Abstract

The invention comprises a composition comprising a natural pozzolan selected from hyaloclastite, sideromelane or tachylite, wherein the natural pozzolan has 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 a natural pozzolan selected from hyaloclastite, sideromelane, tachylite or combination or mixtures thereof, wherein the natural pozzolan 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 a natural pozzolan selected from hyaloclastite, sideromelane, tachylite or combination or mixtures thereof, wherein the natural pozzolan 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 a hydraulic cement and a natural pozzolan selected from hyaloclastite, sideromelane, tachylite or combinations or mixtures thereof, wherein the natural pozzolan has a volume-based mean particle size of less than or equal to approximately 40 μm.

2. The cementitious material of claim 1 , wherein the natural pozzolan 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 natural pozzolan 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 hydraulic cement comprises portland cement.

5. The cementitious material of claim 2 , wherein the hydraulic cement comprises portland cement.

6. The cementitious material of claim 3 , wherein the hydraulic cement comprises portland cement.

7. The cementitious material of claim 1 , wherein the natural pozzolan comprises approximately 10% to approximately 99% by weight amorphous form.

8. The cementitious material of claim 1 , wherein the natural pozzolan comprises approximately 15% to approximately 99% by weight amorphous form.

9. The cementitious material of claim 1 , wherein the natural pozzolan comprises approximately 20% to approximately 99% by weight amorphous form.

10. A cementitious-based material comprising:
aggregate;
a cementitious material comprising a hydraulic cement and a natural pozzolan selected from hyaloclastite, sideromelane, tachylite, or combinations or mixtures thereof, wherein the natural pozzolan has a volume-based mean particle size of less than or equal to approximately 40 μm; and
water sufficient to hydrate the cementitious material.

11. The cementitious-based material of claim 10 , wherein the natural pozzolan has a volume-based mean particle size of less than or equal to approximately 20 μm.

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

13. The cementitious-based material of claim 10 , wherein the hydraulic cement comprises portland cement.

14. The cementitious-based material of claim 11 , wherein the hydraulic cement comprises portland cement.

15. The cementitious-based material of claim 12 , wherein the hydraulic cement comprises portland cement.

16. The cementitious material of claim 10 , wherein the natural pozzolan comprises approximately 10% to approximately 99% by weight amorphous form.

17. The cementitious material of claim 10 , wherein the natural pozzolan comprises approximately 15% to approximately 99% by weight amorphous form.

18. The cementitious material of claim 10 , wherein the natural pozzolan comprises approximately 20% to approximately 99% by weight amorphous form.
