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 cementitious material comprising:
hyaloclastite having a volume-based mean particle size of less than or equal to approximately 40 μm; and
a mineral or compound having reactive hydroxyl groups.

2. The cementitious 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 cementitious 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 cementitious 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 cementitious material of claim 1 , wherein the mineral or compound having reactive hydroxyl groups is CaOH.

6. The cementitious material of claim 5 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 20 μm.

7. The cementitious material of claim 5 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 10 μm.

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

9. The cementitious material of claim 1 , wherein the mineral or compound having reactive hydroxyl groups is CaO.

10. The cementitious material of claim 9 further comprising water.

11. A cementitious-based material comprising:
aggregate;
hyaloclastite having a volume-based mean particle size of less than or equal to approximately 40 μm;
a mineral or compound having reactive hydroxyl groups; and
water.

12. The cementitious-based material of claim 11 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 20 μm.

13. The cementitious-based material of claim 11 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 10 μm.

14. The cementitious-based material of claim 11 , wherein the hyaloclastite has a volume volume-based mean size of less than or equal to approximately 5 μm.

15. A method of making a cementitious material comprising combining:
hyaloclastite having a volume-based mean particle size of less than or equal to approximately 40 μm;
a mineral or compound having reactive hydroxyl groups; and
water.

16. The method of making a cementitious material of claim 15 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 20 μm.

17. The method of making a cementitious material of claim 15 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 10 μm.

18. The method of making a cementitious material of claim 15 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 5 μm.

19. The method of making a cementitious material of claim 15 , wherein the mineral or compound having reactive hydroxyl groups is CaOH or CaO.
