<p>Coated hydraulic binder (I) obtained by applying a coating composition that includes one or more compounds comprising (A1) amine compounds and/or their salts, (A2) polyamine compounds and/or their salts, (A3) quaternary ammonium salts, (A4) fatty acid salts of polyvalent metal ions, (A5) fatty acid mixtures comprising at least one saturated and unsaturated fatty acid and/or their salts, (A6) silane compounds or their oligomers, (A7) silazane compounds, (A8) polysiloxanes containing at least one silicon-hydrogen (Si-H) bond, and (A9) titanium compounds to a hydraulic binder, is claimed. Coated hydraulic binder (I) obtained by applying a coating composition that includes one or more compounds comprising (A1) amine compounds of formula (NR1R2R3) and/or their salts, (A2) polyamine compounds of formula (R1-[NH-CH 2-CH 2-CH 2] n-NH 2) and/or their salts, (A3) quaternary ammonium salts of formula ([NR1R2R3R4] +>X(n-) 1/n), (A4) fatty acid salts of polyvalent metal ions, (A5) fatty acid mixtures comprising at least one saturated and unsaturated fatty acid and/or their salts, (A6) silane compounds of formula ((R5O) 3Si-R6) or their oligomers, (A7) silazane compounds of formula ((R7) 3Si-NH-Si(R7) 3), (A8) polysiloxanes containing at least one silicon-hydrogen (Si-H) bond, and (A9) titanium compounds of formula (TiY1Y2Y3Y4) to a hydraulic binder, which is cement or calcium sulfate, is claimed. R1 : 6-40C hydrocarbon group; R2, R3 : H or 1-40C hydrocarbon group; n : 1-5; R4, R5, R7 : 1-6C-alkyl group, where R5 is preferably methyl or ethyl; X(n-) : anion; R6 : 4-30C hydrocarbon or -(CH 2) n1-Y11; n1 : 0-3; Y11 : methacrylic or vinyl group; and Y1-Y4 : saturated or unsaturated 1-30C hydrocarbon groups, saturated or unsaturated carboxylic acid groups, 1-30C-alkoxy groups, or di-(1-30C-alkyl)phosphate groups. Independent claims are included for: (1) an aqueous suspension of the coated hydraulic binder (I); and (2) a two-component system containing the coated hydraulic binder or the aqueous suspension as first component and an activator as second component, where the hydraulic response is triggered by the combination of the two components.</p> |
