A pigment paste and a method for making the same that alters the appearance of concrete such that, after the concrete sets, it resembles natural stone concrete sets, it resembles natural stone (e.g., marble, granite, sandstone, bluestone, etc.) without separately applying a finish of any kind to the concrete are provided. The pigment paste preferably comprises a filler, a pigment, an anti-foaming agent, a surfactant, and water. In some embodiments, the surfactant is a water reducing admixture. A concrete compound having a finish resembling natural stone is made by combining the pigment paste with a concrete mix, which includes a cementitious material with aggregate and water, and a chemical admixture. Upon adding the pigment paste and mixing it, the cementitious material is allowed to set, where, after it sets, the concrete has a finish resembling natural stone.

What is claimed is: 1. A pigment paste composition for allowing concrete to resemble a natural stone comprising: a non-binding filler, the paste characterized by the absence of a binding filler; a pigment; an anti-foaming agent; a surfactant; and water. 2. The composition of claim 1 wherein the filler is an alumino-silicate microsphere. 3. The composition of claim 1 wherein the filler is a grey alumino-silicate microsphere. 4. The composition of claim 1 wherein the filler is a white alumino-silicate microsphere. 5. The composition of claim 1 wherein the filler is fly ash. 6. The composition of claim 1 wherein the pigment is chromium oxide. 7. The composition of claim 1 wherein the pigment is titanium oxide. 8. The composition of claim 1 wherein the anti-foaming agent is in powder form . 9. The composition of claim 1 wherein the surfactant is sodium salt of sulfonated naphthaleneformaldehyde condensate. 10. The composition of claim 1 wherein the surfactant is sodium salt of naphthaleneformaldehyde condensate. 11. The composition of claim 1 wherein the surfactant comprises a sulfonate-formaldehyde condensation product. 12. The composition of claim 1 wherein the surfactant is a water reducing admixture. 13. A pigment paste composition for allowing concrete to resemble a natural stone comprising: a non-cementitious filler, the paste characterized by the absence of a cementitious filler; a pigment; an anti-foaming agent; a water reducing admixture; and water. 14. The composition of claim 13 wherein the filler is an alumino-silicate microsphere. 15. The composition of claim 13 wherein the filler is fly ash. 16. The composition of claim 13 wherein the pigment is chromium oxide. 17. The composition of claim 13 wherein the pigment is titanium oxide. 18.

The composition of claim 13 wherein the water reducing admixture is sodium salt of naphthalenesulphonic condensate. 21. The composition of claim 13 wherein the water reducing admixture comprises a sulfonate-formaldehyde condensation product. 22. A method for creating a pigment paste for use with cementitious materials using a mixer having a low speed and a high speed, comprising: adding water into the mixer; adding a surfactant to the water; setting the mixer at the high speed for a first given time to ensure that the surfactant is dissolved in the water; setting the mixer at the low speed; adding a pigment to the water and the surfactant; adding a powder mixture to the pigment, the water, and the surfactant, wherein the powder mixture comprises a non-binding filler, the paste characterized by the absence of a binding filler, and an anti-foaming agent; and mixing the powder mixture, the pigment, the water, and the surfactant at the high speed for a second given time to form the pigment paste. 23. The method of claim 22 wherein the low speed is between about 180 RPM to about 360 RPM. 24. The method of claim 22 wherein the high speed is between about 380 RPM to about 1,700 RPM. 25. The method of claim 22 wherein the filler is an alumino-silicate microsphere. 26. The method of claim 22 wherein the pigment is chromium oxide. 27. The method of claim 22 wherein the pigment is titanium oxide. 28. The method of claim 22 wherein the anti-foaming agent is in powder form. 29. The method of claim 22 wherein the surfactant is sodium salt of sulfonated naphthaleneformaldehyde condensate. 30. The method of claim 22 wherein the surfactant is sodium salt of naphthalenesulphonic condensate. 31. The method of claim 22 wherein the surfactant comprises a sulfonate-formaldehyde condensation product. 32. The method of claim 22 wherein the surfactant is a water reducing admixture. 33. The method of claim 22 wherein the first given time is between about five minutes and about ten minutes. 34. The method of claim 22 wherein the second given time is between about three minutes and about ten minutes. 35. The method of claim 22 wherein the mixing further comprises mixing the powder mixture, the pigment, the water, and the surfactant until it achieves a viscosity between about 1,200 SMA to about 1,500 SMA. 36. A method for creating a pigment paste for use with cementitious materials using a mixer, comprising: adding water into the mixer; adding a surfactant to the water; dispersing the surfactant in the water; adding a pigment to the water and the surfactant; adding a non-cementitious filler to the pigment, the water, and the surfactant; adding an anti-foaming agent to the filler, the pigment, the water, and the surfactant; and mixing the anti-foaming agent, the filler, the pigment, the water, and the surfactant to form the pigment paste, the paste characterized by the absence of a cementitious filler. 37. The method of claim 36 wherein the mixing further comprises mixing until the pigment paste achieves a viscosity between about 1,200 SMA to about 1,500 SMA. 38. The method of claim 36 further comprising adding additional water to the anti-foaming agent, the filler, the pigment, the water, and the surfactant. 39. The composition of claim 1 wherein the anti-foaming agent includes a defoamer. 40. The composition of claim 13 wherein the anti-foaming agent includes a defoamer. 41. The method of claim 22 wherein the anti-foaming agent, includes a defoamer.
