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 mixture comprising:
a mineral formed from molten lava or magma that has been quenched by water to form a fragmented, solid mineral, wherein the mineral comprises greater than 69% by weight SiO 2 , wherein the mineral comprises approximately 10% to 99% by weight amorphous form and wherein the mineral is reduced in size to a plurality of particles having a volume-based mean particle size of less than or equal to approximately 40 μm, wherein the mineral is hyaloclastite and wherein the plurality of particles have pozzolanic properties; and
a hydraulic cement.

2. The mixture of claim 1 , wherein the mineral comprises approximately 15% to approximately 95% by weight amorphous form.

3. The mixture of claim 1 , wherein the mineral comprises approximately 15% to approximately 90% by weight amorphous form.

4. The mixture of claim 1 , wherein the mineral comprises approximately 5% to approximately 20% by weight Al 2 O 3 .

5. The mixture of claim 1 , wherein the mineral is rhyolitic.

6. The mixture of claim 1 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 20 μm.

7. The mixture of claim 1 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 10 μm.

8. The mixture of claim 1 , wherein the mineral comprises approximately 30% to approximately 95% by weight amorphous form.

9. The mixture of claim 1 , wherein the mineral comprises approximately 50% to approximately 95% by weight amorphous form.

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

11. A mixture comprising:
a mineral formed from molten lava or magma that has been quenched by water to form a fragmented, solid mineral, wherein the mineral comprises greater than 69% by weight SiO 2 , wherein the mineral comprises approximately 10% to 99% by weight amorphous form and wherein the mineral is reduced in size to a plurality of particles having a volume-based mean particle size of less than or equal to approximately 40 μm, wherein the mineral is hyaloclastite and wherein the plurality of particles have pozzolanic properties;
aggregate;
a hydraulic cement; and
water sufficient to hydrate the hydraulic cement.

12. The mixture of claim 11 , wherein the mineral comprises approximately 15% to approximately 95% by weight amorphous form.

13. The mixture of claim 11 , wherein the mineral comprises approximately 15% to approximately 90% by weight amorphous form.

14. The mixture of claim 11 , wherein the mineral comprises approximately 5% to approximately 20% by weight Al 2 O 3 .

15. The mixture of claim 11 , wherein the mineral is rhyolitic.

16. The mixture of claim 11 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 20 μm.

17. The mixture of claim 11 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 10 μm.

18. The mixture of claim 11 , wherein the mineral comprises approximately 30% to approximately 95% by weight amorphous form.

19. The mixture of claim 11 , wherein the mineral comprises approximately 50% to approximately 95% by weight amorphous form.

20. The mixture of claim 11 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 5 μm.
