Abstract

Disclosed is a method of spraying a surface with a set-delayed cement. The method comprises providing a set-delayed cement composition comprising water, pumice, hydrated lime, and a set retarder; spraying a surface with the set-delayed cement composition; and allowing the set-delayed cement composition to set on the surface.

Claims

1. A method of spraying a surface with a set-delayed cement composition, the method comprising:

providing a set-delayed cement composition comprising water, pumice, hydrated lime, and a set retarder;

spraying a surface with the set-delayed cement composition; and

allowing the set-delayed cement composition to set on the surface.

2. The method of claim 1 wherein the set retarder comprises at least one retarder selected from the group consisting of a phosphate, a phosphonate, a phosphonic acid, a phosphonic acid derivative, a lignosulfonate, a salt, an organic acid, a carboxymethylated hydroxyethylated cellulose, a synthetic co- or ter-polymer comprising sulfonate and carboxylic acid groups, a borate compound, and any mixture thereof.

3. The method of claim 1 wherein the set-delayed cement composition further comprises a cement set activator selected from the group consisting of a zeolite, amine, silicate, Group IA hydroxide, Group HA hydroxide, monovalent salt, divalent salt, nanosilica, polyphosphate, and any combination thereof.

4. The method of claim 3, wherein the set-delayed cement composition comprising the cement set activator further comprises a thickening time in a range between about 30 seconds to about 10 minutes.

5. The method of claim 1 wherein the set-delayed cement composition further comprises a fiber.

6. The method of claim 1 wherein the set-delayed cement composition further comprises a dispersant selected from the group consisting of a sulfonated-formaldehyde-based dispersant, a polycarboxylated ether dispersant, and any combination thereof.

7. The method of claim 1 further comprising, prior to the spraying step, storing the set-delayed cement composition for a period of at least about 1 day.

8. The method of claim 1, wherein the surface is disposed about, on, or within a mine, a pond, a creek, a river, the ocean floor, a beach shore, a wall, a ceiling, a floor, an attic, or a basement.

9. The method of claim 1, wherein the set-delayed cement composition is disposed within a mine and wherein the set-delayed cement composition is pumped from a vessel outside of the mine into the mine.

10. The method of claim 1, wherein the set-delayed cement composition is foamed.

11. The method of claim 1, wherein the set-delayed cement composition comprises refractory materials.

12. The method of claim 1, wherein the set-delayed cement composition comprises a dye and/or beads.

13. A method of coating a surface with a set-delayed cement composition, the method comprising:

providing a set-delayed cement composition comprising water, pumice, hydrated lime, and a set retarder;

coating a surface with the set-delayed cement composition; and

allowing the set-delayed cement composition to set on the surface.

14. The method of claim 13 wherein the set retarder comprises at least one retarder selected from the group consisting of a phosphate, a phosphonate, a phosphonic acid, a phosphonic acid derivative, a lignosulfonate, a salt, an organic acid, a carboxymethylated hydroxyethylated cellulose, a synthetic co- or ter-polymer comprising sulfonate and carboxylic acid groups, a borate compound, and any mixture thereof.

15. The method of claim 13 wherein the set-delayed cement composition further comprises a cement set activator selected from the group consisting of a zeolite, amine, silicate, Group IA hydroxide, Group IIA hydroxide, monovalent salt, divalent salt, nanosilica, polyphosphate, and any combination thereof.

16. The method of claim 13 wherein the set-delayed cement composition comprising the cement set activator further comprises a thickening time in a range between about 30 seconds to about 10 minutes.

17. The method of claim 13 wherein the coating a surface with the set-delayed cement composition comprises painting the surface with the set-delayed cement composition or dipping the surface into a vessel containing the set-delayed cement composition.

18. A cementing system comprising:

a set-delayed cement composition comprising;

water,

pumice,

hydrated lime,

a set retarder, wherein the set-delayed cement composition is capable of remaining in a pumpable fluid state for at least about one day at 80°

F.;

a cementing unit comprising;

a vessel,

a conduit; and

a nozzle coupled to the conduit.

19. The cementing system of claim 18 wherein the cementing unit further comprises a pneumatic system comprising a gas compressor, a compressed gas, and a compressed gas conduit, wherein the compressed gas conduit is coupled to the nozzle, and wherein the compressed gas is capable of spraying the set-delayed cement composition.

20. The cementing system of claim 18, wherein the cementing unit further comprises a hydraulic system coupled to the nozzle, wherein the hydraulic system is capable of spraying the set-delayed cement composition.
