineral binder (more than 25 wt.%, based on the total amount of the curable mixture); at least one fluoroorganic-substituted silicon compound (0.001-8 wt.%, based on the total amount of the curable mixture), which is adsorbed on a solid; and optionally further added substances.    USE - The curable mixture is useful as a mortar, preferably dry mortar or a two-component mortar, tile grout, repair mortar, powder paint, adhesive putty, plaster, in particular top coat, gypsum, lime and/or cement plaster, leveling mortar, troweling compound, industrial flooring mass, bonding mortar, sealing compound, thermal insulation mortar, ceramic tile adhesive, primer, concrete paving tiles and/or as cement-based mass for crude oil, natural gas and/or geothermal heat boreholes (all claimed).    ADVANTAGE - The curable mixture: provides cured mixture with hydrophobic and oleophobic properties (claimed), and is excellent dirt-repellent i.e. easy-to-clean-properties not only on the surface, but all through the whole mass and the properties are permanent and independent of abrasion, cracks and weather, and has high compressive strengths; can be obtained with simple working steps and in economical manner; has good wettability with water and mortar workability when mixed with water; utilizes fluoroorganic-substituted silicon compounds adsorbed on a solid and preferably in a fee-flowing form can be stored, transported and handled easily, e.g. for sacking, transporting, weighing and dosing when making the curable mixture; and reduces costs for cleaning and maintenance by prolonged cleaning cycles.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) preparing the curable mixture, comprising either mixing the fluoroorganic-substituted silicon compound, with at least one component of the curable mixture or preparing a component (i) comprising the mineral binder and a component (ii) comprising the fluoroorganyl-substituted silicon compound and mixing the further added substances with components (i) and/or (ii), and mixing (i) and (ii) with one another;    (2) preparing a cured mixture, comprising mixing the curable mixture with water (1-120 wt.%, based on 100 wt.% of curable, water-free mixture);    (3) cured mixture with hydrophobic and oleophobic properties obtained by the above process; and    (4) use of fluoroorganic-substituted silicon compound which is adsorbed on a solid, in a hydraulically curable mixture containing hydraulically setting binder (25-60 wt.%), at least one added substance (20-74 wt.%) and the fluoroorganic-substituted silicon compound (0.001-8 wt.%) and optionally further adjuvants (0-40 wt.%) based on 100 wt.% of curable, water-free mixture.
