Thixotropic compositions for coloring cement or concrete or similar products comprise particulate pigment particles (about 20-80% by weight), at least one stabilizer (about 0.4-15%), a dispersent (about 0.1-3.0%) and water (about 12-77%). Methods of making these compositions are also explained.

Coloring compositions for concrete or mixes or the like comprising: (a) about 20-70% by weight of a solid particulate pigment, (b) about 0.4-15% by weight of a stabilizer, (c) about 0.1-3% by weight of a dispersant, and (d) about 12-77% by weight of an aqueous carrier which has been mixed and milled to form a thixotropic slurry. A colored concrete or cementitious mixture comprising, (a) a thixotropic coloring slurry comprising (1) about 20-70% by weight of a solid particulate pigment, (2) about 0.4-15% by weight of a stabilizer, (3) about 0.1-3% by weight of a dispersant, and (4) about 12-77% by weight of an aqueous carrier, said slurry having been mixed and subjected to high-energy milling whereupon it is rendered thixatropic and (b) a wet cement or concrete mix with which said thixotropic slurry has been mixed.
