Abstract

The invention comprises a composition comprising hyaloclastite having a volume-based mean particle size of less than or equal to 40 μm. The invention also comprises a cementitious material comprising a hydraulic cement and hyaloclastite, wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 40 μm. The invention further comprises a cementitious-based material comprising aggregate, a cementitious material comprising a hydraulic cement and hyaloclastite, wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 40 μm and water sufficient to hydrate the cementitious material. A method of using the composition of the present invention is also disclosed.

First claim

What is claimed is:

1. A method of making a cementitious-based material comprising combining a hydraulic cement and hyaloclastite, wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 40 μm.

2. The method of making a cementitious-based material of claim 1 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 20 μm.

3. The method of making a cementitious-based material of claim 1 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 10 μm.

4. The method of making a cementitious-based material of claim 1 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 5 μm.

5. The method of making a cementitious-based material of claim 1 , wherein the hydraulic cement comprises portland cement.

6. The method of making a cementitious-based material of claim 2 , wherein the hydraulic cement comprises portland cement.

7. The method of making a cementitious-based material of claim 3 , wherein the hydraulic cement comprises portland cement.

8. The method of making a cementitious-based material of claim 4 , wherein the hydraulic cement comprises portland cement.

9. The method of making a cementitious-based material of claim 5 , wherein the cementitious-based material comprises approximately 50% to approximately 90% by weight portland cement and approximately 10% to approximately 50% by weight hyaloclastite.

10. The method of making a cementitious-based material of claim 6 , wherein the cementitious-based material comprises approximately 50% to approximately 90% by weight portland cement and approximately 10% to approximately 50% by weight hyaloclastite.

11. The method of making a cementitious-based material of claim 7 , wherein the cementitious-based material comprises approximately 50% to approximately 90% by weight portland cement and approximately 10% to approximately 50% by weight hyaloclastite.

12. The method of making a cementitious-based material of claim 8 , wherein the cementitious-based material comprises approximately 50% to approximately 90% by weight portland cement and approximately 10% to approximately 50% by weight hyaloclastite.

13. A method comprising grinding hyaloclastite rock such that the ground hyaloclastite has a volume-based mean particle size of approximately 40 μm.

14. The method of claim 13 , wherein the hyaloclastite has a volume-based mean particle size of approximately 20 μm.

15. The method of claim 13 , wherein the hyaloclastite has a volume-based mean particle size of approximately 10 μm.

16. The method of claim 13 , wherein the hyaloclastite has a volume-based mean particle size of approximately 5 μm.

17. A method comprising:
grinding hyaloclastite rock to form a powder; and
screening the powder with a 325 mesh screen, wherein approximately 80% to approximately 100% by volume of the powder passes through the screen.

18. The method of claim 17 , wherein approximately 90% to approximately 100% by volume of the powder passes through the screen.

19. The method of claim 17 , wherein approximately 95% to approximately 100% by volume of the powder passes through the screen.

20. The method of claim 17 , wherein approximately 95% to approximately 100% by volume of the powder passes through the screen.
