1. A lime milk comprising:
at least 40 weight % of dry matter composed of hydrated lime;
0.1 to 3 dry weight % of carbohydrate dispersants selected from a group of monosaccharides, disaccharides, oligosaccharides, alkoxide forms of the monosaccharides, disaccharides, and oligosaccharides, and derivatives thereof obtained by oxidation or hydrogenation;
0.1 to 3 dry weight % of a dispersant from a family of polycarboxylic polyether copolymers obtained by copolymerization of unsaturated ethylene monomers having between 15 and 100 moles of C2-C3 oxyalkylene groups, and unsaturated ethylene monomers of mono-or dicarboxylic acids, and/or their salts and/or C1-C4 alkyl esters thereof, wherein a proportion between the dry weight % of the dispersant of the carbohydrate type and the dry weight % of the dispersant of the copolymer type is between 5:1 and 1:1;
wherein a particle size distribution of hydrated lime includes:
at least 99% of particles having a size lower than 100 μm;
at least 75% of particles having a size greater than 1.2 μm.
