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 product comprising ground hyaloclastite that has been reduced in size from its natural state, wherein the ground hyaloclastite comprises less than 53% by weight SiO 2 and has a volume-based mean particle size of less than or equal to approximately 40 μm.

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

3. The product of claim 1 , wherein the ground hyaloclastite has a volume-based mean particle size of less than or equal to approximately 15 μm.

4. The product of claim 1 , wherein the ground hyaloclastite has a volume-based mean particle size of less than or equal to approximately 10 μm.

5. The product of claim 1 , wherein the ground hyaloclastite has a volume-based mean particle size of less than or equal to approximately 5 μm.

6. A product comprising ground hyaloclastite that has been reduced in size from its natural state, wherein the ground hyaloclastite comprises approximately 53% to approximately 57% by weight SiO 2 and has a volume-based mean particle size of less than or equal to approximately 40 μm.

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

8. The product of claim 6 , wherein the ground hyaloclastite has a volume-based mean particle size of less than or equal to approximately 15 μm.

9. The product of claim 6 , wherein the ground hyaloclastite has a volume-based mean particle size of less than or equal to approximately 10 μm.

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

11. A product comprising ground hyaloclastite that has been reduced in size from its natural state, wherein the ground hyaloclastite comprises approximately 57% to approximately 63% by weight SiO 2 and has a volume-based mean particle size of less than or equal to approximately 40 μm.

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

13. The product of claim 11 , wherein the ground hyaloclastite has a volume-based mean particle size of less than or equal to approximately 15 μm.

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

15. The product of claim 11 , wherein the ground hyaloclastite has a volume-based mean particle size of less than or equal to approximately 5 μm.
