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 comprising:
placing in a form or a mold a cementitious-based material comprising:
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;
aggregate; and
water sufficient to hydrate the cementitious material; and

allowing the cementitious material to at least partially cure.

2. The method 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 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 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 claim 1 , wherein the hydraulic cement comprises portland cement.

6. The method of claim 2 , wherein the hydraulic cement comprises portland cement.

7. The method of claim 3 , wherein the hydraulic cement comprises portland cement.

8. The method of claim 4 , wherein the hydraulic cement comprises portland cement.

9. The method of claim 1 , wherein the cementitious material comprises approximately 50% to approximately 99% by weight portland cement and approximately 1% to approximately 50% by weight hyaloclastite.

10. An object or structure made by the method of claim 1 .

11. An object or structure made by the method of claim 2 .

12. An object or structure made by the method of claim 3 .

13. An object or structure made by the method of claim 4 .

14. An object or structure made by the method of claim 5 .

15. An object or structure made by the method of claim 6 .

16. An object or structure made by the method of claim 7 .

17. An object or structure made by the method of claim 8 .

18. An object or structure made by the method of claim 9 .

19. An object or structure made from 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.

20. The object or structure of claim 19 , wherein the hydraulic cement is portland cement.
